Rated 1 out of 5 by from Big nope Maybe I got a defective batch, but everywhere I applied this, it has cracked, literally everywhere. Every corner, top, bottom, along trim, every nook... cracks. I bought this "flex" version because the regular version cracked too. :\

Rated 4 out of 5 by from Worked well for baseboards Really happy with how this turned out with our baseboards. The only issue I've had is that we installed them in summer with high humidity, and unfortunately, the baseboards seem to have shrunk slightly, so it has cracked at the seams, but the seam with the actual wall is still perfect. Would still use this again. Super easy to use.

Rated 4 out of 5 by from Good product. Works well. Careful how large or small you cut tip or product amount will be more difficult to work with. No odour, dries fast. Paints well.

Rated 3 out of 5 by from Conflicted Easy to apply and achieve professional results, looks great. My issue with this product is if you ever have to remove your trim...recently made a change to lower profile base and even when first scoring with a knife this stuff removes the layer of paint AND the drywall paper leaving a loose paper edge that is difficult to skim coat and sand level. Good if you don't plan to change your trim in the future.

Rated 5 out of 5 by from Excellent produit Ça se pose, à mon avis, plus facilement que les autres produits du genre. Petit truc trouvé sur le net : couper le bout en faisant une ouverture la plus petite possible (3 mm est suffisant). Ça limite les pertes et les dégâts. On étend, on repasse avec un doigt et on essuie facilement avec un linge humide. Résultats surprenants.

I will be using this along baseboards and door trim. Some areas will get painted over, some not (ie the seam between the door casing and wall). Will the caulking turn yellow if left unpainted?

Asked by: Matt
I didn't paint ours, just left the primed moulding and it hasn't turned yellow. It's been a year and a half now.

Is this good for caulking around the perimeter of laminate flooring to create waterproof seal? If not, what should I use? Needs to bond to laminate's MDF core and the OSB subfloors to prevent water infiltration under laminate if there is a spill.. Thanks.

Asked by: OurLadysVictory
Thank you for posting your inquiry. We are not clear regarding your intended use of the product, as most laminate floor manufacturers do not recommend bonding the flooring goods to the underlayment/adjoining surfaces (with adhesive or caulks/sealant). At your convenience, please contact DAP’s Technical Customer Service Department at 888-327-8477 so that we can obtain some additional information from you to determine how best to proceed.

Is it sandable?

Asked by: kia salimi
Thank you for posting your inquiry. DAP ALEX FLEX is not sandable (as is the case for all of DAP's flexible caulking/sealants), tooling/shaping/smoothing must be done while the product is still in its wet form. Should you have any additional questions or require further assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477.

would you use this on seam between drywall and shower jam?

Asked by: HomeOwner
Thank you for posting you inquiry. Providing that the ALEX FLEX sealant is not within the shower enclosure, this would be considered an appropriate application. Should you have any additional questions or require further assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477.
