APPLICATION
Surface Preparation
Concrete substrates must be clean, dry and free from all foreign matter such as dirt, oil, grease, coatings and surface curing compounds. They must also be sound and have sufficient compressive strength (at least 25 N/mm²), with a tensile strength of at least 1.5 N/mm².
Concrete substrates must be prepared using abrasive equipment to remove cement laitance and obtain an open-textured surface. Weak concrete must be removed, and blowholes and voids must be completely filled. The cleaned surface must be prepared by a suitable mechanical abrasion method such as grinding, sandblasting or sanding to obtain a rough surface.
Concrete or screed surfaces must be primed and levelled to obtain an even surface.
Application Conditions
The moisture content of the concrete must be below 4%.
Relative air humidity must not exceed 80%.
Care must be taken against dew and condensation.
Dew and water-vapour condensation on untreated or newly coated floors may damage the coating and cause blistering. To prevent this, the temperature of the surface and uncured floor must be at least 3°C above the dew point.
Surface Temperature: Minimum +8°C, maximum +30°C
Ambient Temperature: Minimum +10°C, maximum +30°C
Material Temperature: Minimum +10°C, maximum +25°C
Preparation and Application
After pouring Component B into Component A, mix for approximately 2–3 minutes with a 300–400 rpm mixer until a homogeneous mixture is obtained. To ensure complete mixing, transfer the materials to another container and mix again for 1 minute. Avoid overmixing to minimise air entrainment. Before application, confirm that the surface moisture content is below 4% and that no condensation will occur.
As a Primer: EPOFLOOR PRIMEL Q 110 must be applied by trowel or brush. Ensure that the entire surface is covered without gaps.
For all applications in warm ambient or weather conditions, the A+B mixture must be divided into smaller quantities to prevent the risk of premature setting.
As a Repair Mortar: After Components A and B have been mixed, aggregate (silica sand) is added to complete the mixture.
