This product is pretty straight forward, you place it where you need it and it seals pretty nicely. I placed it around the wall base and it does pretty good but it seems to do better when I used it on the floor seems. It just seems to level out well on a ground surface.My only wish is that I had it in another color. Don't get me wrong the white color is really bright and stands out after it's in place, but when dirt gets on it, I want to clean it, but I guess I should just let it get a little dirty or dusty, so that it blends in little better. Hopefully, they will add a concrete tone to the collection.It's only been a couple of days but it's still flexible, so that's a plus.Really seems to be a food product!

STANLEY's Self-Leveling Polyurethane Sealant offers a reliable solution for sealing horizontal expansion joints in various outdoor surfaces, from driveways and sidewalks to decks and industrial floors. While it performs admirably in terms of adhesion and elasticity, there are some considerations to keep in mind, particularly regarding its color and application process.Let's start with the sealant's performance. When properly prepared, this self-leveling sealant adheres well to cracks and expansion joints, providing a durable and elastic barrier against moisture and other environmental factors. I've used it on several surfaces around my property, and it has held up remarkably well under various weather conditions, including the scorching sun and occasional rain we experience here in Southern California. Its elasticity ensures that it maintains its integrity even as temperatures fluctuate, preventing cracking or peeling over time.However, one aspect to note is the color of the sealant. While advertised as white, it may not blend seamlessly with cement surfaces as expected. The stark contrast between the white sealant and the gray or tan tones of concrete can be visually jarring, especially on larger areas. If aesthetic cohesion is a concern, it may be worthwhile to explore alternative color options or consider applying a tinted sealant.In terms of application, STANLEY's self-leveling sealant requires careful attention to detail. Proper preparation of the surface is crucial, including thorough cleaning to remove any loose material, dirt, or grease. Once prepared, the sealant can be applied directly from the sausage pack without the need for mixing, which simplifies the process. However, cleanup can be challenging due to the sealant's adhesive properties, so it's essential to mask adjoining areas and apply the sealant with precision to minimize excess.The coverage provided by a single 20-ounce sausage pack will vary depending on the depth and width of the cracks or expansion joints being sealed. For larger projects or deeper crevices, multiple packs may be required. It's worth considering the scope of your project and purchasing adequate quantities to ensure complete coverage without interruption.One of the standout features of this sealant is its flexibility, particularly in accommodating expansion joints. Whether it's a driveway subject to vehicular traffic or a sidewalk exposed to foot traffic, the sealant's ability to stretch and contract with the movement of the underlying surface is invaluable. This flexibility helps prevent the sealant from cracking or becoming dislodged over time, contributing to its long-term effectiveness.Overall, STANLEY's Self-Leveling Polyurethane Sealant offers a reliable solution for sealing horizontal expansion joints in various outdoor surfaces. Its strong adhesion, elasticity, and flexibility make it well-suited for withstanding the rigors of changing weather conditions and structural movement. However, users should be mindful of its white color, which may not blend seamlessly with concrete surfaces, and exercise caution during application to ensure precise placement and minimize cleanup efforts. With proper preparation and application, this sealant provides an effective barrier against moisture infiltration and helps prolong the lifespan of outdoor surfaces.

Neither I nor my contractor friend had ever used a sausage gun, so I decided I would get a sausage gun and try this Stanley one-part self-leveling polyurethane. Slide the sausage into the gun, cut off the tip, and screw the end on the gun. Then it works like a standard caulking gun. The sausage contains about twice as much material as a standard tube of caulk.This material flows easily from the gun, with a bead width that depends on the tip diameter and how fast you move the gun. I love its liquid-like self-leveling quality, but that means you have to seal off the end of the crack (for example, at the edge of the concrete) or it will tend to flow out of the crack. I just used masking tape to seal the joint edges. If you use it on a deck, you may need to tape up the underside of the joints to keep the urethane from flowing out the bottom of the joint. The instructions say minimum depth is 6mm (1/4"), but I ignored that and it still worked fine. Your experience may vary.For good adhesion, you need clean surfaces. I tried blowing the cracks out with compressed air, and it worked OK. Air has the advantage of not needing to dry, so I mostly used air for cleaning the cracks. But air doesn't clean as well as water, but then it must dry thoroughly. (Wet surfaces will cause it to bubble.) With clean, dry surfaces, I found adhesion to be outstanding. No curing time is given, but I like to give it 24 hours.The color of this urethane is bright white, and it stands out against the color of the substrate. For many years, I've sprinkled sand on top of sealants (Urethane, Silicone, Acrylic, doesn't matter) for color matching. I sprinkle sand that matches the concrete, press it in a little, then gently blow off the excess after a few days. I also use dark sand for asphalt. The label on the tube says this material is paintable, so for a deck or asphalt or house flooring you could just use paint (once the urethane has had several days to cure).The sausage gun application system works well if you're going to use large quantities of the same material, so you won't have to change the type of material in the gun. To change to a different material, you have to use up or pull out the old sausage wrapper, try to clean up the front of the gun, and clean or replace the spout. Then you're stuck using the new material until you finish the sausage. I prefer the standard (tube) caulking gun, where you can seal the spout and pull it out, and put in a tube of a different material. I often go into a caulking job with two or more partial tubes of various kinds of caulk, but with sausage applicators, you would need a separate applicator for each kind of caulk.
