You can use latex or acrylic paint outdoors. Although acrylic paint tends to last longer outside, it also costs more, so if you’re painting the outside of your house, for instance, latex paint is often a go-to option. However, acrylic will be your best choice if you want to spend some extra money for added durability.

Wood stain is typically dry to the touch within 6 to 12 hours, but it is not fully cured at this point. You should wait at least 24 hours before applying a second coat or a protective finish. For surfaces like decks, avoid walking on them for at least 24 to 48 hours, and wait even longer before placing furniture. The full curing process can take from 24 hours to one week, depending on the type of stain. Factors like high humidity and cold temperatures can extend drying and curing times, so it's wise to allow for extra time in these conditions.

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.

Avoid using cleaning products that are abrasive or contain bleach or acidic components on composite decking to avoid discoloration. Early-generation Trex decking isn’t designed to handle pressure washer cleaning—and if you use them on second-generation boards, always use a low setting to avoid the risk of damage that can risk voiding your warranty.
