GacoFlex LM60

GacoFlex LM60 is a cold-applied, one-coat, monolithic waterproofing membrane for various surfaces. It’s a 100% polyurethane, solvent-free, liquid-applied, two-component coating. GacoFlex LM60 is easy to use — single application with a squeegee, trowel, spray, or brush.

Why Gaco Polyurethane Waterproofing Membrane System

Polyurethane coatings offer high resistance to water permeability and excellent adhesion to clean, dry plywood and concrete*. However, you may need to apply a primer for other surfaces.

Urethane coatings have high tensile strength, durability, and chemical resistance. These characteristics are crucial for between-slab or below-grade structures where waterproofing membranes must function without maintenance for many years. 

Polyurethane liquid-applied waterproofing systems are used in many applications and have been trusted by waterproofing contractors for over 45 years.

*Application on concrete requires primer. For full installation and product needs, always refer to the appropriate specification which can be found at gaco.com/documents/#specifications.

Benefits

Quick and Easy to Apply – You can use GacoFlex LM60 to waterproof concrete, metal, and plywood in a single application with a squeegee, trowel, or brush. It requires minimal prep work and doesn’t need reinforcement, making the installation process straightforward.

 

Creates Monolithic Waterproof Membrane – If GacoFlex LM60 is correctly applied, your structure will receive a seamless, impermeable elastomeric membrane, protecting it from water damage for a long time.

 

Innovative Solvent-Free, 100% Polyurethane Technology – No odor and VOC vapor, and 100% polyurethanes don’t lose wet film thickness (“WFT”) and dry film thickness (“DFT”). 

 

Cold Applied – There is far less room for error when using cold-applied, liquid waterproofing membranes than hot-applied rubberized asphalts. Less skill is required, and there is a significantly lower chance of moisture evaporation that can cause blistering or pinholes during the installation. 

 

45-Year Proven Track Record – GacoFlex LM60 has stood the test of time. It has successfully waterproofed millions of square feet of horizontal and vertical surfaces on some of the most sophisticated and aesthetically demanding buildings.

 

Warranty Up To 20 Years – Gaco offers a material and labor warranty for up to 20 years on GacoFlex LM60 liquid membrane systems when applied according to Gaco specifications.

 

VERSATILE APPLICATION:

 

Between-Slab or Below-Grade Structures – It’s challenging to reliably waterproof below-grade structures. Buildings can move, undergo fatigue cycles, and expand and contract. Maintaining waterproofing integrity is difficult, especially in cold temperatures. 

However, GacoFlex LM60 does not shrink or crack and has proven its reliability time and time again, even in challenging applications. GacoFlex LM60 can sustain 300% elongation (ASTM D412) and it’s rated at -50 °F (-45 °C) for a low temperature brittleness (ASTM D746). 

 

IRMA Roofing Systems – GacoFlex LM60 is ideal for waterproofing flat or low-sloped concrete or plywood roof decks as a part of an Inverted Roof Membrane Assembly (“IRMA”), also known as an “upside down” roof. First, GacoFlex LM60 is applied to the concrete and allowed to cure. Then, polystyrene boards are placed over the membrane to protect it and provide thermal insulation, followed by a layer of filter fabric and ballast rock or concrete pavers to hold it all in place. 

 

Vegetative Roofs / Garden RoofsVegetative roofs help keep your building cool and are environmentally friendly. They help control stormwater run-off and make attractive outdoor amenity spaces. But, not every waterproofing coating is safe for biodiversity.

 

Tanks, Planters, and Podium Decks – Use LM60 for horizontal and vertical waterproofing of unique structures such as tanks, planters, and podium decks, and better managing the flow of water around them.
