MAPEI Mapeguard UM 35 Uncoupling, Crack-Isolation, and Waterproofing Membrane
Mapeguard UM 35 uncoupling and waterproofing membrane
Mapeguard UM 35 is a high-density polyethylene (HDPE) uncoupling membrane with a polypropylene fabric backing designed for installing ceramic and stone tile. It provides crack isolation, waterproofing, and vapor management over challenging substrates like young concrete and single-layer plywood subfloors.
Key Features:
- Multi-Function Protection: Uncoupling, crack isolation up to 1/8 in (3 mm), waterproofing, and vapor management up to 25 lbs MVER and 100% RH
- Durable Construction: HDPE sheet with polypropylene fabric backing delivers excellent mechanical and compression strength
- Low-Profile Design: Just 1/8 in (3 mm) thickness to minimize floor height buildup
- Installer-Friendly: Circular cavities allow easy troweling; lightweight and holds a chalk line
- Versatile Substrate Compatibility: Suitable over concrete, young concrete, existing non-cushioned resilient flooring, ceramic and stone tile, and single-layer 3/4 in plywood (joists up to 19.2 in OC)

Frequently Asked Questions (FAQ):
Q: What substrates can Mapeguard UM 35 be installed over?
A: It can be installed over concrete (including young concrete), single-layer 3/4 in plywood subfloors with joists up to 19.2 in on center, and existing non-cushioned resilient, ceramic, or stone tile.
Q: How much crack isolation does it provide?
A: It helps protect tile installations by bridging in-plane substrate cracks up to 1/8 in (3 mm).
Q: Is Mapeguard UM 35 waterproof?
A: Yes. When seams and penetrations are properly treated, the membrane provides waterproofing for wet-area installations.
Q: What is the thickness of the membrane?
A: The membrane has a low profile at approximately 1/8 in (3 mm) thickness.
Q: Does it help manage moisture vapor?
A: Yes, it manages vapor pressure up to 25 lbs MVER and 100% relative humidity.
Elevate Tile Installations with Sculpted, Seamless Confidence
This membrane creates a refined foundation, quietly delivering strength beneath stone and porcelain. I love the subtle, circular texture—an architectural detail that whispers performance while keeping profiles slim. Pair it with expansive marble-look tiles to achieve a gallery-worthy floor that feels effortless. It’s a discreet essential for luxurious living where durability meets design.
