Limewash and whitewash do not harm surfaces if you apply them correctly. Use on non-suitable surfaces can cause issues. For instance, applying limewash or whitewash to surfaces with existing sealants or incompatible materials may lead to poor adhesion or flaking. Also, harsh cleaning agents on limewashed or whitewashed surfaces can damage the finish. Proper preparation, application, and maintenance ensure that limewash and whitewash do not harm surfaces.

A five-gallon bucket of deck stain will cover roughly 875 square feet in a single coat. Actual coverage will vary based on the type of wood you’re staining and the number of coats. If you plan on doing multiple coats, multiply the square footage by the number of coats to calculate how many buckets of stain you’ll need.

Yes, staining or sealing a cedar deck or fence is highly recommended to extend its lifespan, typically by five to 10 years. While cedar is naturally resistant to mold and mildew, it can still fall victim to moisture, sun exposure, and rot over time. Applying a treatment creates a protective shield that helps prevent splintering, fading, and decay, preserving the wood's strength and appearance. A combination stain and sealer often provides the best protection, as it soaks into the wood grain rather than just sitting on top. This offers superior defense against UV damage and rot and lasts longer than a sealer alone. To maintain the wood's natural look, consider using a near-translucent stain. You should plan to reapply the stain or sealer every two to three years.

The best paint for an older deck depends on the material and whether or not your deck already has a coat of paint. Generally, if your deck already has paint on it, you should choose the same type of paint when repainting the deck. For example, if an old deck has oil-based paint on it, stick with oil; if your deck has water-based paint, choose water-based paint.
