What Customers Are Saying

Customers overwhelmingly praise this caulk for exceptional durability and performance, with most noting it lasts significantly longer than standard alternatives without cracking or deteriorating through seasonal changes. Reviewers highlight its smooth application in cold and wet conditions, strong adhesion to multiple surfaces, and ability to be painted within an hour while drying clear. Many appreciate the thick consistency and crystal-clear finish, describing it as top-tier for exterior sealing. A few customers reported dried-out tubes requiring high-torque guns, though these issues are rare compared to widespread satisfaction.

Great product

I ordered this and picked up at the local Lowes. Excellent adhesion and was able to smooth it nicely. I have heard good things about it and great adhesion. I used it on our travel trailer on the windows, doors and panels.

High quality good for siding and trim

Would Recommend

The quality of the caulking is very good and buying in bulk makes the price work out pretty well. This is the caulk you need for siding and trim and is officially James hardie approved. The color matching is also nice but in my case I just needed plain white. I have trust that this caulking will not crack severely and wish all contractors used this caulk instead of other cheaper caulks.

Super tough stuff when you need a heavy hitter!

Would Recommend

This material stands up to anything and is great. I love the nozzle that unscrews. When partially used, I unscrew the nozzle, put a piece of plastic bag over opening and then screw the nozzle back on. Next time I need it, I unscrew the nozzle, remove the plastic bag piece, and the dried up stuff in the nozzle is removed very easy with needle nose pliers from the large end! Super easy and no sealant goes to waste.

I think the GE brand is better

Would Recommend

I used a lot of this stuff to seal crack inside and outside my house and it has worked great. But I have also tried the high end GE brand sealant, and I think that is better. The GE stuff spreads a little easier, and is easier to remove afterward if you need to.

Works as intended

Would Recommend

Used this product to seal around a sliding patio door and it worked very well. So far no water infiltration and the white was bright and clean. Applies easily.

Best sealant

Would Recommend

Best sealant that Lowe’s carries in my opinion. Keeps things watertight, durable yet extremely strong. Also manufacturer can color match which is nice when your dealing with custom homes.
