bizzard 2402 Report post #2 Posted September 12, 2020 To be honest I wouldn't use a roller for blacking. If you roll at the normal fastish speed it will roll over tiny pits without impregnating them, next day you find them popped and needing brushing in again. Roll very slow or just use a brush. 1 Share this post Link to post Share on other sites
Midnight 269 Report post #3 Posted September 12, 2020 I use a big hairy one but if your hull is pitted you'll need a creosote brush as bizzard suggests Share this post Link to post Share on other sites
Movin' on 300 Report post #4 Posted September 12, 2020 BRUSH every time - rollers don't do the job properly (even big hairy ones 😉) - you only do it every 3 years so its worth doing properly and using more product. 2 Share this post Link to post Share on other sites
TheBiscuits 3768 Report post #5 Posted September 12, 2020 I prefer any roller or brush that has someone else holding it! More accurately, I tend to use a 4" gloss roller with a brush for the fiddly bits. Last time we did 3 boats consecutively with all 3 of us helping each other.

Richard10002 2897 Report post #6 Posted September 12, 2020 The two times I've blacked my hull I've used cheap 4" rollers, after cutting in the corners and hard to get bits with a brush. All pits filled, every bit of the hull covered, 3 or 4 times. Share this post Link to post Share on other sites
blackrose 1620 Report post #7 Posted September 12, 2020 I always used a wallpaper brush for the first coat to get into the pits followed by a couple of coats with a roller. If there's enough paint on the roller and you use a bit of pressure it will get into the low points. 1 Share this post Link to post Share on other sites

All pits filled, every bit of the hull covered, 3 or 4 times. Exactly this. Roll quite slowly so that the blacking gets into all the pits and other unevennesses in the surface.

Don’t use a foam one, they leave air bubbles that burst and can leave bare patches. I used to roller everywhere, then go back and brush into all the inaccessible corners and angles, or brush first then roller afterwards. Rollers work perfectly well, just take your time: brushing is a huge faff and hard work. Rollers and brushes can be left in a bucket of water between coats, btw. The above relates to use of bituminous paints, obviously. 1 Share this post Link to post Share on other sites

Unlike most marinas, who slap it on as quickly as possible- two coats if you are lucky. I use chap 4” brushes, wrap in cling film between coats (good for two or three days) then binned. 1 Share this post Link to post Share on other sites

My post is based on me having done a lot of blacking, always two coats after a seriously fussy power wash with a really strong, hot, jet washer. Share this post Link to post Share on other sites
