INSTRUCTIONS FOR USE

Surface preparation

Mortar and concrete must be at least 28 days old (depending on the minimum required strength).
Check the surface strength of the substrate (concrete, mortar, natural stone).
The substrate surface must be clean, dry or damp (but not standing water) and free from contaminants such as dust, grease, existing coatings or surface treatments, etc.
The steel surface must be derusted, thoroughly cleaned, and carefully prepared to achieve the desired quality, by using high-pressure air blowing or vacuum cleaning, taking care to avoid dew points.
The substrate surface must be solid and all weak components and voids must be completely removed.

Mixing sequence

Before application, components A and B must be thoroughly mixed in the correct ratio. Use a low-speed mixer (maximum 300 rpm) or other suitable mixing equipment.
Mix for 2-5 minutes until the desired consistency and color are achieved.
Avoid creating air bubbles when mixing for too long. Then, pour the entire mixture into a clean container and mix again for about 1 minute at low speed to remove as much air as possible.
Only mix enough quantity to ensure optimal use during the product's construction period.

Construction

When used as a thin adhesive layer, apply the adhesive to the prepared surface using a trowel, spatula, notched trowel (or by hand wearing protective gloves).
When applying mortar for repairs, formwork is used.
When bonding metal to vertical surfaces, the material must be secured by applying even pressure and holding for a minimum of 12 hours, depending on the thickness of the adhesive layer (not exceeding 5 mm) and ambient temperature. After curing, check the adhesion by gently tapping with a hammer.

Toilet

Clean all tools and equipment immediately after use. Cured material can only be cleaned by mechanical means.
