Commercial Buildings, Apartment Buildings, Office Buildings, Government Offices, Domestic applications, including concrete walls and columns, beams, and block walls, fibre cement sheeting and other areas where a strong Elastomeric Coating is to be specified.


Extremely flexible, waterproof and abrasive resistant with a low dirt retention factor.  It is recommended that it be glazed for extended durability.  Glaze coats available in varying degrees of gloss.


Available in Low Sheen or Gloss Finish.  Dries with a low profile texture, depending on method of application - roller or spray.  Hi Build is often applied over gun textured Shieldpatch on concrete, block walls, or over the Special Finishes' Strongwall Insulated wall Cladding System.


White can be tinted to many of the BS 5252 range.  On some surfaces only light to medium colours are recommend.  Refer to Special Finishes, or your applicator when specifying.


Most surfaces require a sealer, and reference should be made to the data sheet covering sealers prior to specifying Hi Build Acrylic.  In many cases such as concrete blocks, Hi Build Acrylic can be applied as a 2 or 3 coat system directly, but better results particularly against water ingress will be made if Shieldtex Fibre-Filled Concrete Block Sealer is used first.
