Good roof primer!
This served as a primer for an elastomeric coating, over a weathered modified bitumen roof. It's important that you clean the surface first with a soft wash or light pressure wash to get rid of any accumulated gunk that may block adhesion. But once you've got a dry & clean surface, this stuff sticks like, well, glue. I laid down two coats several days apart. It dried / cured fairly quickly, so I was able to walk on it after 24 hours (after each coat). Rain doesn't seem to hurt it after it's had a few hours of initial cure time. Just get it good and dry before re-coating. I'm now finish coating it with AMES Elastomeric white roof coating, with good results so far.

Not as advertised.
Pretty bad. I bought it to cover plywood rooftop of a walkway I built. I put on one coat and it was still cracking and dried up. I went back over the seams with a thick blob coat and it was still not holding together. It got hard in the sun and dried and cracked. I ended up having to buy sheet metal for the roof because this blue Max didn't do the job. Now I'm stuck with 5 gallon bucket of it and don't know what to do

Pet stained subfloor
I actually used this to seal my subfloors after attempting to neutralize pet stains. The stains were the worst! This product is amazing, easy to use, very easy to clean up. Would use 10 out of 10 for any waterproofing need.

QUALITY UNMATCHED
You are not going to believe how I used this product. I build a whole water tank just with the product. No mortar used. Nice and thick but no pasty. Application easy I used ketchup bottles to spread. I used 2 of them on a cabin roof and painted over for water proofing. If you are DIY. You need this. This is my 8 bucket order.
