Frequently Asked Questions (FAQs)
❓ What is a breathable paint and why is it important?
Breathable paints allow moisture vapour to pass through the wall, preventing trapped moisture that can lead to damp, mould, and paint failure. They are essential for solid wall buildings that rely on vapour diffusion to manage internal humidity.
❓ Can I use breathable paints over modern emulsion or gypsum plaster?
No. For full effectiveness, breathable paints must be applied onto compatible, vapour-permeable backgrounds like lime plaster, mineral render, or bare masonry. All non-breathable coatings should be removed before application.
