There are many methods for getting the resin
to the fabric, but the easiest I've found so far is to use that piece of wood I had you find in the setting up section. When starting off, Iíll get a decent amount of resin on my brush and paint a decent-sized section of the wood/cardboard. Iíll then take my first piece of mat, and lay it on the section I just ďpaintedĒ, and continue to tap the piece of mat with my brush until the ENTIRE piece is fully saturated with resin. It is then ready to transfer to the project. At this point, hopefully your brush isnít still loaded with resin, because youíll want to use the brush to tap out any bubbles, starting in the center of the piece. Some use a roller, some simply prefer to use their brush to tap out the bubbles, and form the piece.
Make sure to keep the stray end pieces firmly pressed down. If they pop up, and you move on, they may set up, and give you headaches. Once they've set up (hardened), you either have to wait until the entire area can be hit with a rough sand paper to knock them off, or cut off with a knife. If they're not taken off, they will most definitely cause a decent-sized air bubble. Be careful when trying to press these strands down that you don't add too much resin to the structure.
If possible, it is best to do quite a bit at once. Even multiple layers at once. When applying multiple layers before the resin has completely set up make the structure stronger, because the layers are mixed. Also keep in mind though, the more layers you do at one time, the more heat you create, which can and will cause warping if you're not careful!
Also, keep in mind that once the fabric is saturated, adding more resin does NOT add any strength. In fact, it weakens it. Resin by itself is brittle, and adding excess resin will make the structure brittle. Too much resin also separates the layers of glass, which is not good.
Forming the mat/cloth is something that is learned. Expect to get kind of messy the first time. Watching someone who knows what their doing is very deceiving! Learning how the glass stretches and forms just takes practice.
Bubbles are bad! They are weak spots in your structure. If you encounter a bubble, after the resin is dry, sand it or drill it, so you can fill it with resin on your next layer.
Also take note that if you're laying up on foam, that some resins can melt it.
