Rockbond 2.26 Shield HP is a high-performance cementitious coating system based on recycled glass, that has a high chemical resistance, a high wear resistance, and bonds to almost all substrates. Shield HP is ideal for use in water & wastewater treatment plants, dairy sheds, and other areas where high chemical resistance is vital. Shield can be used on most stable substrates including concrete, brick, block work, and steel.

This product is available in 10lt and 20lt pails and has a shelf life of 3 months when stored in cool, dry conditions.

How to use:

Apply with a roller, or a spray unit suitable for cementitious based products, to a thickness of 2-5mm. 2 coats maybe required to achieve this. If a second coat is required allow 3-4hrs between coats for the product to set – it should be firm to touch before recoating. Temperature and air movement can affect the set time, so allowances will need to be made for this. Each application of Shield HP will take approx 30 mins to become tacky at an ambient temperature of 16°C .Do not apply under 7°C ambient temperature as this could affect the cement setting. Shield HP may also be brush applied for smaller repair areas. Allow 3-4 hours curing, or until the product is dry to the touch before putting into service.
