Painting exterior paint over interior paint is possible, but it must be done correctly. Follow these steps to ensure durability and a smooth finish;
Before painting, inspect the wall for peeling, flaking, dampness, or cracks. Exterior paint will not adhere properly to damaged interior paint. Repair any surface issues before moving ahead.
The bonding of exterior paint is hindered by dust, grease, and residue. Use water and a light detergent to clean the wall. Allow it to fully dry. A smoother finish and improved adherence are guaranteed by this stage.
Use medium grit sandpaper to gently sand the interior painted surface. This makes the surface rougher and less glossy, which improves the adhesion of the exterior paint. Use a fresh cloth to remove dust.
Using a high quality exterior primer is essential. Primer seals the old interior paint and creates a strong base for exterior paint. One coat is usually enough, but apply two if the previous paint is very glossy or patchy.
Depending on the surface, choose textured paint or weather-resistant, UV-protected exterior emulsion. Exterior paint is thicker and designed to withstand harsh outdoor conditions.
Apply the first coat evenly using a brush or roller. Before applying the second layer, let it completely dry. To avoid peeling, the right drying period is essential.
Look for any uneven areas or missed spots, then do any necessary touch-ups.
By following these steps, you can successfully apply exterior paint over interior paint and achieve long lasting results.
