Description

Essential for preparing bare concrete ready for painting Acid based, neutralises when it’s done the job Colour change indicator shows when it’s finished Etches and removes dirt and light oil Prevents new paint from flaking and peeling Watco Etch & Clean is the ideal way to prepare concrete and brickwork surfaces for painting. It will remove surface laitance and will also neutralise excess alkalinity in new concrete (concrete must be at least 4 weeks old before use). Features Ensures excellent bonding of coatings and reduces alkalinity of new concrete Contains detergent for cleaning action Removes laitance (a weak dusty layer) on new concrete and will provide a key for surface coatings on very smooth concrete Gel formula to provide more even etching over surface Colour change system to indicate neutralisation Application Etch & Clean Application Apply Etch & Clean to a maximum area of 20m² per 5 litres in conjunction with harsh scrubbing by a soft broom or machine and leave for 15 minutes until all frothing stops and the formulation has changed from pink to white/clear. Once the colour change has occurred the surface alkalinity has been fully neutralised. Flush the area with generous amounts of water to remove all traces of Etch & Clean and allow the area to dry thoroughly before painting. Brush and vacuum the surface to remove loosened particles of laitance. If a fine powdery film can still be easily removed from the surface, more etching with Watco Etch & Clean will be necessary.
