Can I apply latex (water-based) paint directly over an existing alkyd (oil-based) paint?

Yes, you can, provided you use a 100 per cent acrylic coating or one of our new waterborne hybrid coatings. Before you begin, the surface must be thoroughly washed with TSP and rinsed with clear water. When dry, rub down with 120-grit sandpaper to de-gloss the existing coating prior to painting. For maximum adhesion, we recommend using a bonding primer before you paint.
