Solving the Tannin Bleeding Problem
At times, we come across siding on homes that develop a splotchy, brown or grey discoloration as they age. Simply applying latex paint over these areas will not resolve the issue. It is a recurring problem, especially on Masonite and cedar siding, often caused by tannic acid bleed-through, particularly around knots in the wood. Additionally, binders and resins in particle board used for Masonite siding can surface, leading to a similar unsightly, splotchy appearance, even through latex paint.
Solution: After years of experience in this field, I have found that using a high-grade oil-based primer can effectively seal off these bleed-through problems in both types of siding. Latex primer is not suitable for this job and will not deliver satisfactory results. It’s important to note that while oil-based primer can be painted over with latex paint, the opposite is not true.
Attempting to paint over oil-based paint with latex paint will result in peeling. This is due to the sheen of oil-based paint preventing proper adhesion of latex paint. However, since oil-based primer has no sheen, latex paint bonds well to it.
