Flex Caulk, Waterproof & Weatherproof Hybrid Polymer Sealant, Strong, Paintable, Indoor, Outdoor, Bath, Shower, Sink, Window, Baseboards, Door, RV, Roof, Wood, Auto & Marine, Clear, 6.6 oz, 1-Pack

When replacing a failing under-counter mounted sink (the glue failed), I chose a drop in replacement sink (also reviewed on Amazon), so it won't Halen again (unless gravity fails!).This is the sealant I used you ensure the new sink would not leak around the rim. Other herbal kitchen/ bathroom soft white caulking makes nice edges, but often gives out, needing replaced. THIS stuff is tough, and with a generous ring sandwiched around the sink beneath the flange/ rim, this stuff will both seal and ensure the sink remains firm in place.Of course I added the sink recommended bracing beneath, to ensure the sink stayed in place while the Flex Caulk was drying.This stuff is easy to apply, and not watery like the generic cheap stuff in the hardware warehouse stores. Months after installation, this caulking is firm in place, wipe-able along the sink edges with a wet rag, and "semi-rigid" (flexible yes, but firm in place).

My hubby thought I should wait until he had time to do the job for me but I've used caulk before. This was even easier! Just squeeze the trigger and move along at an angle. There's no smell and no mess. I went along the bottom of sliding glass doors and have plenty left over for other jobs. Definitely worth the money and it really works.

Used it to seal a window that had come loose. Seems to have done the job and was easy to use.

Good on clear, fast drying , works as recommended

Wear gloves. Very sticky.Seems to be working greatNo leaksReally like that it comes with a cap to reseal it between uses

Before purchasing, I read reviews which said this product was difficult to figure out and to use. I had a very different experience. Pull off the red cap with pliers and follow directions on the package or tube.I reinforced some caulking on my camper while standing on a tall ladder. I could not have accomplished this while using a caulking gun, but with this product it was easy, peasy.I will update this post if I experience negative effects, especially if it stays tacky. It v was cold when I applied it (35°) but nothing on the packaging called for certain temps.So far an easy to apply product.

Works well

I honestly dont usually leave a review. This won't be long. I had HIGH HOPES for this product. As you see, it states that its clear. I went around the apartment, and started applying it to cracks and crevices. The next day, I went around the apartment to check the locations where it had been administered....When I tell you "DISGUST" is an understatement- it is. EVERYYY place where this was administered was "YELLOW" My white walls, and cabintes now had dried "YELLOW" residue. Now I have to go to either Home Depot or Lowes to buy SEVERAL different colors of paint(since each room is a different color)to redo my walls 😤
