Surfboard Glassing Schedule

How to glass a surfboard? Glassing is an important step in which some layers of fiber glass cloth are applied to the surfboard. There will be 3 layers of 4oz or 6oz totally applied to the board, usually two on the top and one on the bottom.

First you need to pour 2/3 resin in a pool down the center of the surfboard. Then moving this resin out to the edges with your squeegee. Please move the resin but not scrape it so the fibreglass cloth remains impregnated enough. When the top is wet out, pulling the resin down from the stringer to the edge.

Look at the sides to check if there are any spots of glass cloth that still seemed white. If so, use the leftover resin in the bucket as needed to fully saturate everywhere on the board. When the whole board is wet out, remove pooling on the deck by your squeegee.

Remember that you have to work fast and don't spend to much time on details. And please stop once the resin begins to jell.
