Which is the best season to paint my house?

The weather conditions prevailing while painting is a deciding factor for a lifetime of the paint applied. The weather conditions for the interior paint can be managed in most of the cases. However, for the exterior painting, we will have to pay attention towards external temperature and moisture conditions. The ideal conditions for oil-based painting are between 20 to 37 Deg C and for water-based latex paints are between 23-37 Deg C. You should avoid painting on the exterior on a sunny or windy day. Extreme sunlight or wind dries paint before its time and may lead to paint failures like blisters, craters, and peeling.
Painting cannot be done in the rainy season too. Rain will just wash away your exterior paint. Also during the rainy season, there will be a build-up of humidity in the atmosphere. This humidity will prolong the drying periods of most of the water-based products where water is used for thinning the product for application purposes. It can also equally affect the over-coating intervals. Under the duress of completing the job work, if the painter or contractor doesn’t give enough over coating periods, it can lead to poor paint property development. This can eventually result in lessened durability and short-term performance. The issues of prolonged drying times can happen during the winter season as well. In short, a day with no rain, usual temperature, and the low wind is your best day for painting.

I have built a new villa. When shall I start painting?

Alkalinity on the cement plaster imposes various types of issues to the water-based wall coatings. If the pH is more than 10, we should not be coating the wall ideally. In exterior conditions, if we leave the wall in its ambient weather conditions for 1.5 – 2 months, the curing of the cement will be improved. The pH of the wall too will come down making it fit for the application. For interior conditions, we need to provide a slightly prolonged duration like 3-5 months before which it can be coated.

What are the best means to clean the stains on the painted walls?

Common stains, like pencil marks, crayons etc., can be easily cleaned. But tough stains like curry stains etc are difficult to clean. You may try using a mild detergent to clean the stains. However, enough care should be exercised not to remove the paint as excessive scuffing can delaminate the paint.

How to take care of the floor and granite slabs while painting?

Any paint droppings should be wiped off immediately before the paint dries. Use a mop and clean up each room after the painting is over. Enamel paint droppings require thinner for cleaning if it has started drying.

While buying paints what should I look for in the labels?

All household paints should have less than 90 PPM lead levels and you should look for the same mentioned by the manufacturer on the label. You should also look for MRP values. The money you pay for a particular paint sold in the container should not be more than the MRP mentioned on the container.

I am confused with various terminologies used like Acrylic, Emulsion, etc. What do they mean?

The term acrylic is usually coined for the nomenclature and description of water-based paints to denote better durability and finish. It will have certain acrylic components incorporated in its binders to facilitate these preferred properties.
Emulsion paints or emulsions which they are usually called are water-based topcoat products used basically for application over interior and exterior primed concrete wall surfaces.

When I go to a dealer, for a particular brand or company, there are different types of paints. Which one should I choose?

For a particular company or brand, the dealer may display and sell various varieties of Interior and Exterior paints which are usually differentiated as regular and premium. The regular and premium emulsions are clearly distinct from each other in terms of its durability, finish and color development. Our premium products like Special Effects provide mild sheen to the walls thus providing a rich and classy look in a properly lit room.

When I call the painter, he tells me about primer, putty, top coats, etc. What are these things?

Top coats are paints which are applied over the primed surfaces to provide the final finish, color, and aesthetics. Putty and primers are used to improve the performance and aesthetics of the top coat and are always applied underneath the top coat.
A good practice is to sandwich the putty layer between two primer layers. Putty is a kind of paste prepared for applying on to primed walls to fill in any minor dents or to level the surface.
First, a primer layer is applied directly onto the new concrete to improve the adhesion. Then a putty layer is applied. On top of the putty layer, a primer layer is applied. This primer layer takes away the unevenness caused by putty and the final paint comes out perfect.

What is the correct painting procedure?

For newly constructed Interior Surfaces

  • Apply one coat of water-based interior primer directly on to the wall after enough maturation (3-5 months) is provided to the newly plastered interior wall
  • Use a suitable acrylic wall putty to make the undulations, pores and dents
  • Sand the putty after it dries
  • Apply another coat of interior primer over the sanded putty surface to make the surface even and lesser absorbing
  • Apply one or more coats of the chosen emulsion paint after the primer has dried to provide the required finish, colour and sheen levels

Apply a suitable topcoat to provide the required finish, colour and sheen

  • Inspect the interior surface to be painted for adhesion of the existing paint
  • Sand the existing paint to improve the adhesion of the new paint over the existing paint
  • Apply the interior primer

For newly constructed Exterior Surfaces

  • Apply one coat of water-based interior primer directly on to the wall after enough maturation (1.5-2 months) is provided to the newly plastered exterior wall
  • Apply one more coat of the primer if the plastered texture is too porous
  • Apply two coats of the suitable topcoat to provide the required finish, colour and sheen levels

For re-painting the Exterior Surfaces

  • Inspect the exterior surface to be painted for adhesion of the existing paint
  • Sand the existing paint to remove any dried algae or dirt and to improve the adhesion of the new paint over the existing paint
  • Apply a coat of exterior primer
  • Apply a suitable topcoat to provide the required finish, colour and sheen

After how much time, can I use a painted room?

Even though the paint dries in 3-10 hours after application, the smell and fumes of the paint remain inside the room for several days. Provide proper ventilation while application and also after that. Leave the room ventilated for 3-5 days and after that, you can use the painted room for regular usage. It should be kept in mind that the duration before which you can use the painted room depends on the quality of the ventilation provided.

What is the green / brownish colour stuff that grows on any walls? How shall I avoid it?

The greenish film that grows on the exterior walls are algae and the brownish cover that covers the inside of the bathrooms and other moist areas are fungi. Fungi usually happen when there is no direct sunlight and there is dampness. Algae can be avoided by using our Safeguard series and fungi can be avoided by using Robbialac or Special effects series. But the surface needs to be properly prepared and primer applied before their usage.

What is the difference between emulsion and enamel?

Emulsions or emulsion paints are water-based paints used for the application on the exterior or interior wall surfaces. The enamel paint is a solvent based paint used for application on gates, windows, grills, etc after applying suitable primers. In some cases, enamel paints are applied on interior wall surfaces to get glossy and stain resistant finishes.

How shall I remove the mud stains on my walls due to the nearby vegetation?

The mud stains on the walls can be removed by the water wash. In some cases, a mild scuffing can help to remove the thickly adhered stains. However, enough care should be exercised not to remove the paint, as excessive scuffing can delaminate the paint.

Is there a specific paint for bathroom/kitchen, where more water splashes happen?

Sheenlac has designed a new premium paint called Opulence series. The paint type can be found in water-based interior paint portfolio. This premium paint is highly hydrophobic and repels water and stains. Due to its special properties, this paint offers superior cleanability properties where any stains or dirt can be easily cleaned with less effort. The usual practice is to apply enamel paints in the bathroom and kitchen areas. However, Opulence series provides much better durability and finish compared to conventional enamels.

What are the best paints for my gates and window grills?

  • The gates and grills are usually made of metal surfaces and the surface needs to be prepared before painting them
  • Sand the surface using 80# emery paper. This emery paper helps in removing any loose rust
  • Wipe the surface using enamel thinner or MTO. This ensures removal of any oily stains or sanding dust
  • Prime the prepared surface within 6 hrs of surface preparation using Sheenlac Red oxide zinc chrome primer or Sheenlac red oxide primer. This is done to obtain corrosion resistance and adhesion properties
  • Allow the primer to dry adequately
  • Apply the topcoat enamel- Shyne to obtain a uniform glossy finish
  • Use Sheenlac epoxy zinc phosphate primer followed by Sheenlac Polyurethane topcoats if your location is nearer to a coast. This is to give the coat a better corrosion-resistant property

What are the differences between wood polish, oil and varnish?

Wood Polish

Wood polishes give good look on wood. But if your location is in a high traffic area the durability is of the polish is limited. They are ideally suited for wardrobes, and structures like wooden wall paneling and banisters that require minimal protection.

Wood Oil

Wood oil offers more durability than wood polish. They are easy to work with and are easy to repair. If scratches form on the wooden surface, the surface can be sanded and wood oil can simply be reapplied. The disadvantages of wooden oil are they have slow drying time and they virtually provide no gloss.

Wood Varnish

Wood varnishes are single-pack alkyd-modified polyurethane clears. They form a seal on the surface of the wood as they are applied and they are the strongest in its category. Among the wood varnishes, a 2-pack PU varnish is the strongest form. It is ideal if your wooden assets are located in high traffic areas where durability is of utmost importance. A perfect example of a wooden asset in high traffic location is a bar top. The more coats of wood varnish on such wooden assets, the better is their durability.

How do we check if the wood has been Polished, NC Lacquered or Varnished?

If a wooden surface looks like it has been coated already with a product it is always good to find out what type of finish it has. The product you might want to apply to the wood can get affected and may not provide the desired finish.
For example, you cannot apply a 2-pack PU over a polished or varnished door. However, an existing door that has been NC Lacquered can be re-coated with STYL PU varnish or Melmyn Wood finishes, after cleaning. Here are few pointers to find out what your wood has been finished with.

  • Try putting a little NC Thinner on a small unnoticeable area. If it is brittle and dissolves the surface coating then it is likely to be a Shellac wood polish
  • Try buffing it with a cloth soaked in NC Thinner. Most wood-polished surfaces will become shinier once buffed

If the wood has NC Lacquered Surfaces

  • Try buffing the surface with a cloth soaked in NC Thinner. The surface coat will melt and shine. You are also likely to see a fuzzy image reflected from the surface
  • Keep in mind that NC Thinner also dissolves most shellac polishes. Hence check if the surface is wood-polished first and then perform this buffing method for checking if the wood has NC Lacquered Surface

If the wood has Varnished Surfaces

  • A varnished surface is hard to a touch
  • It also has a reflective surface. Even a matt varnish reflects light more than a Shellac polished surface
  • Try buffing the surface with a cloth soaked in NC Thinner. The coat on the wood with varnish surface does not dissolve easily in NC Thinner

How Sheenlac Thinners stand apart from other similar products?

Sheenlac is conscious in its decision to avoid harmful and hazardous ingredients like re-cycled or distilled materials which may contain ingredients not relevant for paint application. The company as a policy does not employ compositions or formulations that are not safe to use. Sheenlac Thinners are specifically benzene-free. It is worth mentioning that benzene is highly carcinogenic in nature. Our standards are steadfastly aligned with the health and safety of our end-users and the environment.

Can we use STYL single-pack PU varnish, Melmyn or 2-pack PU wood finish over freshly applied wood polish?

No, it is not advisable to use STYL single-pack PU varnish, Melmyn or 2-pack PU wood finish over freshly applied wood polish. Any application leads to cracks or peed-offs in a shorter period. As a ground rule, avoid using different topcoats on each other as the chemical composition, drying properties, and other parameters vary from one topcoat to another. Wood polish does not seal the wood but other topcoats might seal the wood. So applying other topcoats on a wood polished surface can lead to instability of the topcoat.

How to define the different levels of gloss or sheens?

Matt (10 & 20 Sheen)

This level of gloss has no shine or has very little shine. Sheen level of 10 is referred as Dead Matt and has a flat, velvet-like finish. Sheen level of 20 is referred as Normal Matt where some coating is visible. However, three coats of matt varnish will produce a sheen that is the equivalent to the next level of sheen called Satin.

Satin (30 Sheen)

Eggshell is another way to describe satin. This is because the sheen level is about the same as the surface of an egg on an application of a single coat. However, three coats is a bit shinier.

Semi-Gloss (60 Sheen)

It is a level of gloss where there is a traditional glossy-look but it is not really a high gloss. The sheen level is also referred as a buttery gloss. The edges and carving areas get highlighted in a better way in this sheen level.

Gloss (> 85 sheen)

It is a level of gloss with very shiny and reflective surface. If you hold an object against a piece of wood that had two to three coats of a gloss varnish applied, a clear reflection of the object is produced on the wood.

What is Wood Stain and what are they used for?

Wood Stains are transparent liquids that don’t offer any sheen or protection. They simply color or stain the wood. Usually, better results are achieved if clear coats are applied on top of the wood stain.
Our interior wood stains are solvent-based, medium concentrated, and are available in 14 natural wood colors. The exterior wood stains are solvent or water-based and are available in 4 primary colors.

What are the benefits of a solvent-based stain?

The biggest benefit of a solvent-based stain is their ability to dry quickly within about 15 minutes. Their usage does not cause grains of the wood to rise. The solvent-based stain mixes with undercoat sealers and gives more definition and depth to the color.

What are the benefits of a water-based stain?

Water-based stains can be used in both interiors and exteriors, and are very easy to apply. They are odorless and are resistant to UV.

Are Wood Polishes suitable for bare wood interior doors?

Wood Polishes are one of the best options for bare wood interior doors. They nourish the bare wood doors and prevent it from drying out. Hence they protect the door from shrinking, splitting and warping. Wood polish finish is also very easy to maintain. They can be easily repaired if the surface becomes dirty, scuffed or scratched.

What varnish type should we use for our internal veneered doors and wardrobes?

We recommend STYL Single-pack PU varnish for internal veneered doors and wardrobes. It is a solvent-based clear varnish and is available in Satin and High Gloss levels of sheen.

What varnish type should we use for our interior furniture and table tops?

We recommend Melmyn or Aspire Furniture PU for interior furniture and table tops. They are solvent-based 2-pack clear varnish and are available in Matt and High Gloss levels of sheen. They are pale yellow to amber in color. They are highly suitable if the wooden asset is in a high traffic area and are subject to heavy-duty use.

What varnish type should we use for our kitchen cabinets, light-colored Interior furniture or wood carvings?

We recommend Opulence Interior PU for kitchen cabinets, light-colored Interior furniture or wood carvings. They go well with wood like rubber wood, white cedar etc. It is a solvent-based 2-pack Premium protective PU clear varnish and is available in Matt and High Gloss finish. They possess non-yellowing character and offer good flexibility by not chipping or becoming brittle.

Can we paint Melamine or PU Lacquers over a previously Polished or Varnished interior door?

If the doors have been previously polished or varnished, there is a good chance that the paint will not effectively bond or adhere to the door surface. The paint simply peels off, runs off or drips off the door surface. We would advise that the doors be professionally stripped off the paint first. It is indeed possible to remove the old finish by sanding or using a paint remover but you need to keep in mind that this is a time-consuming job.

Can we apply Interior Wood Finish during a rainy season?

It should be kept in mind that every product has its own drying time and the drying time is affected by atmospheric temperature and humidity. Hence it is generally not recommended to apply interior wood finish during rainy seasons. However, if you do apply during a rainy season, let the drying period between the coats be extended.

Is a Wood Finish “heat-proof”?

Sheenlac’s Wood Finishes have a higher flash point than wood. This means the wood may get damaged when the finish is exposed to high heat. We recommend using coasters when setting hot items on the wooden surface such as coffee mugs, casserole dishes, or pots to ensure maximum wood protection.

Is a Clear-wood Finish “Termite proof”?

None of the Wood Finishes is termite-proof. Hence we recommend treating the termite affected wood with quality anti-termite solutions available in the market. You need to do this before you start off with any wood finishing job.

What types of Finishes are best for outdoor usage?

In general, climatic conditions like moisture, humidity, rain, and temperature shifts and atmospheric conditions like UV in the sunlight are factors that can potentially damage your wood.
If your wood is going to be placed outdoors, it is best to protect it with STYL Plus 1K Urethane varnish or Opulence 2-pack Exterior PU. These finishes are designed specifically for woods used in outdoors. They also offer special protection to outdoor wood against UV light, temperature changes, and moisture. STYL Plus works great on most outdoor wood. But if you are nearer to the coast, we recommend using Opulence 2-pack Exterior PU only.

How do we retain the natural color of the wood on the exterior?

Look out for a light-colored wood stain to retain the natural color of the wood on the exterior. Apply Sheenlac water-based semi-transparent wood stain on the bare wood. This wood stain available in four primary colors preserves the wood from fungal growth. The added benefit is the resultant amiable color it produces. The semi-transparent water-based wood stains have pigments that act as UV blockers and reflectors. Hence they offer impeccable UV protection.
We caution not to use any Clear finish for exterior woods as they do not protect the work from UV. It is worth mentioning that UV can damage the wood and discolor the finish. Exterior wood that has been coated with Clear finish looks good for a shorter period only. They later develop patches of faded and dark surfaces on the wood. They generally become blotchy; give a weathered look and has an unaesthetic appeal. Hence pigmented finishes are durable than clear finishes on exterior woods.

What is the life for an exterior wood finish? When do we generally do recoating?

The large exposed area of an exterior wood that has been finished perfectly can remain unaffected for many years. All they require is simple maintenance. But wood joints and horizontal surfaces get damaged easily and can extend the damage to other areas of the wood. Take care to follow all the recommended guidelines for treating the wood for finishing the topcoat. It is always better to keep a close watch on the appearance of the wood by examining them periodically as recommended. When the finish begins to go dull and dry, you need to understand that it is time for another protective coat of Clear finish. This coat rejuvenates the exterior wood and also adds a layer of protection simultaneously. If the degradation has proceeded to the bare wood, then maintenance becomes a challenge.

Here is a simple test to check the condition of the finish

  • Spray the surface of the wood with water lightly
  • If the water beads up, the integrity of the finish is still good. However, if the water soaks right into the wood, it needs to be understood that it is time for a recoat

Can we apply the Exterior Wood Finish during a rainy season?

It should be kept in mind that every product has its own drying time and the drying time is affected by atmospheric temperature and humidity. Hence it is generally not recommended to apply exterior wood finish during rainy seasons. However, if you do apply during a rainy season, let the drying period between the coats be extended. If you do not allow the extended drying time, the results may be poor and you run the risk of redoing the work entirely from the beginning. Hence we recommend that you diligently observe the weather conditions before getting down to applying the exterior wood finish.

How do we remove the stains on the floor after the painting is over?

Take care to wipe off any paint stains immediately. If they have dried, use Sheenlac NC Thinner D-13X and scrub the stains off the floor.

Do Sheenlac Paints produce only Thinners & Polish?

At Sheenlac, we provide complete solutions for Interior and Exterior Wood protective coatings apart from thinners and wood polishes. The solutions so produced are for both industrial and household application products. We also produce a full range of decorative wall finishes and automotive refinishing products. The range we produce includes ancillaries, undercoats, fillers, primers, Topcoats, protective clears etc. You can click the product catalog here to access the assorted products we manufacture.

What are Wood Fillers and Sealers?

Wood Fillers and sealers are applied on the bare wood surface. This application is done much before the clear wood finish is applied finally. A filler is a transparent paste applied on the wood to fill any minor dents or grain pores. A sealer is a layer laid on top of the filler. The sealer fills the minor pores on the bare wood. A sealer effectively smoothes and evens out the surface. A sealer coat is essentially a barrier coat between bare wood and topcoats. In the absence of a sealer coat, the appearance of the final topcoat will not be aesthetic as the performance of the topcoat has been compromised.

What are Wood Primers and Metal Primers?

Any Primer paint, be it a wood primer or a metal primer, is the first layer of coating that is applied to wood or metal respectively before applying the topcoat.
Wood primer seals the pores and hides the background color of the wood. This is true for hardwood or man-made plywood. Wood primers are highly suitable for woods like Padauk. Trees like Padauk have high oil content and clear wood finish from such trees’ woods are difficult to withstand.
Metal primers are used mainly for imparting corrosion resistance property on the metal surface. They also ensure a proper adhesion of the topcoat paint to the surface.
Both wood and metal primers enhance the durability of paint and impart extra safety to the surface they are painted. They also improve the appearance, if applied as per recommended guidelines.

How many hours can we keep thinned paint?

You can keep a thinned paint for 24 hours. Take care to use the thinned paint within the specified time.
