Can a roller give me a better finish, I want to apply a solid full pigment top coat, has anyone used a roller before or should I stay with the brush, can I get away with one coat of opaque pigment?
Are you trying to do panels or cover the entire deck?
And are you trying to do this in the hotcoat or gloss?
I do pigmented resin directly on the foam with a roller, but I would not do a “top coat” that way.
Rolling and tipping is a technique used by some guys to paint boats. In some cases it looks as if it were sprayed:
Wow! That rolling and tipping vid is unreal. Looks so easy but I bet it takes a long time to perfect, i.e. coverage, brush pressure, brush angle, brush speed, roller nap, etc. Anyone ever tried it with “gloss” coat epoxy?
Hi, I want to gloss with an opaque/solid colour pigment on an old mal, I have fine sanded the old hotcoat and want to cover up sun damage deçk and bottom , I intend to roller it straight from the paint tray, but concerned it may go on to thin and not hide the damage, applying with a brush would end up being thicker but because im using a hardener catalyst, im worried that I will not be fast enough applying it compared to a roller?
Hi yeah I saw that , but if I do it that way , im racing against time , I feel by the time I get to the end of a 9 ft mal the resin would be going of ? One youtube I saw, they were using a paint which gave them plenty of time to go off?
I have rolled on finish coat epoxy but wouldn’t try it if I were trying to use pigmented resin to cover up an old board, I don’t think you could get it thick enough.
Hi today I experimented , I rolled on a clear filler / hot coat using solarcure to see by quanity how thin it would be, my board only took about 125 mills about, so I figure if I get a litre of gloss coat resin I can build it up in layers till its opaque enough to get some wet and dry onto it then polish? I later sanded the experimented coat off.
If it doesn’t go on thick enough as you say than I can use opqaue suncure which I love using and build it up in layers each layer will be transparent enough to cure in the sun, each layer eventually will make it look darker, I think?
Tons of good stuff on applying a pigmented finish coat in the archives. This is the way that early 60’s boards were pigmented. Not that hard to do, but takes a little bit of time/effort to get the coverage right, and then not to sand through when rubbing out!
Basically like applying a gloss coat.
What you’re seeing with the rolling method is that the roller is for easier uniform application, while the brush is for smoothing it out. Probably works great, never tried it as I am fairly happy with my glossing technique with a brush.
“Waste” a little resin by doing test panels - what looks opaque in a bucket rarely is once is spread quite thin in a gloss layer. And figure out how your tint affects your go-off times, brands and colors vary. Nice and even, hot enough to go off before you get dust and such, but not so quick that it can’t flow out properly. Two layers is do-able, but you’re getting extra weight for you buck!
Again, good reading in the archives and a lot of people who do/have done this much better than I ever have/will.
Enjoy!
