Sika SikaGard 720 / SikaFloor 81 Epocem Part A 1.07kg Moisture Barrier

Sikagard 720 EpoCem

Sikagard-720 EpoCem is a 3-component epoxy-modified cementitious sealing and levelling mortar, suitable for application to most mineral based substrates. It's specific balanced formulation ensures that the properties of the hydrated cement are both complemented and enhanced by the integral epoxy mortar.

USE

Used on both vertical and horizontal surfaces of concrete, mortar or stone, the thixotropic mortar can be applied as a thin layer coating, 0.5 – 2 mm thick or as a scraping/levelling mortar to fill in blow holes, shallow honeycombing and other surface irregularities. It's ability to provide a temporary moisture barrier provides an ideal substrate for subsequent epoxy coatings.

CHARACTERISTICS AND ADVANTAGES

• Waterproof yet permeable to water vapour, allows the substrate to "breathe".
• Excellent bond to green or hardened concrete whether damp or dry
• Fast and easy to apply to sound prepared substrates.
• Solvent free and virtually odourless.
• Ideal surface preparation with the minimum of delay for the subsequent application of other appropriate Sika epoxy products.
• High abrasion resistance.
• Free of chloride.
• Similar thermal and elastic properties to concrete.
• Good adhesion after long-term water immersion
• Suitable for interior or exterior use.

Sikafloor-81 EpoCem

Sikafloor-81 EpoCem is a 3-component epoxy modified cementitious self smoothening floor topping and moisture barrier.

USE

As a moisture barrier (2 mm thick) for epoxy and polyurethane floors.

As self-levelling topping of 1.5 - 3mm thickness for:

• Levelling or patching concrete surfaces, both unfinished and after grinding or scabbling.
• Coloured EpoCem floors on non ventilated damp substrates with low aesthetic considerations (ask for technical assistance)
• Floor toppings beneath epoxy protective coatings.
• Self levelling toppings that are to be covered with polymer floor coatings, carpets or wooden parquet.
• Repair and maintenance of vacuum concrete floors.

CHARACTERISTICS AND ADVANTAGES

• Can be top coated with resin based floors after 24 hours (+20ºC, 75% r.h.)
• Prevents osmotic blistering of resin based coatings over damp substrates
• Excellent bond to green or hardened concrete whether damp or dry
• Waterproof yet permeable to water vapour, allows the substrate to "breathe".
• moisture barrier (7-10 days).
• Self smoothening – good flowability.
• Easy to apply to sound prepared surfaces.
• Solvent free and virtually odourless.
• Ideal surface preparation with the minimum of delay for the subsequent application of other appropriate Sika epoxy products.
• High abrasion resistance.
• Free of chloride.
• Similar modulus of elasticity and coefficient of thermal expansion to concrete.
• Good adhesion after long-term water immersion.
• Excellent mechanical strength.
• Excellent resistance to water and oils.
• Will not corrode reinforcing steel.

COLOUR
