A:  Can't think of a reason why you would want to sand either standard or elastomeric type caulking but if the purpose is to lightly scuff it up to prepare for a fresh coat of paint, I see nothing wrong with using 240 grit sandpaper and "very lightly" sanding this product - although I professionally would not do it. I'd rather cut it out and apply a fresh coat of a real trim sealant that doesn't crack, like the DAP Dynaflex 230 - rather than use this product. Once dry, you're all set and ready for paint or to leave as is.

A:  no, of course not. it's a flexible caulk. this topic is in the Q&A section.

A:  Yes, I've used this product to fill gaps in moldings and sanded it before painting.

A:  Thank you for posting your inquiry. DAP Alex Flex is designed, marketed, labeled, and recommended for use as a general-purpose trim sealant. It is not designed, tested, marketed, labeled, or recommended for use as a primary construction adhesive.

A:  If you want to stick with this line of caulk/sealant, my advice is to spend another buck or two and go with the Dap Dynaflex 230 or better yet, the Dynaflex Ultra products. They're far superior in 'holding power' and I've emptied cases of this stuff on all types of projects. Never let me down yet. I do have to say, I'd likely look at one of the Loctite adhesives for this project, though. Coupled with a few pin nails as appropriate, you should be in good shape. I wouldn't rely on the adhesives/sealants alone, especially in a moisture rich environment like a bathroom.

A:  Yes, as long as you make sure you have clean surfaces for it to adhere to. I have installed some exterior trim with barely a mechanical connection, very small pin size finishing nails, and secured to smooth surface siding and rough sawn cedar timbers on the other surface to lock it all in place. A great product and well worth the money in the long run.

A:  The painted finish is bright white. I've used it around window trim and have not needed to paint over it.

A:  Thank you for posting your inquiry. While DAP ALEX FLEX does not require paint to be applied for performance, the application of a high-quality paint can improve its overall performance, as the paint will offer additional protection to the applied sealant. The issue that you describe, "dirt pick-up", it typically associated with high performance sealants, such as silicone. These. Sealants with high elasticity will generally have a softer/tackier feel, which can result in the issue that you observed. Should you have any additional questions or require further assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477.

A:  Hi JBL, Unlike a 100% silicone based product, these latex elastomeric based caulks don't attract and hold lint and dust anywhere near as much. The cured surface is far less "rubbery" and allows for much easier cleaning.

A:  Yes, perfect use for this sealant.

A:  Thank you for posting your inquiry. As a general rule, most LVP (Luxury Vinyl Plank) manufacturers recommend the use of 100% Silicone for this application. Of note: 100% silicone is not soap and water clear-up or paintable.
