Moisture Mitigation Systems

Sikafloor®-81 EpoCem®

Sikafloor®-81 EpoCem®CA is a three-component, solvent-free, odourless, moisture-insensitive, water-based epoxymodified cementitious, fine textured mortar for self-smoothing floor screeds. Specifically formulated for levelling and structurally reprofiling on damp, green or saturated surface dry concrete slabs at an applied thicknesses ranging from 3 to 4 mm (120 to 160 mils).

Use

As a Temporary Moisture Barrier (TMB), minimum thickness 3 mm (120 mils), allowing the application of epoxy, polyurethane and PMMA resin floors requiring dry substrates, over high moisture content substrates, even green concrete or saturated surface dry concrete slabs, for a lasting solution.
As a Permanent Moisture Barrier (PMB), minimum thickness 3 mm (120 mils) must be sealed with Sikafloor®-1610 or Sika® MT Primer moisture tolerant epoxy coatings to form a permanent low permeability moisture barrier ~0.1 Perm when tested to ASTM E96 / wet method.
As a self-smoothing screed for levelling or patching horizontal concrete surfaces in new construction or refurbishment projects, typically applied under epoxy, polyurethane and PMMA floor coatings / screeds, waterproofing membranes, tiles, sheet flooring, carpet or wooden floors.
Extended with quartz sand, as a patch and repair mortar for thickness of 6 – 200 mm (1/4 – 8 in)

Characteristics and Advantages

Water-based, solvent-free and odourless.
Can be top coated with resin based floors after 24 hours (+20 °C (68 °F) 75 % RH).
Prevents osmotic blistering of resin based coatings over damp concrete substrates.
Economical structural resurfacing compound that is fast and easy to apply.
Good levelling properties.
Impervious to liquids but permeable to water vapour.
Good adhesion after long term water immersion.
Excellent adhesion to dry, damp, green or saturated surface dry concrete substrates.
Thermal expansion properties similar to concrete.
Excellent early and final mechanical strength.
Ideal preparation for smooth surface finishes
Will not corrode reinforcement steel.
Potential LEED® Canada credits
Meets the requirements of CFIA and USDA for use in food plants.

Sikafloor®-82 EpoCem®

Self-Levelling, Epoxy-Cement Floor Topping for Structural Resurfacing

Use

As a self-levelling mortar for reprofiling and resurfacing concrete surfaces, thickness varying between 4 – 7 mm (160 – 280 mils), before the application of:
Appropriate Sikafloor epoxy or polyurethane resin-based products.
Polymer floor coatings.
Waterproofing membranes.
Tile, carpet and wood-floor bonding systems.
Other authorized finished flooring systems.
Ideal vapour barrier for subsequent coatings.
Can be used as a patching and repair mortar for thickness of 6 – 200 mm (1/4 – 8 in) when extended with oven-dried silica sand.
As a temporary moisture barrier, minimum thickness 4 mm (160 mils), prior to subsequent flooring systems on damp, green or saturated surface dry concrete slabs.

Note: Sikafloor 82 EpoCem^CA must be sealed with a suitable Sikafloor epoxy coating to form a permanent vapour barrier. Contact Sika Techical Sales for a recommendation.

Characteristics and Advantages

Economical, structural resurfacing compound.
Water-based, solvent-free and odourless.
Self-levelling and good flowability.
Can be overcoated with epoxy resin compounds after 24 hours [20°C (68°F)].
Application possible on damp and green cement-based substrates.
Waterproof, yet permeable to water vapour.
Fast curing and high early strengths.
Excellent adhesion to dry, damp or saturated surface dry concrete substrates.
Modulus of elasticity and coefficient of thermal expansion comparable to concrete.
Good adhesion after long-term water immersion.
Will not corrode reinforcement steel.
Ideal preparation for smooth surface finishes.
Canadian Food Inspection Agency acceptance/USDA acceptance

Sikafloor®-1610

Sikafloor^® 1610 is a two component, high solids yet low modulus and low viscosity, epoxy primer. This resin is highly penetrative, seals substrates, contains a red trace dye to allow coverage to be ensured and is of low-VOC content. Sikafloor^® 1610 NA has been especially formulated to operate as a moisture tolerant adhesion promoter beneath Sikafloor^® , Sikaguard^® and Sikalastic^® epoxy and urethane coatings, broadcast or trowelled systems.

Use

Designed for concrete substrates where Sikafloor^® resin systems are due to be installed and a measured moisture content of < 6% (p.b.w. – part by weight), as determined with Tramex^® CM/E type meter, exists.

Characteristics and Advantages

Ease of application.
Moisture tolerant.
Excellent penetration.
High bond strength.
Low tensile modulus.
Higher tensile elongation.
Potential for LEED® Canada credits.
Meets the requirements of CFIA and USDA for use in food plants.

Sikagard®-75 EpoCem®

Epoxy/Cement, Resurfacing and Pore-Filling Mortar

Use

For resurfacing 0.5 – 3 mm (20 – 120 mils) thick:

On green or damp concrete, mortar and stone.
As a thin-film sealer coat for vertical and horizontal surfaces.
As a temporary moisture barrier prior to the application of polymer coatings
