Product Description

DESCRIPTION

EVERBUILD 503 Premium SBR Bond is a latex based, water resistant bonding agent and admixture for use in areas subject to humidity, dampness and water contact. Improves water resistance of cement mixtures by forming a reinforcing polymer that increases long term durability and flexibility of the mix on renderings and floor screeds. It contains anti-foam to control the density of cementitious mixes.

FEATURES AND BENEFITS

  •  Greatly improved adhesion to a wide range of substrates including dense concrete, steel, tiles etc.
  •  Mixes may be applied in much thinner sections
  •  Excellent resistance to water and water vapour
  •  A high level of resistance to salt permeation
  •  Much improved toughness and flexibility
  •  Reduced surface dusting of concrete
  •  Greatly improved resistance to many chemicals
  •  Reduced water: cement ratio for equivalent workability
  •  Improved frost resistance
  •  SBR Bond is also freeze thaw stable

USES

  • As an admixture for mortar/screeds/renders. 
  • As a bonding agent for screeds/renders. 
  • As a primer/sealer in tiling applications.
  • To increase flexibility for cementicious based tile adhesive when tiling on wooden/asphalt floors. 
  • In addition, SBR Bond has the advantage over PVA bonding aids in that it is not adversely affected in wet conditions and is therefore recommended for exterior use.

APPLICATION INFORMATION

  • Yield - As a rough guide, 1.2 litres of EVERBUILD® 503 Premium SBR Bond will cover 1m² of 12mm thickness using the below mixes.

SUBSTRATE PREPARATION

All surfaces must be clean, dry and free from dust, grease and other contaminants. The background must be capable of withstanding all stresses which will be put onto it and contain the appropriate joints. If it is to receive a topping the background should have a compressive strength greater than 30N/mm² and/or a tensile strength greater than 1N/mm². Floors should be mechanically prepared, eg scabbled or shot blasted, to give an aggregate exposed surface. Dust should be removed by vacuum, not compressed air. All contaminants such as oil, grease, or any surface laitence must be removed to ensure adequate development of bond when the topping is applied. A water drop test is the simplest method to determine whether water repellent contamination is present.

LIMITATIONS

  • In common with other SBR products, SBR BOND is not suitable for coloured exterior decorative renders which will not be subsequently overpainted. Its poor UV resistance may cause discolouration
