Why Paint Jobs Fail

LOSS OF GLOSS:

Loss of initial gloss has several causes in the application of paint. On exterior surfaces it may be caused by improper priming. All areas where the old paint has been removed should be spot primed before priming the whole area. This will eliminate the surface porosity, which causes flatting. Also, applying paint in cold, damp or foggy weather can cause dulling of the paint film. Over-thinning paint is also detrimental to a good gloss.

Insufficient drying time between coats causes trouble with gloss. Frost condensing on a freshly painted surface may cause the paint to flatten immediately or start some paints to chalk excessively.

To avoid flattening of fresh paint films, prime properly, avoid unnecessary thinning, clean surfaces thoroughly and paint in good weather, above 50° F.
