Interior walls, ceilings and exterior facades
Wall paint is typically used on interior walls and ceilings in living areas, hallways, kitchens, bathrooms and utility rooms. Facade paint is intended for exterior masonry, render, plaster and other mineral building surfaces exposed to weather, UV and dirt. Even when the colour looks similar, the demands on interior and exterior coatings are not the same.
Wall paint, washable paint and facade paint
Standard wall paint is often sufficient for lower-stress interior areas where even coverage and a clean finish matter most. Washable interior paint makes more sense in spaces exposed to everyday wear, moisture or regular cleaning, while facade paint is the exterior option for durability and weather resistance. Thermal interior paints can also sit within this category, but they should be viewed as a specialist wall-paint option rather than a substitute for insulation.
What matters before painting
Substrate condition has a direct effect on the final result, especially on plaster, masonry and repaired surfaces. Absorbent, chalky or uneven areas may need primer or another preparation step before the paint is applied. Choosing wall or facade paint therefore works best when the decision is based on interior versus exterior use, substrate type and cleaning demand.
