I used a paddle attachment with a power drill to mix the sand into the complete gallon, prior to pouring the 1st quart to add the catalyst. power mixed the remainder, before pouring each of the next batches. I used the cheep roller covers and the hotdog style handle from HD. Was able to do a gallon with 1 cover. Was able to stand in the hatches, and did not have any hatch rings to deal with.be sure to also stir the gelcoat with the non skid in it when u can, otherwise it will settle in the pot. lastly, use rollers made for chemicals/ resin etc...this will prevent the roller from coming apart during your project..
This is how I have been doing the non skid on my project. I take the can of additive with a few 1/8 inch holes and shake it into the wet paint. I have then been rolling back over it all while still wet. This helps drive the sand into the paint and actually helps to make it all very evenly dispersed. The gunnels have been holding up great getting in and out a million times.Most guys down here use Awlgrip for decks and either mix in the Awlgrip particulate (can't recall the name) for a one shot painting process or use sand in a two step operation. I did mine with sand, which is a more aggressive deck but if done right will look good and last. Roll the paint on and have someone follow along with sand in a container w/ holes in the top like a big salt shaker and shake the sand onto the wet paint. Revisit it the next day with a shop vac and suck up all the loose sand. Then roll another coat of awlgrip and your done. I actually use thinned epoxy paint (toluene is good to cut it w/) but it doesn't hold up to the sun so it gets dull after several months, and if you use the white epoxy paint it will turn yellowish (I used gray and it's fine f/ what we do and less glare after the shine goes away.) Anyway it's another option and relatively simple for two people to do. Also if you do the sand thing and you use painters tape around your edges and hatches and such you will have a much nicer result than if you don't. The little slick borders make for an attractive pattern. Although Awl Grip is an expensive product, a little goes a long way.
It holds up well with sinkers, totes and normal wear and tear. Not sure it it would be good with heavy abuse or not. One thing I find is the paint doesn't chip off like the gel coat did for me. But that's me.Hey Mike, would the alwgrip hold up on a commercial boat..with things dragged and dropped and stuff like that...because i will be looking for something down the road other then gelcoat
