Clean-up
Wet product: Soap and water.
Dry product: Scraper and mineral spirits.
Storage
Between 15°C (60°F) and 30°C (85°F)
Surface Preparation
Materials, adhesive and room must be maintained at a temperature of 15°C (60°F) to 30°C (85°F). Surfaces should be clean and free from all contaminants. Stir thoroughly before use. Concrete: Concrete surfaces must be thoroughly cleaned. They must show no signs of curing agent that can interfere with adhesion. The surface should not be brittle, soft or fragile. All concrete surfaces must be completely free of efflorescence salts, moisture or hydrostatic pressure. After the cleaning, let the concrete dry for 24 hours. The concrete temperature should be above 5°C (40°F). Check for efflorescence salt. If necessary, treat the surface with a solution of 5 to 10% muriatic acid (hydrochloric) or other acidic solution provided for this purpose. Leave on for 20 minutes or according to the product instructions. Rinse several times with water and allow it to dry thoroughly (at least 24 hours).
Product Application
As an adhesive: Apply the product followed immediately with the mortar. As an additive for mortar: Use 925 mL of product for 4 kg of cement and 9 kg of clean dry sand. Mix half and half LIQUID NAILS LN-520 and water. Slowly add the premixed cement with the sand. Never add the liquid to the powders. If the mixture is too thick, add a small amount of water. Always apply on a damp surface or on a surface covered with LIQUID NAILS LN-520. Level the concrete within 30 minutes. Humidify the surface within the fist 24 hours. Note: On materials other than concrete, surfaces must be covered with LIQUID NAILS LN-520.
Working Time
As an additive, level concrete within 30 minutes.
As an adhesive, coat within 10 minutes.
Fully cures within 28 days.
