Q: What is gel-coat?
A: Gel coat is a specially formulated polyester resin that is applied on the mould face. Designed to give good appearance, colour, water and weather resistance.
Q: What is the difference between flow coat and gel coat, can either be sprayed to produce a water tight finish?
A: Flow coat is a gelcoat, with a wax in styrene additive for use as a top coat. Gel coat can be sprayed providing that it is "spray gel coat" not hand lay gel coat. Both gel coat and flow coat will give a watertight finish, providing it is used in conjunction with a fibre glass lamination.
Q: One 'how to' book I have says only spraying gives an acceptable gel coat finish. Another says application with a paintbrush will give satisfactory results, but thickness must be controlled. Which is correct? Are there different types of gelcoat for spraying and brushing? How do I know how thick the gel is if I brush it on?
A: Both brushing and spraying the gel coat give an acceptable finish within a mould, unless you intend to use clear gel coat with a metal or decorative back up. In this case a spray is necessary. I suggest that you coat over twice with gel coat, allowing the first coat to harden. There are different gel coat available, depending on whether you are brushing or spraying.
