      How to Use

      Joint preparation

      The joint surface must be clean, dry and free from oil, loose particles, cement laitance and other contaminants which may affect the adhesion. A thorough wire brushing, grinding, sand blasting or solvent cleaning may be required to expose a clean and sound substrate. On painted surfaces all loosely adhering paint must be removed, if in doubt remove all previous decorations. Remove all round or sharp edges and corners which might perforate or cause damage to the backing rod. The compressible joint filler shall be cut back to expose a uniform joint depth.

      Installation

      Select a backer rod whose diameter is at least 20% larger but not greater than 33% of the joint width. This will ensure that the backer rod remains in compression and in place during sealant installation. The backing rod shall be inserted into the joint by using a blunt tool or roller and forced gently into the joint till the desired depth is achieved, whilst making no damages to the joints & edges.

      Storage

      Store in a cool, dry place and keep away from all sources of heat.
