Beyond liquid rubber, homeowners can use sealants, stains, membranes, or tapes as waterproofing options. Oil-based or water-based sealants soak into the wood, creating a moisture-resistant barrier. Waterproofing stains—available in transparent, semi-transparent, and solid colors—add both protection and style to your deck. For heavy-duty waterproofing, deck membranes and waterproof tapes can be applied under the deck boards to direct water away from the structure below. Whatever method you choose, clean and prep the deck first to ensure the best, longest-lasting results.

The best type of paint for concrete exterior surfaces like concrete porches, steps, or walkways is high-quality exterior-grade paint with strong weather resistance. Acrylic latex blends with tiny anti-slip particles will help create an anti-slip coating for your concrete porch. This type of paint will stand up best to the elements, especially rain, snow, and ice. An exterior epoxy will also help strengthen your concrete porch.

It is definitely worth sanding a deck to ensure the wood absorbs new stain. Sanding a deck removes the outer layers of aging wood, allowing the stain to penetrate. It also gives a fresh look to the entire surface as part of the deck refinishing process. Without sanding, your stain or sealant is less likely to absorb into the wood. While sanding a deck is a time-intensive project, the rewards are noticeable and long-lasting.

Whether to brush or roll stain on wood depends on the project and your preference. Brushing is ideal for smaller, intricate areas and offers more control over the application, ensuring thorough coverage and penetration into the wood's grain. 

Conversely, rolling is efficient for more extensive, flat surfaces and can save time. However, it is not always the best fit for textured or uneven wood. Some projects may benefit from combining both methods, using a brush for detail work and a roller for broader areas. Ultimately, the choice between brushing and rolling depends on the specific requirements of your staining project.
