Answer for Primers

Exterior primers are more flexible than interior primers and have better binding resins. Generally, interior primers are harder but sand easy. Dave is right, go with a good universal primer (interior and exterior), can't go wrong with that combo.

Answer for Primers

Generally speaking, exterior primers have a built-in moisture barrier where as interior primers do not… however there is much more in the way they are formulated… which only a paint chemist could explain…

For example Pigmented Shellac Sealer Primer is excellent for interiors and does provide a moisture barrier but does not hold up for exteriors…

Regular Latex interior primers do not provide any moisture barrier … the same is true for some interior oil primers…

It's best to use a product that qualifies as both and is oil based… Kilz makes one like this… along with Zinzer Cover Stain…

At last… read the product labels…
