How do you paint non-skid decks?
Although there is no single, universally proven deck surface that will prevent people from slipping on a boat deck, a low-cost, slip resistant finish gives added protection and can be created easily.
A deck demands a tough coating to protect it from the damaging effects of foot traffic, anchors and other gear that descend upon it so a two part polyurethane paint like Perfection® with a non-skid additive like International’s Intergrip is your best option. You aren’t limited to using a two-part paint though, you can also add Intergrip to a one part paint like Toplac® or you could use Interdeck which is pre-mixed and already contains a non-slip additive.
How to apply the Intergrip material
There are various ways of applying the actual Intergrip material and it comes down to personal preference as to how you might wish to approach the job. You may have other ideas and it really do seed.esn’t matter as long as you achieve the effect you want.
- The easiest way is to shake the Intergrip powder onto a layer of wet paint. One way to do this is to take the Intergrip container and drill many 3 mm holes in the lid and use the container like a large pepper shaker. Shake the powder on until the whole surface is covered by a layer of powder. Allow the paint to semi-cure and then blow the excess powder off the surface and apply a further coat of paint to seal it all down. The jar of Intergrip that now has a holey lid can easily be sealed by using a layer of cling wrap over the top before putting the lid back on.
- Another way is to stir the Intergrip into the paint and then apply. This method can be a little tricky, as you have to ensure the Intergrip doesn’t bunch up under the roller or brush giving a patchy effect.
- The other method is to hand broadcast the Intergrip on to the surface as if you are sowing grass
How to produce the non-skid area
- Firstly ensure the second coat of the top coat you applied is well cured and that you adhere to the drying and overcoating times listed on the topcoat label.
- Mask the area off in the pattern intended for non-skid. You can use 3M® 218 Fine line masking tape which will go around curves very well or you can use normal masking tape laid down in strips at the corners and then carefully cut into a curve. Cans and jars of various sizes are useful as templates to achieve the exact curve you want.
- Paper mask off the area you want to protect.
- Lightly abrade the exposed areas with 280 grade paper.
- Apply one coat of topcoat as described in the top coating section of this booklet.
- Using one of the methods described above apply the Intergrip material while the Perfection® is still very wet.
- Allow the coat of paint to dry for the appropriate period. Do not exceed the overcoating time, as you will have to sand, which is not easy on a non skid surface.
- Very carefully vacuum or blow off any excess Intergrip.
- Carefully apply a second coat of Perfection® topcoat taking care to tip this coat without over brushing.
- Allow to dry for a few days before allowing heavy traffic use.
