What people are saying about our products
I wanted to send you guys some pictures of a project we did. It turned out really well and your materials performed great. I chose to replicate and mold 3 new pieces of terra cotta from a deteriorated sample piece. I took this on as we were already restoring the rest of the building and I thought it would provide a good opportunity to try and use your materials in a new way. We will definitely continue to use your products as they have proven to provide quality results.

I believe the training was beneficial for both inexperienced and experienced installers. The inexperienced installers were educated on proper application techniques and the experienced installers were re-educated and exposed to the full Conproco line of materials for future usages. Overall I feel the training was a success. I would highly recommend this training class to anyone in the masonry restoration industry. It is well worth the time and money! Thanks Larry!

Excellent training, personally I’d rank it in the top three trainings I’ve ever been to. Excellent instructors and positive critiquing. No question was left unanswered. It provides better insight on production to office personnel when you can see and understand the difficulty one can encounter during something such as a restoration project. Our seasoned installers commented that it was a good refresher course and was useful in reviewing some of the fundamental lessons in patching. It’s great to know there are still companies out there willing to get their hands dirty while providing useful tips and tricks.

Excellent training! This 8 hr class was by far the best training I have been a part of since I started my masonry career 20+ years ago! The crew at Conproco did a fabulous job organizing and performing the training . I also had the privilege to act as the proctor for this training thru SWRI. I would highly recommend it to anyone in or new to the industry! Great job Larry, Kirstin, Aaron, and Don!
