Frequently asked questions on products
Is there a bubble-like bumps on your wall?
What is it?
These bubble-like appearances are caused by blistering, which happens when certain areas lose adhesion, forcing the paint film to lift from the surface.
Possible Causes:
• Due to trapped moisture or gases in paint film (more likely in enamels)
• Painting under direct sunlight or on surfaces that are too warm. This is especially true if the coating you’re using is dark in colour and solvent-based.
• Applying an oil-based finish on a wet or moist surface.
• Exposing water-based finishes to dew, high humidity or rain immediately after the paint has dried. This becomes a greater issue if the surface has not been properly prepared at first, or if the quality of paint is poor.
Solutions:
• Scrape and sand blisters till they go away and then repaint it.
• Remove sources of moisture. Repair loose caulk and install vents and exhaust fans wherever possible.
• Prime and paint the wall with a high quality water-based exterior paint.
Paint coming off as a dusty white powder on your hands?
What is it?
A fine white powder forms on the surface of the finish, usually because of weathering. This can cause the paint to look faded. A little chalking is normal, however heavy chalking can cause the film to wear away.
Possible Causes:
• Applying paint over greasy or very smooth surfaces.
• Applying over loose dust or rust.
• Applying over a glossy coat without first sanding it.
• Using a low quality, high-pigment finish.
• Using indoor finishes on exterior surfaces.
Solutions:
• Always prepare surface correctly before painting.
• Scrub with a stiff brush or wire brush to remove the chalk formation and rinse well.
• Once it is dry, make sure that all chalk residue has been removed.
If the chalking is still present and obvious, use an oil based or acrylic latex primer or sealer. Repaint with a high quality exterior coating.
Why has the paint on my walls started to crack and peel off?
What is it?
Over time, the paint on your walls starts to crack and eventually flakes off in large chunks.
Possible Causes:
• Using a lower quality paint with poor adhesion and flexibility.
• Over thinning and over spreading the paint.
• Poor surface preparation before applying paint.
• Painting wooden surfaces without primer.
• Application of finish coat before drying of the under coat
• Applying quick, hard dry coats over a soft one
Solutions:
• Remove all loose and flaking paint with a scraper or wire brush before repainting. •Also sand and feather the edges.
• Always use a top quality primer and paint top coat.
• If the flaking occurs over multiple layers, use a filler.
• Prime bare wood surfaces before repainting.
• If cracking does go down to the substrate, scrape off all the paint. Sand, and us
Is there a crusty white powder on your walls?
"What is it?
These crusty white deposits, or efflorescence, are caused by salts leaching from the mortar or masonry as water passes through it. "
Possible Causes:
• Not removing all traces of previous efflorescence while preparing surface for painting.
• Excessive moisture rising to the surface of the wall from within.
Solutions:
• Eliminate sources of moisture near the wall by fixing the roof, sealing cracks and cleaning gutters and downspouts. Use a good quality water-based acrylic or siliconised acrylic caulk.
• If moist air is coming from within the building, especially from bathrooms, kitchens and laundry rooms, install vents and exhaust fans to minimise it.
• Remove all traces of it first with a wire brush or powerwasher and rinse the surface thoroughly.
• Apply a masonry sealer and once it is completely dry, coat with a high quality exterior paint.
Is there an uneven little craters on your painted wall?
What is it?
It is a bubbles form on the surface while painting, which then break to form a concave depression or crater.
Possible Causes:
• Use of old paint.
• Applying paint too rapidly, especially with a roller.
• Using a roller cover with the wrong nap length.
• Applying gloss or semi gloss finishes over a porous surface.
Solutions:
• Do not roll or brush too much.
void using paints that are more than a year old.
• All paints have a tendency to foam. New generation water-based paints are however designed to allow the bubbles to break during painting so that the paint applies well and the surface appears smooth.
• Prime and seal porous surfaces before using glossy paints.
• Sand problem areas before repainting.
Why is the paint patchy – darker or lighter – in some places?
What is it?
Patchiness is when the paint does not present a uniform colour and smooth appearance. The thickness and intensity of the film varies in different portions of the wall.
Possible Causes:
• Application of finish coat over puttied surfaces Incomplete drying of putty
• Painting over a highly alkaline surface, which is usually evident in new walls.
• Application of thick coat of putty
Solutions:
• Allow new walls to cure for thoroughly. For already painted surfaces, scrape off old paint and prepare surface correctly.
• Cracks in plaster should be filled with cement sand mixture
• Apply thin coats of putty.
Does your paint coming off in large ribbon like chunks?
What is it?
Paint comes off spontaneously in sheets or ribbons. The peeling could be restricted to only the top coat, or involve subsequent layers of primer and undercoats too.
Possible Causes:
• Excess humidity escaping from inside the home through exterior walls.
• Poor surface preparation before painting.
• Using poor quality paint with less adhesion and flexibility.
• Applying water-based finishes on very hot, cold or windy days.
• Use of improper thinner
Solutions:
• Sufficient drying time between coats
• If there is moisture indoors, install vents and exhaust fans or dehumidifiers if needed.
Use a high quality water-based finish with high adhesion characteristics. This will also permit water vapour to escape without destroying the surface finish.
Can you see the surface through the paint?
What is it?
Poor hiding is when the paint does not completely cover or hide the surface on which it is applied."
Possible Causes:
• The paint is of low quality or contains low hiding pigments.
• The tools are low quality or you use the wrong roller cover.
• Using the wrong combination of tinting base and tinting colour.
• Using a paint that is much lighter than the substrate.
Solutions:
• Use a high quality topcoat with better hiding and flow.
• Use the best tools and recommended roller nap.
• If the substrate is darker, coat it with a wallboard sealer undercoat first.
• If you’re using a low hiding organic paint, apply an undercoat.
Does your walls get dirty and stained easily?
What is it?
If the paint you have used is not equipped to resist absorption of stains or dirt then it will be accumulated easily on your walls.
Possible Causes:
• Using a low quality paint.
• Using a flat finish in areas where there is heavy wear.
Solutions:
• Use high quality water-based paints as they contain more binder. Binders prevent stains from penetrating the paint film, and so they can be washed off easily.
• Prime new surfaces for maximum film thickness, which also helps in easy stain removal.
Does the paint on your wall look wrinkled?
What is it?
Wrinkling is when a painted surface looks rough and crinkled, which usually occurs when uncured paint forms a skin.
Possible Causes:
• Painting over dirty or waxy surfaces.
• Applying paint, especially if it is oil-based, too thickly.
• Uncured paint is exposed to high humidity.
• Top coat is applied in conditions of high humidity.
• Exposing uncured paint to rain, dew.
Solutions:
• Repaint in the right conditions, avoiding high temperatures and extreme humidity.
• Remove wrinkled coating before repainting by scraping or sanding substrate. Apply primer and allow it to dry completely before applying topcoat.
• Use a high quality top coat and apply it evenly and in the right concentration.
• If you’re painting during very hot, cold or damp conditions, give the paint extra drying time between coats.
