ive had major problems with all their caulks. anti mildew my ass. and try to get a rep to fix the issues. they laughed and said "we're going to cover the earth and bury you"
god I hope these guys dont buy any more of the local manufacturers or we're screwed
I've even had issues with acrylic inside the house using emulsion. Primarily cracking of the paint. I tried numerous different approaches and times but would usually find some somewhere.
The only suggestion I could make for external caulk would be to wipe it down with some alcohol on a cloth. I'd do a test bit first to make sure it's not a waste of an entire day. Or, use a caulk that's close to the finish colour and apply it over the finish; neat as possible.
We applied the Sher-Max in this video 3 days prior. So plenty of cure time. Sherwin Williams explanation was the high concentration of plasticizers. So what is the amount of cure time before the plasticizers do not affect the top coat? Sherwin Williams does not have an answer so they should have this labeled on the caulking and warn you about this possible issue.
Either way, as you mentioned, huge inconvenience for you and your crew. Was the Shermax applied the day prior or 2 hours prior to topcoat? Thanks for your videos.
Interesting, I have seen similar issues in Oregon with Shermax in cooler temperatures. I noticed Shermax in comparison to Dap's Dynaflex 230 to feel a little thinner when tooling the product out. I think the thinner Shermax takes a little longer to set up, more so at cooler temperatures. Sherwin's Powerhouse, formerly 1100 A has 20% total joint movement compared to Shermax's 70% but has a creamy consistency but still doesn't shrink or crack out. Shermax works awesome most of the time.
You have a good point but Sher-max is far superior to 950a. Sher-max is a Urethanized Premium Elastomeric Sealant and is 75% plastersizers whereas 950a is only 7% I believe. Far superior for adhesion and flexibility. I also think they are all just as workable. Once the temperature rise Sher-max is fine but they need to deal with the issue of it not curing properly in cool climates or take it off the shelf during that time. It is not the warranty I am looking at but the makeup of the product
I never use urethane caulks just for this reason. Acrylic latex primer plus acrylic latex caulking plus acrylic latex paint or stain 100% compatibility. Makes me feel confident I will get the best bond possible.
As an Aussie painter I use Solver acrylic gap filler "caulking". It has proven to be reliable in all temperatures. Cheers heaps for ya tips.

I've always stuck with Superpaint and 950a caulking or 850a in the summer for workability. I think 55 and 45 year warranties are plenty.
Sherwin-Williams is ALWAYS trying to sell me on $omething "new and improved" but I like to stick with the more reliable and well-tested products.
