Why does gloss paint wrinkle

Never mind live and learn eh. Thanks anyway appreciate it. More thin coats are better than less thick coats! Robbie uk , Jun 15, You must log in or sign up to reply here. Show Ignored Content. Share This Page Tweet. Your name or email address: Do you already have an account?

Once the area is sanded and nice and clean, you want to hit it with 2 coats of paint and then 2 coats of VHT gloss if you want a nice glossy finish. One cause is by laying down too much material piling on too quick insufficient flash times between coats.

Driving the solvents down into the material. To fix paint wrinkling scrape or sand to remove the wrinkled coating and sand the surface smooth to blend it into the surrounding coating. Spray paint should be applied in multiple thin coats, each of which is allowed to dry completely before applying additional coats. If spray paint is applied in a single heavy coat, the weight of the paint may be too great and the paint will wrinkle or sag as it dries.

If a first coat of spray paint is not allowed to dry adequately before the second coat is applied, the solvents and drying agents in the second coat of paint can compromise the hard shell of the first coat, converting it into a slimy, unstable surface. As a result, the second coat attempts to bond to an unstable substrate.

In this case, the topcoat wrinkles because it loses adhesion to the item's surface. Another reason behind wrinkled sprayed-on paint is surface contamination. For spray paint to dry properly, it must have a clean, dry and properly prepared surface. If the surface is contaminated with a solvent or cleaner film left from the surface preparation steps, that residue can react with the spray paint carriers and cause the spray paint to wrinkle as it dries.

In this case, the paint must be removed and the surface re-cleaned before being repainted.
