Part Numbers Variations: 445805 Review: Tremco Vulkem 45 SSL Sealant - I purchased Limestone Tremco Vulkem 45 SSL One-Part Semi-Self Leveling Polyurethane sealant from ShowerDoor Direct through desertcart to replace wood expansion joints in the terrace around my pool. It took a couple of days longer to arrive that I am used to but was packed very well and arrived in perfect condition. As explained below, the sealant works very well as long as one asks it to do what it is intended to do. It has great adhesion and leveling. After removing the rotted old wood expansion joints, I installed Closed Cell Backer Rod but initially I did not use a wide enough Backer Rod and when I applied the sealant it ran down anywhere that was open and this caused me to waste a large amount of sealant and it is impossible to get it to level properly. Then I got wider Backer Rod and made sure it was level and that there were no openings. Then the sealant worked great. It skins over in an hour or so so you can use it even if it is going to rain later in the day. The final result doesn't show any minor imperfections that one notices as one is applying the stuff because of the leveling quality of the material. It looks very professional and I would recommend it. Please note, however, that this sealant is only for level areas. If you need sealant for anything with a grade, this is not the proper product. Review: Pay attention to the size - One Star isn't really fair as I returned the product before using. This is a gigantic tube. 30 ounces as compared to 10 ounces for a regular size tube of caulk. This WILL NOT fit in a normal caulk gun you have to have a special one. ## Features - Semi Self-Leveling Formula – Provides smooth application without excessive flow - Durable & Flexible – Withstands joint movement and thermal expansion - Weather & UV Resistant – Performs in extreme temperatures and outdoor conditions - Excellent Adhesion – Bonds well to concrete, masonry, and other porous materials ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 3.4 out of 5 stars 14 Reviews | ## Images ![445805 CRL Limestone Vulkem 45 SSL One-Part Semi Self-Leveling Polyurethane - Image 1](https://m.media-amazon.com/images/I/5167iZ-cDlL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Tremco Vulkem 45 SSL Sealant *by N***R on August 10, 2012* I purchased Limestone Tremco Vulkem 45 SSL One-Part Semi-Self Leveling Polyurethane sealant from ShowerDoor Direct through Amazon to replace wood expansion joints in the terrace around my pool.

This is a gigantic tube. 30 ounces as compared to 10 ounces for a regular size tube of caulk. This WILL NOT fit in a normal caulk gun you have to have a special one. ### ⭐⭐⭐⭐ Works as expected, just know what to expect *by J***H on June 26, 2013* So far a great product, it did self level very nicely. My only issue with it was with me, as this was my first use of a self leveling product. Comes out of the tube much thinner than I expected, protecting area's around where you want this product is a must. Great product, will use again. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/18959401-445805-crl-limestone-vulkem-45-ssl-one-part-semi-self](https://www.desertcart.us/products/18959401-445805-crl-limestone-vulkem-45-ssl-one-part-semi-self) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-11*
