Rated 5.0 out of 5.0 by Versatile, terrific product Where would I be without DAP? In the process of restoring an 82 year old house, I've used DAP on exterior windows (replacing panes of glass), interior and exterior gaps and cracks, to fill nail holes, to give that extra-smooth finished appearance to painted moldings. This is a terrific and versatile product; also very reasonably priced, which is important when you go through a lot of it! October 18, 2010
Rated 2.0 out of 5.0 by Do Not Use on Hardie Plank or Similar Siding Maybe on other applications this product may work okay. My experience with Alex Plus was not good at all. I had a similar siding to Hardie Plank Siding. Even on the cooler sides of the house there was shrinkage and cracking in the caulk bead. I ended up going through about four types of caulk before I found one that worked well on this siding. My contractor said he liked using the Alex Plus. Before I could even get paint on it I noticed the cracking in the caulk. So I ended up installing and removing a fair amount of caulk until I could find one that worked.. This type of siding must be able to absorb a lot of heat and cold because the expansion in this cement siding board is so great. September 24, 2015
Rated 5.0 out of 5.0 by SUPERB PRODUCT! RENEWED THE LIFE OF MY RANCH HOUSE!!!! We have an older ranch house and had a terrible time with the 40 year old wood siding having cracks and having cupped and pulled away from the house. These issues allowed all the flies and bugs within miles to migrate into the house for winter hibernation. We had to deal with bugs all fall and winter. We also wanted to repaint the house. We needed a superior product that would seal the cracks and openings caused by the cupping of the boards. We also needed a product that would allow us to paint over it so the new paint job would look good. The product was superb and superior in every way. It blocked the flies and bugs from the house and the paint covered the Alex Latex Caulk. We could not be happier with this product and buy it by the cases. Next project is the barn!!!! Thank you!

Rated 4.0 out of 5.0 by alex plus the alex plus caulk worked very well. It applied with a smooth bead and adhered to vinyl and wood products very well. We have used it in moist conditions (rainy weather) and were quite pleased with the outcome. November 23, 2015
Rated 2.0 out of 5.0 by Great product, avoid the multi pack The Alex Plus caulk itself is a great product. Easy to apply and tool. dries quickly and is paint ready almost as fast as they claim. Trying to save a little money on the multi pack may cost you more than the individuals however. 5 of 12 were dented in and blown out at the bottom. Attempting to straighten and use them proved a disastrous mess. If I need another case I'll open it up in the store before I cart them so I'm not surprised 30 miles from the store and pressed for time. November 3, 2015
Rated 5.0 out of 5.0 by Really great caulk I bought this because I'm cheap but to mu surprise, this product out performs most caulk costing up to three times as much. It goes on easy dries quickly, can be painted. Works outdoors or in. Just great caulk November 3, 2015
