Exterior Painting Estimates...need advice!
1-Given we have stained shingles, what's best practice for new coating, stain or paint? Pros/Cons to either approach?
(*short of other extenuating circumstance...it's possible yours is one)
2-Since at least a 3rd of the shingles need replaced (don't ask), should the primer be different on the new wood as opposed to the treated shingles?
That depends on what primer and coatings are being used
Usually primers aren't use for stains
3a-If we go the stain route, what type of primer & stain (oil, latex) is best practice?
Oils will last longer, but have slightly more of a chance of growing mold
As always, it's a trade off
Oils aren't mold farms
Latex won't fall off in 6 months
3b-Also, we have a choice between Ben Moore & Cabot stain, any recommendations?
Either/Or...it's a toss-up with those two
4a-For trim (and painting route), 1 contractor quotes with Ben Moor-Guard, the other with Aura. Is there a specific difference in quality (or is it just marketing hype)?
MoorGard is an excellent choice
Aura is better
Specifically it is more washable, burnish resistant, fade resistant, and of course it's more environmentally sound
I suspect it will also prove to be much longer lasting and more mold/mildew resistant...but if you check my location, you'll see I have a good testing grounds for that....I'll have to wait till next year to say for sure
(it's not been out for a year yet)
4b-If there is a difference, is it 'acceptable' to ask the other contractor to use other paint (Aura seems to take some skill in applying).
You can ask
Some don't care for changing their ways or trying something new
Honestly most contractors I know that have tried it have been very enthusiastic about it
(which is kind of surprising actually....mostly we are rats in a maze and we hate it when someone moves our cheese)
