Concrete Sealer

Concrete Sealer   Description A non-yellowing clear polymer emulsion. Purpose Provides a tough, durable, flexible, clear coating on vertical surfaces of concrete, cement plaster and masonry. Concrete Sealer combines aesthetic appeal with protective performance. The main properties are UV resistance, non-yellowing, resists becoming brittle, waterfast, alkali resistant, water vapour permeable and carbon dioxide tight. It is therefore invaluable for protecting concrete reinforcing against corrosion caused by carbonation. It has good binding properties on friable surfaces and is recoatable. Applications Recommended for the sealing of concrete against staining, mottling and general discolouration. Useful for protecting architectural and exposed aggregate concrete, split concrete masonry and brick walls. Types Available in gloss and semi-gloss. Colours Clear only. Specifying “Apply in 2 coats Cemcrete Concrete Sealer using a paint roller or paintbrush. Surface to be dry and absolutely clean. Minimum of 1 hour between coats. All in accordance with the manufacturer’s instructions.” Note Not for use on slate or new quarry tiles. Not for use in watercontaining structures. Site Work Suitable Surfaces Architectural concrete, split concrete bricks, exposed aggregate concrete, brushed terrazzo, brick walling. All surfaces should be hard, dry and free from anything which could prevent penetration of the sealer. It is essential that curing membranes and shutter release agent be completely removed. Surface Preparation Surfaces should be clean, hard and dry at the time of application. Masking For best results all windows, doors and adjacent surfaces should be masked using masking tape and brown paper. All masking material must be removed at the end of the day. Mixing Use straight from the can after stirring. Application Apply liberally straight from the can using a large paintbrush or sheepskin roller. Two thin coats applied with an hour interval are better than one. Specimen finish A trial area should be treated on-site for the architect’s approval.
