What if the paint peels off and loses its luster?

Peeling paint is often caused by an overly smooth surface, especially if the original coating was lacquered or had a powdery texture. In such cases, new paint may not adhere properly. Another common reason is wood decay or metal rust, which can also cause peeling. Poor quality paint is another culprit. For small areas, sand the affected spot with fine sandpaper, apply putty, then prime and repaint. For larger areas, scrape off the old paint completely before repainting.

If the paint is bubbling, start by pricking the bubbles to let the moisture escape. If water is present, it likely means there's moisture beneath the paint layer or behind the wall. When the sun heats up, the moisture evaporates and causes the paint to blister. Use a hot air gun to remove the blistered paint, let the wood dry naturally, apply primer, and then repaint the area. If no water is inside the bubble, it might be due to trapped air in the wood grain. In this case, scrape the blistered area, fill the cracks with resin filler, and repaint. Alternatively, you can skip the filler and just repaint after scraping.

Cracks in the paint usually require removing the damaged layer first. You can use a chemical paint remover or a heat gun for this. For minor cracks, use a sanding block or wet/dry sandpaper to smooth out the surface, then apply putty, prime, and repaint.

Stains on painted surfaces can occur when water from latex paint dissolves materials on the wall or causes rust. Rubbing the wall with steel wool can also create rust spots, and leaks from pipes behind the wall may result in stains. To prevent this, apply a primer containing aluminum powder. If stains appear, remove the affected paint, apply the aluminum-based primer, and repaint.

The loss of gloss in paint is often due to improper preparation—like skipping the primer or applying varnish too soon. Poor-quality varnish can also contribute to this issue. To fix it, sand off the old paint, clean the surface, wipe it with a damp cloth, and allow it to dry. It’s also important to avoid painting in very cold conditions, as this can affect the finish.

Rough paint surfaces are usually caused by dirty brushes or contaminated paint. Sometimes, paint that hasn’t been filtered properly or has dust on it during drying can cause this problem. Always use clean brushes and containers, and filter old paint through a sieve or nylon stocking before using. Cover the painted area with a cloth or cardboard while it dries to prevent dust. If the surface is already rough, sand it with wet/dry sandpaper, wipe it clean, and repaint.

If the paint is drying too slowly, it could be due to poor ventilation or low temperatures. Open all windows and doors to improve airflow, or use a heater to raise the room temperature. If the problem persists, the surface may be oily. In that case, use a chemical paint remover or heat to clean the surface thoroughly before repainting.

If insects stick to the paint surface, wait until the paint is dry before gently removing them. Apply a small amount of oil to lightly touch up the area. If the paint is already drying, wait until the film is fully hardened before wiping away the bug to avoid leaving marks.

By understanding these common paint problems and following the right steps, you can maintain a beautiful and long-lasting finish on your walls. With proper care and attention, your home will always look its best.
