Common Questions

Is Laticrete Strata mat waterproof?

STRATA_MAT™ is not intended for use as a waterproofing membrane. Not for wear surface, must be covered with tile. Adhesives/mastics, mortars and grouts for ceramic tile, pavers, brick and stone are not replacements for waterproofing membranes.

What is strata mat used for?

STRATA_MAT™ XT is designed specifically for ceramic tile and dimension stone installations serving as an uncoupling layer and vapor management layer that accommodates moisture from beneath the tile covering.

Questions & Answers
3 questions

I have some Schluter Ditra but want to try Laticrete Stratamat can they both be used for the same tile job? The room is about 30x30 I have a full roll of Schluter Ditra plus some extra footage. Is it the same thickness and similar of same characteristics? Thanks

These two products have very similar properties and are basically the same thickness however consider that you are voiding both manufacturers warranties. The main difference between the two are that Laticrete Stratamat can be used with both modified and unmodified thinset and the Ditra can only be used with unmodified.

Can you use it over plywood?

Hybroban can bond to exterior glue plywood. All surfaces must be structurally sound, stable and rigid enough to support ceramic/stone tile, brick and similar finishes. The installer must verify that deflection under all live, dead and impact loads of interior plywood floors does not exceed industry standards of L/360 for ceramic tile and brick or L/480 for stone installations and L/600 for all exterior veneer applications where L=span length.

Can I use the strata mat over 3/4" advantec, 16" on center glued and screwed?

Please refer to OSB section of on page 2 of the Laticrete Stratamat Manual for installation instructions over OSB & plywood.
