fiberglass backing? or sides only?

I am confused on where and how to fiberglass the sides of a project. Do you also put resin on the backing of the project or just the side?

On the picture shown in another thread(shown below), is the correct way to put resin on the same side as the staples are on? or do you just put resin on the very edge of the project but not on the bottom side?

Also if you havea project that has a fiberglass side(instead of wood side like the bottom of this project where the staples are) do you only put fiberglass onto that edge or do u wrap it around to the bottom?  Like instead of using wood on the very bottom of this project, if you used wood would you wrap and resin the fleece to the bottom side or would you trim it so its not on the bottom side?

on these picture will illustrate what im talking about.  I see that he put glass and resin all over but do you flip it over to put resin on the fleece that its sitting on(That doesnt have any on it, the stuff thats stretched around to ghold it in place till it everything is glassed) or do you leave that party dry and just cut it off when the top part is dried/cured?

OOOHHHH!!!

That depends on how you want to finish onto the edges. If you are trying to blend where the cloth meets the wood, here is a technique we use at the shop.

For the side of the wood that is on the outside (in the case of your picture, the bottom) cover it with 3 layers of masking tape and come off the edge a little bit. Then take 50 grit sand paper and sand in a downward stroke at the edge of the wood. This will make a VERY slight bevel and trim the tape down to perfect flush with the edge of it.

Stretch your cloth (preferably polyester) and staple it to the wood. Use 5/32" staples if you can. 1/4" will work too if you do not have 5/32 available. Apply your resin to all parts of the cloth including the wood side. Make sure you also cover your staples too with the resin. That will make removing the excess MUCH easier later in this mini-tutorial.

Let the resin fully cure.

Now take a power sander (preferred over lots of elbow grease) and CAREFULLY grind the edges where you taped and sand-cut earlier. Take it down only to where you meet the tape. DO NOT catch the wood or you will have repair work to do. This will separate the glass from the excess.

With a thin flathead screwdriver, gently pry on the excess materials still stapled to the wood. This is where if you resining the staples and using the 5/32" staples to hold the cloth really becomes truly appreciated. The resin will hold on to the staples as you pry it away and give you a very clean edge that you can blend from wood to glass with little to no evidence.

Now there are several techniques to achieving your goal. It is a matter of what finish are you looking for and what/how you want yout final piece to look like.

Ganbatte ne!
