When applying the gel, is it all done in one 22 mil thick spray?

if you can find a shulz (im not sure of the spelling) its used for spraying thicker viscosity liquids, I use this type of gun for spraying undercoatings and bedliners and I'll even mix resin and spray it that way but you do have to clean the gun in a hurry

Skibum, The spray gun isn't anthing special but it does have to be set up for the gel coat. The fluid tip, nozzel, air cap, etc, needs to be the correct combination for the viscoscity. A gravity feed gun can be used but the problem with this type is it doesn't hold much material so you need to refill it offen. A 2 quart pressure feed gun with remote cup is better. A siphon feed gun can be used but the gel needs to be reduced so much and the air pressure real high to get it through the gun that I wouln't recommend it. The film thickness will be recomended by the gel manufacturer and how much the gel has been reduced but generally is greater than 22 mils. There are film thicness gauges available to check it. If you haven't sprayed much, this is not a job that I would recomend you practice on. Pete

What type of sprayer should I use to apply gel over a large area of the boat? I'll guess and say not an automotive sprayer.
How do I make sure it is the right thickness? Can I apply several thin coats or does it need to be all in one spray? Worse yet, is this something that can only be done at a boat yard because of the extensive amount of equipment and experience required? |
