Our recommendation would be to use the Laticrete system with the Laticrete boards.  The problem that arises when mixing these systems is that there is no testing done for the combination. It’s hard to say that it would work or that it would not work. I would highly recommend to stick to one system. This way you would benefit from the warranty and know that the system works.Please do not hesitate to contact us if you have any further questions or require any additional help at 800-709-0002 or by email at orders@contractorsdirect.com
