Laying fiberglass matting for roof

Laying fiberglass matting is commonly compared to wallpapering except that you simply place the paste on the wall, roll out the paper and paint a lot of paste on prime of the paper.

If laying 450g fiberglass chopped strand mat, the right coverage is regarding two litres per square meter in my opinion ( or simply below ). If you follow this recommendation you ought to realize it to be a smooth operation. don't skimp on resin, this makes it tougher work as you roll backwards and forwards many times attempting to unfold the resin out, skimping will increase the probabilities of pinholes and dry spots.

 

Consolidate the Chopped Strand Mat – once a few of minutes you may notice the matting changing into see through, this is the resin breaking down binding agent which holds the fiberglass strands along, this is often precisely what you're looking for. It‘s time to consolidate.

Contrary to the excellent recommendation given by your GRP provider, you'll be able to push resin through CSM(Fiberglass Chopped Strand Mat) matting and find an ideal waterproof end, and what’s more i might say there are times once this can be a preferred method. for me this can be on small bay roofs with intricate detail sort of a multipart bay window.

Less chance if spillages, flicking resin and get away onto surrounding glazing, UPVC or brickwork. ( use a fin roller to consolidate for constant reason )
Matting will be adjusted for correct match 1st instead of placement onto a wet deck, generally during a blustery wind.

Less likelihood of catching the face of overhanging soffits, guttering, or tiles. These are typically contaminated with dirt or hydrocarbon, which may then drop onto the wet roof deck if disturbed.

large roofs – for example. > 50m2 single 600g or possible 450g chopped strand mat double laminate for walkways.

OVERLAPPING FIBERGLASS MATTING AND JOINTS

CSM matting -Fiberglass Chopped Strand Mat– Overlap the matting 50mm to 75mm , and then lay the feathered edge of the matting on top of your last run if potential, this may help the design of visible edges on the joints while the roof is completed. feather edges is only for aesthetics and can not alter the strength.

Pulling at fiberglass mat

Feathering a CSM(Chopped Strand Mat) edge – If you haven’t got a feathered edge however you would like one, simply pull firmly at the edge of the matting and it'll break away in your hand, or rip the matting rigorously on a cut line.

ALIGNING THE MATTING AND laying THE LAMINATE

Have all of your matting pre cut and prepared to travel, roll out a run of fiberglass mat and certify it’s sq. and aligned how you would like it. after you recognize its all OK, roll it back up once more and store it on the roof or floor therefore its simply accessible later.

Setting out the mat. coming up with your escape – continuously think about where you'll exit the roof, you don’t wish to laminate yourself into a dead finish.

Three Main Fibreglass Materials

There are three main fibreglass materials: fiberglass cloth, fiberglass chopped strand mat, and woven roving. I didn't ever use woven roving because it’s used for very heavy duty work. I use mat for build up material, usually while attempting to mate 2 pieces at a ninety degree angle. I then put fiberglass cloth over the mat to build a smooth end.

Using associate additive is a smart plan, no matter what kind of fiberglass material you’re using. Fibreglass microfibers and mixture silica fill in gaps in the materials, offering it less brittle and considerably stronger.

Finally, fiberglass chopped strand mat is designed to wet out with polyester resin and contains a tougher time wetting out properly with epoxy resin. Making your resin thicker with the additive makes it additional time to soak into material. These are hard won fibreglass techniques that I use to do fibreglass properly.
