Ideal for use in showers, the product can be applied in other interior and exterior, wet and dry environments. Planislope RS is well suited for a variety of substrates, including concrete, masonry cement block, cement backer units (CBUs), cement and porcelain tile, and adequately designed wood frame floor systems.



Moisture vapor emissions through a concrete slab can contribute to costly flooring failures and significant delays in construction schedules. Maxxon offers several moisture mitigation solutions, including the new single-component Maxxon® Commercial MVP One Primer. It is a ready-to-use, zero-VOC, E96-compliant moisture barrier and primer. When applied to concrete substrates, MVP One Primer addresses moisture-related issues (up to 25 lbs. MVER, 100% RH and a 14 pH) and primes the surface for an underlayment or patch. MVP One Primer has a typical re-coat time of less than one hour, allowing for rapid turnaround on fast-track projects over new or renovated concrete slabs.



Fracture Guard FD is a low-VOC, fast-drying crack isolation membrane specifically formulated by Merkrete for same-day tile installations. Fracture Guard FD provides a thin protection layer to inhibit substrate crack transfers up to ¹/₈ inch. Because Fracture Guard FD is a liquid-applied membrane, it conforms to any shape or pattern, thus allowing endless architectural designs. Used on both residential and commercial interior and exterior applications, Fracture Guard FD exceeds ANSI A118.12 and offers essential crack prevention protection to the finished tile and stone surface.


Miracle Sealants’

Miracle Sealants’ Miracle Heavy Duty Cleaner (Acid Substitute) powers through grout haze, leaving a clean surface that’s ready to be sealed. After applying, leave the solution on the surface for 15 minutes, scrub with a nylon brush, wipe the surface clean and let it dry. In addition to being a key product for new installation, it removes grime and other build-up on existing tile walls, floors, backsplashes and sink surrounds. The acid-free solution is also safe for marble and other sensitive stones.

Mix with Sika Latex R to use as an embossing leveler or patch over properly prepared vinyl sheet goods, vinyl composition tile (VCT), cement terrazzo and residual cutback adhesive surfaces.



USG Durock™ Brand LSP™ Liquid Surface Profiler is a dust-free alternative to cleaning and profiling concrete for indoor, outdoor, horizontal, above and below grade applications. It is the ideal product for preparing concrete for the application of moisture mitigation systems, underlayments, floor patches, sealers and coatings. The patented chemistry of this product is biodegradable, self-neutralizing and low-fume.



wedi Building Panels combine installing tile backer board and waterproofing into one step. Once the panels are secured and seams/fasteners sealed with wedi Joint Sealant, tiling can begin immediately, saving hours (and costs) compared to traditional methods. A 4- x 5-foot building panel was recently added, which helps provide even faster installations with less seams, as well as money savings from using less sealant and fasteners; the 4-foot size safely covers most shower size wet areas fully beyond a curb.
