Essential Concrete Sealer is a professional, solvent-free product that seals and protects concrete surfaces. Providing great water repellency and stain resistance to external and internal concrete surfaces, while also assisting in the reduction of efflorescence, moss, and algae growth, and allowing the surface material to "breathe" and transfer moisture vapour. A technological, synthetic resin emulsion that lowers capillary water absorption on treated surfaces while not clogging the pores or capillaries. Dependant on the porosity of the surface, coverage should be 4 – 10m² per litre per coat. Check the surface after application to ensure the full effectiveness of repellent. Available in 5L and 25L. HOW TO APPLY: 1. Remove any loose debris from the work surface before beginning your work, and make sure you have adequate personal protection, such as gloves , proper protective eyewear , a face mask , and appropriate clothing. 2. Perform a tiny test application on-site in an unnoticeable spot prior to usage, following the directions below. This will indicate whether or not the product is appropriate for your surface. 3. The surface must be totally clean and dry before application. Low-pressure sprayers , rollers , natural fibre brushes, and sponges are all options for application. 4. To guarantee total coverage, apply two coats of Essential Concrete Sealer "wet on wet." DON'T DILUTE. After 45-60 minutes, the surface will be dry. If rain is forecasted or begins, stop treatment right away and cover the freshly saturated areas; the surface must be entirely dry for the first 6 hours following application. PLEASE NOTE: The use of Essential Concrete Sealer may produce a change in the appearance of some surfaces; always test the product in an unnoticed area before using it where appearance is critical. Masking tape should be used to protect surfaces that will not be sealed.
