      How to Use

      CERESIT CR 42 SUBSTRATE PREPARATION

      CERESIT CR 42 adheres to rough and porous substrate surface. Existing coatings, damaged render, fragments of walls and traces of salt efflorescence should be removed. Pre-wet the surface of the masonry or concrete prior application. On a matt-damp surface, make wart like scratch coat of CR 60 up to 5 mm thick, covering 50 % of surface of the substrate. CR 42 mortar should be applied approx. 24 hours after the rough cast was applied.

      APPLICATION OF CERESIT CR 42

      Pour the content of the package into the measured amount of 7,0 l of water and mix manually using a low- speed drill until a homogenous mass without lamps is obtained. The ready mortar should be used within 20 minutes. After the mortar has set, the main renovation layer of the profile must be done. Apply layers in maximum 20 mm thickness for each. The mortar should be applied manually and rework. After initial setting, it should be lightly rubbed, but not felted.

      IMPORTANT TO NOTE WHEN USING CERESIT CR 42

      Work should be carried out in dry conditions, at the air and substrate temperature from +5°C up to +25°C. All data refer to temperature +20°C and 65% relative air moisture content. In other conditions, faster or slower hardening of the material must be taken into consideration. Use correct amount of water to ensure best product performance. Do not mix with other materials. Protect skin and eyes.
