Preparing a non-skid deck

A deck demands a tough coating to protect it from everyday wear and tear. Where a non-skid surface is required Interlux offers 3 alternative solutions.

Step 1: Health and Safety

Before commencing preparatory work, ensure the area you are working in is adequately ventilated. Ensure you are wearing the correct PPE; we recommend safety glasses, goggles or visors, nitrile rubber gloves, overalls (ensuring skin is not exposed) and a solvent mask.

Previously painted surfaces:

Step 2: Inspection

Check for areas of damage, separation or peeling, or any other indications that the existing coating is not firmly adhered to the substrate.

Step 3: Preparation – in good condition

Bare fiberglass
Begin by scrubbing well using soap and water and a stiff brush. Rinse with fresh water and allow to dry. Wipe a small area with a clean rag that has been wetted with Fiberglass Solvent Wash 202.

While the surface is still wet, wipe with a clean, dry rag. Continue this process until the entire surface has been cleaned. Sand using 180-220 grit paper. Remove sanding residue.

Molded fiberglass
Working in small areas at a time, scrub the area using Fiberglass Surface Prep YMA601 and coarse bronze wool or maroon Scotch-Brite® pad. Be sure to scrub in different directions and wipe off the residue off before it dries. This will remove all contamination and provide a good anchor pattern to which the paint can adhere. Rinse with fresh water.

Preparation – in poor condition
If previous finish is cracking, peeling or showing signs of separation from the substrate this should be totally removed.

Step 4: Masking

Before priming or applying a deck finish, mask off the area to be painted.

Bare substrate:

Step 5: Priming

Your choice of primer will be determined by the substrate and the choice of deck finish product. Priming recommendations are provided on labels and data sheets. Remember to pay particular attention to drying times and overcoating intervals.

Using Interdeck (ready-mixed formula):

Step 6: Application

Sand the primer (if used) with 180-220 grit wet or dry paper. Remove dust with a dust wipe or tack rag, according to label recommendations. 




Mix Interdeck thoroughly; apply 1-2 coats. For best results either stipple by brush or use a mohair roller.

Using non-skid Additive (hand-mixed method):

Step 7: Application

Sand primer (if used) with 180-220 grit wet or dry paper. Add 4-6 ounces of Interlux Intergrip 2398c per quart of Perfection or Brightside. 



Mix thoroughly. Apply 1-2 coats to deck area, using a brush or roller. For best results either stipple by brush or use a mohair roller.

Using non-skid Additive (broadcast method):

Step 8: Application

Sand primer (if used) with 180-220 grit wet or dry paper. Apply one coat of Interlux Perfection or Brightside.



While the paint is still wet, sprinkle Interlux Intergrip 2398c over the surface. Allow to dry thoroughly following the recommendations provided on the finish label. Remove excess Intergrip. Apply second coat of finish.
