Surface Preparation:

For best results, ensure surfaces are thoroughly cleaned, degreased and lightly abraded. 

Grind out fine cracks in a V-shape to around 0.5cm wide. 

If depth is less than 1/2 the width, apply a back filling. 

Prime any crack edges with Parafix, Pegafix or Vernac. 

Hard PVC should be primed with Primer 44HS

Metal and Glass to be primed with diluted Noxyde

On Porous surfaces, always use an appropriate primer. 


Apply by manual spray gun, spatula, palette knife, or glue spreader. 

Joints have to be smoothed with a finger or with a cloth soaked in Thinner, or in water and soap. 

The surface in contact with the air must be sufficiently large as the Elastofill will transform into a rubber like mass by the evaporation of water.

Apply at a minimum temperature of 5 Degrees C. 

Relative humidity 80%
