I want to seal up my sanded finish board. I bought both quarts not spay cans of water based Varathane Diamond finish and a oil based Deft clear wood varnish. which one would be the best choice?.I have used both products on wood and like the Deft much better but I have never tried these on a surfboard… I usually usually use a acrylic floor finish on my sanded finishes but I want something that is a little more durable and will hopefully seal up tiny pin holes
…the wood sealers are not better than automotive ones…
so, you can use : -acrilyc varnish or polyester varnish and add a matte element…
I wouldn’t recomend either one of these finishes for a surfboard. As a cabinet finisher and painter in a past life, I know both of these materials well. They are both excellent for their intended purposes, which have nothing to do with surfcraft. If I wanted to use a durable spray on finish, I would use a clear acrylic. Fiberglass Hawaii sells one, the name of escapes me. You can also buy clear urethanes and epoxies that can be sprayed. Try an automotive paint supplier. Omni is cheaper than PPG and very durable. Sailboard manufacturers use these for final clear coat. If I had to choose between the two you mentioned I would go with the water-born. It won’t yellow, Deft will. If you want a durable finish, learn to do it the traditional way and gloss with resin. McDing
…with PU varnishes (clears) you must use catalyst and like the epoxie ones, they´re extremely “shine ones”…also are too much thick (for a board application)…so, you must try with acrlylic or poliester based…and put the finish with around 80 lbs pressure…
I was thinking water based Varathane was basically like a concentrated form of acrylic floor finish? PU. Home Depot sell a product in spray and cans by minwax called PolyUrethane. I am not really into using a rattle can on my surfboard. McDing I got one of them HVLP spray gun things. 80 lbs would be way to much but thanks for the info…
I use Diamond Coat Varithane sprayed from my gun, it works great, hasn’t blushed in the water and is a pretty tough finish
Yeah I’ve used it , but prefer the others. Sometimes the waterbornes are a little difficult to spray and dry slower. Mcding
I didn’t recomend 80 lbs, that was someone else. Maybe someone else can get away with that ,but that would be too much pressue for me. Especially that water-borne stuff. It is in my opinion too watery to begin with and therefore likly to run. Honestly though I don’t use spray on finishes on any thing but epoxy. I do alot of sailboard and surftech repair, so I use urethane paints and clear coat by Omni. I 've used the Depot stuff a few times on small repairs. I use the Depo clear urethane in a can for small epoxy repairs. For boards I build, I either gloss with resin or wipe dowm with Future. McDing

I’ve been using a PU varnish lately, it is not thick at all and flow out beatifully compared to the other varnishes I’ve tried. I’m applying it with a foam roller and foam brush, but it could easily be used with a spray gun IMHO. You can also get thinners for it, but I don’t think you would need it. It is VERY scratch resistant.

oops sorry Mcding…that was reverb
Jim, if Varathane is good enough for a genius I will give it a try. thanks
…varathane or others wood sealers don´t work better than automotive finish…
…wood varnishes don´t sticky so well in resin…
…i understand that 80 lbs is too much for a water based but not for an automotive …, to do a really thin coat…, if not you will obtain a thick and “orange like finish”; also you can put a matte finish (5%) to “kill” the gloss…
-well, i don´t know if you go for a matte or gloss finish…
-yes, if you go for a gloss one, you must try with PU auto varnishes and you will got a thick and gloss finish, but you must finish the sanding job with thinner sandpaper, or the scratches will appear…
Does anyone know if Varithane is available in Australia?
What about a similar product with a different name available in Australia?
