Benjamin Moore dealer recomended their 100% acrylic latex primer (fresh
start). They said it was a bonding primer and did not require bonding
additive (emulsabond). I tested it on a small area, brushing it out real
thin and within hours in direct sunlight I could not scratch it off with
with my fingernail. So I went ahead and did a small area (front and sides
of a dormer) but two days later I was able to scratch it off fairly easily,
I was dissappointed. The only difference was that I put it on heavier.
Note: not too heavy, I know how to paint and prime, a nice even coat. I
called BM and they said that I should expect to be able to scratch any latex
coating for at least a weak, maybe up to four weeks. But it was ok to go
ahead and paint. So I put a base coat over the primer and its' been about a
week and I can still scratch it easily. This has not been my experiance over
the years. So I tested an area with BM oil primer and it seems to be
sticking like glue. The oil primer was tested strait and thinned some and
alothough the the thinned drys faster they seem to stick equally well.
Am I making too much of this and just trust BM and go ahead with the latex
primer, maybe thinning with water some?
Should I just bite the bullet and do it in oil?
What do you guys think?
BM recommends against thinning any of their products.
Conditions have been good weather sunny and dry.
I know the siding is clean, I did it myself with TSP and a sponge, rag, and
brush by hand
I tested and area after using a chemical de-glosser (will-bond) and the
results were no better
Paint is BM MooreGuard
