How to Install Anti-Slip Strips on Deck Stairs

Using a stiff brush and a deck cleaner solution, scrub each stair tread to remove any dirt, grime, mildew, or loose debris. Rinse the stairs thoroughly with water and allow them to dry completely before proceeding. Ensure there is no residual cleaner or moisture on the treads.

Measure the width of the first stair tread where you intend to place the anti-slip strip. Use a tape measure for accuracy. Transfer this measurement to your anti-slip strip material and mark it. Using a utility knife or sharp scissors, carefully cut the strip to the measured width. Repeat this process for all stair treads.

For each stair tread, carefully peel back a small section of the backing paper from one end of the cut anti-slip strip. Align this end with the desired starting position on the stair tread (usually the front edge). Press the exposed adhesive firmly onto the tread. Slowly peel the remaining backing paper as you press the strip down onto the tread, ensuring it lies flat and is firmly adhered without air bubbles. Work from the center outwards to push out any potential air pockets. Repeat for all treads.

After applying each strip, pay special attention to the edges. Use your fingers, a roller, or a putty knife to press down firmly along all the edges of the anti-slip strips. This helps to prevent the edges from lifting over time due to foot traffic and weather exposure.
