How to Make Your Deck Slip Resistant

Decks can become slick after it rains or if they become wet for other reasons, such as swimming pool use.
Some slip-resistant coatings also inhibit mold growth.Some slip-resistant coatings also inhibit mold growth.
Sealers and stains on the deck, whether it is concrete or wood, fill in porous and rough sections, making the surface slippery. This can lead to falls and severe injury. Applying a slip-resistant coating to the deck surface will keep the surface from becoming slick whether it is wet or dry. There are a few preparatory steps you must take to make the coating stick to the surface.

Step 1

Spray the deck surface with a garden hose to remove leaves, twigs, and other debris. Nail down any loose nails. Sand any splintering or rough areas with a 220 grit sandpaper until the spot is smooth.

Step 2

Mix 2/3 cup TSP cleaner in a bucket with 1 gallon of water. Scrub the deck surface with a nylon scrub brush. Rinse with the garden hose and let the deck air dry for 24 hours.

Step 3

Pour the slip resistant deck coating into a paint tray. Coat a paint roller in the liquid. Apply to coating to the deck with the roller, starting at one end of the deck and following the grain of the wood. Apply it to the lengths of the planks, as opposed to across the planks. Strokes should overlap.

Step 4

Let the coating dry according to the directions on the package before using the deck again.
