What They're Saying

“We used your F-26® for a waterproof construction project. We have seen zero moisture penetration in any of the areas that have always been problematic. What a great product both from a constructability perspective and performance. If people are serious about building with quality products that get a true return on their construction investment, they need to use F-26® as their construction adhesive. Thanks for continuing the Leech Tradition of Excellence in your products.”
Scott A. WestDirector of Business Development

“Having been a general contractor for over 45 years with 100 million completed commercial and residential projects, I would like to comment on and recommend Leech Products. I use their Wood Filler for oak flooring and cabinet repair. It is the only product that is sustainable and permanent. Great results! No cracking and with care a perfect repair. Also I like F-26 adhesive. No reported failures in 20 years! Thanks for these exceptional products!”

“I have used multiple cases of F-26 Construction Adhesive on projects that glue wood studs to brick walls and sheet rock to studs. I’ve tried other products and they take several days to set up and then still seem soft. I will continue to purchase F-26 only for my projects.””

“In 2001, before a distributor show, I played a round of golf with our rep agency. While playing, the head of my sand wedge flew off the shaft 20 yards in front of me. The next day I was telling the sales manager of Leech Products that I needed to buy a new sand wedge because of what happened the day before. He said that I wouldn't need to buy one because all I have to do is put some F-26 in the head of the club, slide it on the shaft and wait overnight. I did exactly what he suggested and totally forgot about it until the next time I played golf. Before I played I warmed up with the sand wedge remembering that I had fixed it with F-26. Just to be sure I tried knocking the head into the ground to see if it would come off. It didn't budge, and over 15 years later I still use that same sand wedge. F-26 is an truly an amazing product.”
