Frequently Asked Question

About the Paint

How do I choose a wall paint?

(a) For rooms with many occupants, use a dirt-resistant and washable paint that does not wear out or discolour easily.
(b) Choose a paint that suits your environment. For example, use a damp-proof paint if you live near the seaside.

Do I need to apply a sealer/primer?

Yes. Applying a sealer/primer serves the following 3 functions:
1. Prevents materials from bleeding through to the surface.
2. Prevents any reaction of the substrate to incompatible top coats.
3. Prevents undue absorption of the subsequent coating into the substrate.
4. Prevents colour fading, flaking and blistering issues of the top coat.

What is an under coat?

It is an intermediate coat formulated to prepare a primed surface or help in preparing the surface for the subsequent finishing coats. Functions include enhancing opacity of the top coat of vibrant colours.

Why is a top coat necessary?

A top coat is the finishing coat of paint that decorates and protects the treated surface. It gives shine, texture and provides tolerance against adverse environmental elements.
About the Method

What are the basic application procedures for painting?

1. Surface preparation: Remove any loose particles with a scraper, apply filler/putty over the holes and sand with sandpaper till it is smooth.
2. Remove dirt, if any, and wait till the surface is dry.
3. Apply 1 coat of sealer/primer.
4. Apply 2 to 3 coats of any top coat.

What are the tips for treating newly plastered walls?

1. Keep the surface dry. Generally, painting should not start if humidity in the atmosphere near the new walls is more than 16%.
2. Use filler to fill up and even out any cracks or uneven areas.
3. Apply 1 coat of sealer/primer to make the top coat smooth and durable.

What are the tips for treating old walls?

1. If the old paint is flaky, remove it completely with a scraper.
2. Sand the wall surface with sandpaper till it is smooth.

How do I calculate the total work area for a painting job?

If you know the floor area of the room, and if the ceiling height is about 2.5m, simply multiply the floor area by 3. If the ceiling height is higher than 2.7m or lower than 2.5m, enlarge or reduce the calculated figure accordingly. This is only a rough calculation. You should also make other considerations, e.g. the area of doors and windows, as required.

What are the common tools used for applying emulsion?

Paint brush, roller and spray gun.

What are the tips for using a new brush?

A new brush may make the paint work imperfect if its bristles drop in the paint. To prevent this, finger the brush back and forth to make the loose bristles drop out. After painting, soak the brush in hot water completely. Lastly, wrap it with paper and keep it aside till it dries.

What should I beware of during painting?

Remove excessive paint from the brush to prevent paint from dripping on the floor and other unwanted areas.

How to paint with rollers?

1. Choose a roller with suitable length.
2. Never let its ends be full of paint.
3. Start the paint work from the edge of the ceiling.
4. Push the roller upward to avoid paint soiling.
5. Paint with an "M" or "W" pattern to make the paint distributed evenly.

What is the difference between painting with a roller or brush?

Using a brush to apply the coat is the simplest and earliest method of painting. It is good for applying paint on various shaped objects. However, it’s quite laborious and time consuming. On the other hand, applying paint with a roller is suitable for large application areas. The end result of using a brush would be better than that of a roller.

Where should I start to paint?

The right sequence of applying the paint is from top to bottom. That is, first applying the paint to the ceiling, then the walls, doors, windows and then the baseboard.

How to treat fungus on walls?

1. High-pressure washing of all affected areas, supplemented with manual scrubbing, if necessary.
2. Treat the surface with an anti-fungus solution to terminate growth of organisms embedded in the concrete.
3. Wash again to remove any residue and allow it to dry.

The old coat is cracked. How should I treat it?

The crack is developed from the concrete. Using high elastic emulsion paint can cover the hairline crack and give high protection to the wall, hence making a smooth and perfect surface to work on.

I’ve discovered that the wall is discolouring. What should I do?

1. Scrape off the discoloured area and sand to smoothen it.
2. Apply one coat of alkaline-resistant sealer.
3. Apply top coats having durable colour and alkaline-resistant features.

Why is there powder on the painted surface after applying the paint?

The formation of loose, powdery pigment on the surface may be caused by various factors:
1. Over-dilution of paint
2. Failure to apply sealer before applying paint
3. High humidity in the application areas

Recommended solution: Remove the chalking areas completely and apply 1 coat of sealer before applying the top coat.

Some “bubbles” (water pockets) have appeared on the interior walls of my house after painting. What should I do?

Possible reasons: Bubbles are caused by water seepage or high humid conditions. Recommended solutions:
1. Avoid painting on a wet or highly humid day.
2. Check for cracks on the walls and patch them with a filler.
3. Scrape off the “bubbles” and sand it to dry.
4. Leave the area to dry completely before painting.

What causes discolouration?

Possible reasons:
1. Long periods of exposure to sunlight.
2. Surface painted with an un-recommended paint type.
3. High moisture present in the walls.
4. Painting exterior surface in the rainy season.
About ECO Paint

How to avoid strong odour during painting?

Using Odour-less interior paints, which have low odour, low VOC (volatile organic compounds), and are water-based. These paints are also safe for health.

What is VOC?

VOCs (volatile organic compounds), which are NOT good for health, are found in a wide variety of everyday products, such as solvent-based paints/coatings, adhesives, sealants, printing inks, many consumer products, organic solvents and petroleum products. All Nippon Paints’ Odour-less products are in compliance with the regulation of “indoor decorating and refurbishing materials limit of harmful substances of interior architectural coatings.”

How to tell if a paint is environment-friendly?

If the VOC is lower than 50gram/litre, it can be claimed as an environment-friendly paint, also known as ‘eco-paint’. All Nippon Paints’ Odour-less products are in compliance with this regulation, and have virtually no odour in the paints.

What is the difference between solvent-based and water-based paints? How do they relate to our health?

Solvent-based paint is diluted with thinner or turpentine, which contain almost 100% VOCs. However, water-based paints are diluted with clear water and contain no harmful elements, making them safe for health. Nippon Paints’ interior emulsion paints are water-based, have virtually no odour, are low in VOC and are not harmful to health.

What is Formaldehyde?

Formaldehyde is a colourless gas commonly used in the industry for the manufacturing of plastic resins that can be used in wood, paper and textile.

Formaldehyde is ubiquitous in the environment, as it is produced from both natural and man-made resources. It exists at low levels in most living organisms as a metabolic intermediate. Major man-made resources of formaldehyde include combustions (e.g. engine exhaust, wood burning, power plant, waste incineration, etc.), building materials and tobacco smoke.

How is formaldehyde harmful to health?

Formaldehyde is a colourless gas commonly used in the industry for the manufacturing of plastic resins that can be used in wood, paper and textile. Major exposure of the general population to formaldehyde is through inhalation of air, especially indoor air.

Formaldehyde is present in or found in recently installed furnishings and building materials. The International Agency for Research on Cancer of the WHO classified formaldehyde as “carcinogenic to humans”.
