Nate197 Posted May 8, 2010 Report Share Posted May 8, 2010 Currently, my box for two Fi BTL 18's is flexing a little bit in one area near my port.(I have bracing but no fiber glassing) I want to build a new enclosure in the near future and am a little confused with the steps of fiber glassing the inside of a box, I am not talking about fiber glassing a cloth on the outside. Do I just put the material in place and then resin over? Is their a certain caulk that I should use when using fiber glass? Can I paint over the fiberglass or do I need to apply something else? If someone could please answer my questions I would greatly appreciate it because I want to start building a newer stronger enclosure.

Nate197 Posted May 8, 2010 Author Report Share Posted May 8, 2010 I plan to do a new build in a few days does any body know the steps to fiber glassing the inside of a box and what brands for fiberglass and resin (or any other materials necessary)do you use?

Thanks Nate Cut fiberglass into squares- it makes it easier to apply. Mix resin, spread on the inside of the enclosure. Put the mat over the wet resin. Put more resin over the cloth, and wait. you want to make sure the fiberglass is SOAKED for highest strength. And caulk? lol the resin will seal teh wood. As far as brands... any will do. the more expensive resins spread easier and stuff but the stuff from napa or other automotive stores works just as well.

Nate197 Posted May 8, 2010 Author Report Share Posted May 8, 2010 One more question is their any way that my bass could break the fiberglass and blow particles out of the port? Quote Link to comment Share on other sites More sharing options...

As far as brands... any will do. the more expensive resins spread easier and stuff but the stuff from napa or other automotive stores works just as well. using more resin WILL NOT make fiberglass stronger. the mat/cloth fibers in layers is what gives the glass its strength. you dont want to oversaturate. as long as the glass adheres to the box well, theres no reason for it to break...unless you build the box too weak and theres a significant amount of flex with no strength to the glass; then I could see it cracking over time. but it has to be flexing pretty badly Quote AA-Atomic-Clif Designs-DC-Diamond-Digital Designs-Directed-Eclipse-Fi-Hertz-Hifonics-Kenwood-Memphis-Phoenix Gold-Pioneer-PPI-PSi-Stinger-Sundown-TC Sounds-Viper-Zapco Link to comment Share on other sites More sharing options...

BUT, any dry spots in glass will be weak spots. Seeing as how glass has a thickness and you really don't know how much resin penetration you have, its best to soak it, squeegee it, do whatever you have to make sure that the fiberglass is thoroughly wet. I use it in aviation to fix interior pieces and the number one problem we have is when people have dry spots in the glass. The fiberglass will not crack and blow out of the port. lol. Once its bonded to the wood its not going anywhere. The fiberglass to wood bond should be stronger than the wood to wood ones.
