## Description

Sashco Big Stretch Acrylic Latex High Performance Caulking Sealant, 10.5 Ounce Cartridge, White (Pack of 12)

Review: Best sealant I have ever put on a house exterior - I replaced the lap siding on my house last year and we used 4 cases of Big Stretch White to seal the exposed seams. It applies and is workable as you would expect with any caulk and it was as easy as any other. Filling gaps as wide as 1/2" (possibly more) in one pass was uneventful. + Ability to take paint - Where this stuff really excels is in its ability to take paint. This isn't silicone so its not like its prone to paint failure but Big Stretch doesn't seem to expand and contract in a way that makes the paint chip or crack over time. I have no idea how they manage that, but the painted caulk on my house has held up extremely well. + Bulging and shrinking - I live in a desert so its very hot in the summer and very cold and snowy in the winter. Even with extreme temperatures in the summer Big Stretch doesn't bulge or shrink. The same in sub zero temperatures. I wasn't going to review caulk but this stuff is truly impressive. If you used a lot of caulk in your life and you've struggled haveing to come back over and over to reapply due to shrinking, particularly on exteriors surfaces. This is by far the best product I have ever come across and I have laid plenty caulk (no pun intended!) Sure you can by twice as much cheap caulk for the price but how much is your time worth? Do you really want to be reapplying caulk every year and then touching up the paint.
Review: Many applications for this amazing product. - This stuff is excellent. We used it to cover recessed screw heads on our hardy board siding and after paint you can't see the faster heads. Easy to work with, cleans up easy with water. There is a small amount of shrinkage so over fill the the area. Let dry and trim with a sharp razor blade. It will look amazing! The price was much lower on desertcart than in the big box store.
