Yeti2300 Posted June 30, 2007 Report Share Posted June 30, 2007 Looking for some assistance in the application of flow coat. Is it best to use a paint spray and if so, what doe we use. The use of a paint brush has been tried but this really seems to be the long way of doing the job. Thanks....Mike Link to comment Share on other sites More sharing options...
stb-tack Posted June 30, 2007 Report Share Posted June 30, 2007 Hi Flowcoat was never intended to be an ext hull finish product, was intended for internal to cover raw fiberglass. If u are using as an ext hull finish u will probably be dissapointed. In saying that you will be able to thin it done using thinners appropriate to the product, but will then need many coats. If external then maybe a two pack of your choice, then gellcoat to finish. Do some research other than this forum, like a shipwright or similair and see what you can find.

REV YUKKA II Posted July 1, 2007 Report Share Posted July 1, 2007 yes you need to use gelcoat not flowcoat. you can mix it with acyton to thin it out the same as you do with paint. you need to use more catalyst in the mix to make it go off. i think! i have never done it myself but my old man has and that is what i am going off.

stranded Posted July 2, 2007 Report Share Posted July 2, 2007 when looking into freshing up an old cat 6 months ago I looked into using gel / flow coat to clean up the hulls. My research descovered that it was more trouble than it was worth. If you are trying to cover a large area consider using polyurethane boat paint. This is what I used and the boat looked great! The brand I used was international (brightside) - easy to spray and thin / clean. If this is not what you are trying to do then ignore my post.

Leapin Leroy Posted July 5, 2007 Report Share Posted July 5, 2007 DON'T use gelcoat externally! It is only un-waxed flowcoat. The un-waxed bit means that it will stay "tacky" on the surface after it has cured! This is so that you can achieve a chemical bond with closely following layer of resin/glass etc... Just thin with acetone or an appropriately endorsed product from the same manufacturer as the flowcoat... Many (2 or 3 sanded in between) thin layers is better than 1 thick 1. Good Luck & hope this helps, Regards, Leroy Link to comment Share on other sites More sharing options...
MikeDean Posted July 18, 2007 Report Share Posted July 18, 2007 Investigating the same subject - got the following advice - which lines up with Leroy's post. This advice from the supplier .... "If you are planning on 1 coat of Gelcoat I would suggest you switch to a White Flowcoat, it costs the same as gelcoat, looks the same, only it cures to a tack free finish. Where as the Gelcoat stays tacky so you can put another coat over the top and will stay tacky for a while until you add styrene wax to the gelcoat. (Flowcoat already has wax in it.)"
