Full cure ~4 hours at +23 °C / +50 % r.h.

The curing time of Sarnacol®-2152 is dependent on the ambient temperature.

Consumption depends on the roughness and absorbency of the substrate and is about 500–1 000 g/m².

Reinforced concrete structure must be:

• Hardened and of sufficient compressive strength, minimum 25 N/mm²,
• With a minimum pull off strength 1.5 N/mm²
• Dry, sound, clean and free of any contaminations (e.g. dust, oil, grease, release agent)
• Free from surface defects (e.g. blowholes, voids, honeycombing, cracks, protrusions)

The concrete or other suitable cementitious substrate must meet the defined substrate quality. If the substrate does not fulfil the requirements, the surface must be pre-treated prior to the application in order to prevent any subsequent damage to the membrane sheets.

Mix components A+B together in the correct proportion into a suitable mixing pail for 3-5 minutes with a low speed mixer until the material becomes smooth in consistency and has a uniform white colour. Avoid aeration while mixing the 2 components.

Mix only that quantity which can be used within its pot life.

Apply membrane on substrate, marking lines for application. Roll up membrane. Apply the adhesive on the substrate with spatula or squegge. Unroll waterproofing membrane on to adhesive, pay attention to the extruded adhesive on both sides and clean up timely, to avoid any pollution to the membrane which may affect the welding. Press membrane surface lightly to make membrane and adhesive contact each other thoroughly. After adhesive is cured, welding can be started.

After application, tools and devices must be cleaned immediately with Sika® Colma Cleaner or SikaForce®-7260 Cleaner. Hardened and cured material can only be removed mechanically.

Hands and exposed skin should be washed immediately using Sika® Handclean Towel or a suitable industrial hand cleaner and water.

Do not use solvent!
