Why paint peels in Singapore, and how to make a new coat last

You repaint a wall, and within a year it bubbles, flakes or grows black spots. In Singapore's heat and humidity this is common, and it is almost always a preparation problem, not a paint problem.

The usual reasons paint fails

Moisture in the wall

If water is getting into the wall from a leak, a crack or rising damp, paint will bubble no matter how good it is. The water has to be stopped first.

Painting over old, loose paint

New paint only holds as well as the layer under it. If the old coat is chalky or flaking, the new coat lifts with it.

Mould left under the paint

Painting over mould hides it for a few weeks. Then it grows back through the new coat. It must be treated and cleaned before painting.

Wrong paint for the area

Exterior walls, bathrooms and kitchens need paint made for moisture and weather. Interior paint on an outside wall will not last.

How we prepare a wall

1. Find and fix the cause of any damp, stain or crack.
2. Scrape and sand loose and flaking paint.
3. Treat mould and let the surface dry.
4. Fill cracks and holes, then sand smooth.
5. Apply a sealer or primer suited to the surface.
6. Two finish coats of the right paint for the area.

Tips before you repaint

• Ask what preparation is included, not only the price per room.
• Ask which paint brand and product will be used.
• Plan exterior painting for a dry spell when possible.

How Steer Builders helps

We paint interiors, exteriors, ceilings, roofs and gates. Because we also repair roofs, ceilings and plumbing, we can stop the leak behind the stain before we paint over it.
