Keep The Interiors Dry And Moisture Free
Be mindful of the relative humidity inside the house. Try using kitchen fans or bath fans to keep out the moisture. An ideal relative humidity is below 55% in cold months, but if it is too high, then use fans more frequently.
Repair The Walls
Check your walls for cracks and holes, and repair them. You can use a patching compound for this. Apply the compound with a putty knife and smooth it into a thin layer, to fill in these areas along the wall. Allow the patching compound to dry completely before you repaint the walls.
When you paint first, rough up the old paint on the surface with sandpaper. Small imperfections, indentations or cracks can be mended with this technique.
Use A Good Quality Primer
A primer is used to bind the new layer of paint with the old layer of paint. A primer creates a base so you don't need several coats to cover the old cover. This is because the primer is smooth, and the old layer of paint will not stick to it.
Remove Any Peeling Paint
To stop paint from peeling, it is essential to remove any peeling paint so that moisture cannot work its way under the surface. Use a paint scraper to peel the paint. Push the scraper back and forth to loosen the paint, until you meet strong resistance.
Reseal The Area
By using paint and primer, restore your wall surfaces to look good as new. This will prevent the peeling and damages to your wall in the future. After the primer dries completely, apply a fresh coat of paint over the surface.
A little care and patience is what is required to stop walls from peeling away. But, practise caution when removing, scraping or sanding painted surfaces. Wear a respirator to avoid exposure to paint, or cover your face with a cloth, and you'll be good to go.
