Substrate

Apply on cement-based substrates, such as renders, screeds, and concrete.

On reinforced concrete surfaces, an adhesion promoter should be applied.

Concrete or masonry walls and floors must be at least 30 days old, while plaster and screeded mortar must be at least 14 days old.

If the bonding is done on highly absorbent vertical surfaces, they should be pre-moistened before applying the cement adhesive.

It should be applied on flat and regular walls, with a surface deviation of no more than 2 mm per linear meter, proceeding with any necessary surface corrections.

Application Method

The mixture should preferably be made mechanically, using a low-speed mechanical stirrer.

Mix the contents of the 25 kg bag with approximately 3.75 liters of clean water until a homogeneous mixture is obtained, free of lumps. Once mixed, the adhesive should be used immediately.

Spread the adhesive evenly with a notched trowel (8 to 10 mm) and then place the piece to be bonded, pressing it with vibrating movements. Allow for joints of at least 2 mm between the pieces, which should be filled with mortar and joint compound capable of absorbing the dimensional variations of the pieces. Joint filler can be applied between 24 to 48 hours after bonding.

Whenever higher efficiency or bonding of larger pieces is required, a double bonding method should be used.

Once applied, the adhesive has a 20-minute adjustment time.

The floor can be used by the construction personnel with caution after 4 hours.

Safety

It is recommended to use a dust mask to protect the respirable crystalline silica, goggles and gloves when handling the product. If there is contact with eyes, rinse thoroughly with clean water. Do not ingest.
