Description A clear acrylic polymer resin solution primarily for application to surfaces of freshly laid concrete where it has a double function, firstly to form a highly effective curing membrane that conforms to ASTM. C309 and secondly to act as an in-depth sealer for the hardened concrete rendering its surface dustproof and extremely hard wearing. Its secondary function and benefits are also applicable when the material is applied to existing concrete surfaces.
Benefits • Cures and seals in one operation saving time and labour. • Ideal for use in fast-track construction • Curing efficiency 75% in accordance with ASTM. C309 • Provides abrasion resistant hard wearing easy-clean surface • Effective anti-carbonation coating • Permits bond of most subsequent coatings intended for concrete
Usage instructions New concrete Apply by fan-jet sprayer to achieve a minimum coverage of 6 m2 per litre immediately after final finishing and when surface water is no longer evident. Existing concrete Apply by sprayer as above to surfaces that should be clean, sound and free of laitance oil, paint or any other contaminants. A dry surface is preferable as it permits easier penetration but a damp surface is acceptable providing there is no standing water.On very porous surfaces that will be evident by rapid absorption of the material, an additional coat will be required after the first has become touch-dry.On impermeable surfaces penetration will be improved by thinning the material with up to 20% white spirit. Apply a second coat if necessary, after the first has become touch-dry. Typical data Touch Dry Time: 2 to 4 hours dependent upon temperature and wind Hard Dry Time: 18 to 24 hours dependent upon temperature and wind Curing Efficiency: 75% @ 6m2 per litre Flash Point: 40°C
