It once seemed obvious but I’ve forgotten which weight cloth to put down first. I was going to put the 6 oz as a deck patch then cover it in 4oz. Any help? Thanks,Trev
Trev: I like to put the heavier 6oz down first with the 4oz. on top. It always seemed that the the finer weave of the 4 oz would hold less resin in hotcoat (lighter) and would also finish better. There are probably other ways to do it though. Tom S.
Thanks Tom!
I totally respect Tom’s skills as a board maker but I do it different. I cut the 4oz at the rail apex and overlap the 6oz with the idea that there will be fewer sand throughs and a more durable rail. I agree though that there will be more weave to fill with sanding coat. I’m thinking the 6oz weave gets filled anyway during the lam process if doing the 4oz on top, so not sure if weight difference is significant?
Howzit John, I lay down the 4oz first and trim it just above the rail tuck. As for filling the weave, just baste the rails before you hotcoat, makes for less sanding into the weave. Customers really don’t like seeing a lot of weave showing and a basting adds that silly little millimeter of resin which can prevent hitting the weave.Aloha, Kokua
The best way to do it is to do the 6 oz first and the 4 oz. The 4 oz laps down flater. It you hot coat the top and then brush over the bottom lap, and carefully sand the bottom lap, you will have less of a chance of sanding thru the lap. If you do a 6 oz bottom and a 4+6 deck, then I "might"put the six over the four. Only so the 6 oz’s match if you gloss the bottom. You can see waeve patterns after rubbing out…
Howzit Steve, what causes the weave to show is heating up the board when you rub it out, this sets the curing time back. When I do a bit of extra rubbing out in some areas I put a damp cloth on the area and it disappears. It’s a better rub out if you don’t see the weave pattern after it’s done. Aloha, Kokua
It also depends on how strong you want the board. Wrapping 6 oz over the rails will help prevent the board from breaking, and also help cutdown on spider cracks on the rails from banging into things. Remember that 6 oz cloth is a hell of alot stronger than 4 oz, so strength to weight, it is smarter to wrap the 6 oz, unless you are trying to keep the board light. -Carl
Four ounce first with the six wrapping the rail.When hotcating don’t tape the board ,paint up and under the lap line to help fill in the mess.When dry, flip the board,grind down the lap and hot coat it.This is called “basting” around here.If done right you will not hit weave.If you are going to gloss the board any weave that you do hit will turn clear.
