How long does deck stain or sealer need before rain?
Most deck and concrete coatings need a rain-free day after application, and a few need two. Many manufacturers only say not to apply if rain is expected within a set time.
Quick answerIt depends on the exact product. The manufacturers' stated times we track:
- Rain-safe: from 4 hours (BEHR PREMIUM Solid Color Waterproofing Stain & Sealer (No. 5011)) to 2 days (Rust-Oleum Concrete & Garage Floor Paint + Primer) across 18 products.
