BigG1986 Posted January 25, 2007 Report Share Posted January 25, 2007 (edited) sand down and spray again Edited January 25, 2007 by BigG1986 Quote Link to comment Share on other sites More sharing options...
carousel182 Posted January 26, 2007 Author Report Share Posted January 26, 2007 so should i sand all the primer off and put another coat of sand and sealer on it and then prime it again, like start over completely, or should i just sand it smooth and spray again.

Southpa Posted January 26, 2007 Report Share Posted January 26, 2007 Just let the primer cure and harden up a bit, scuff and shoot more primer. Cover everything, scuff again and more primer if needed or start laying down topcoats. Quote Link to comment Share on other sites More sharing options...

Southpa Posted January 26, 2007 Report Share Posted January 26, 2007 (edited) When spraying primer you really can't make any mistakes. Most primers cure pretty fast. I've been able to sand it after only a few hours when the right drying conditions were available. It helps to understand the function of each finishing component before using it. Primer is basically used to help seal whats underneath and to give a uniform (in texture and color) surface for your topcoat. Its wise to "scuff" the cured surface layer prior to applying the next coat. This makes striations that give the surface some "tooth" allowing the next coat to form a mechanical bond to the underlying layer. There are etching primers, used primarily for bonding to bare metal, and filler primers. Filler primers are what to use here. They have high solid content and are used to build up low spots. Any really low spots like dents and scratches can be drop filled in successive layers. The scuffing is also important to level the overall surface. Use a rigid block for sanding flat surfaces and a foam pad is good for curves 'n corners. You don't need to begin sanding primer with anything coarse, I usually start at 320 or 400 and take it up to 600 or 800 before topcoating. But it depends on how rough or uneven the surface is, the idea is to build up lows and sand down highs until you reach that happy medium.

BigG1986 Posted January 27, 2007 Report Share Posted January 27, 2007 it'll do but as southpa said a "FIller Primer" is normally best Quote Link to comment Share on other sites More sharing options...
