  • Elimination of dead zones on flat roofs

  • Wide horizontal movement joints

  • Seams in water tanks and pools

  • Runway seams


  • Versatile and easy to use

  • Does not shrink

  • Elasticity> 500%

  • Frost resistant

  • Repairable

Application steps:


Seams must be cleaned and dried prior to application. The surface must be free from traces of grease, oil, paraffin, silicone and other substances. If the bottom of the joint is open, a polyethylene foam sealing cord should be used, leaving a fill depth equal to half the joint width.


The primer is selected based on the type and condition of the applied surface. For absorbent surfaces with a residual moisture content of not more than 5% and metal substrates, it is recommended to use REDINGTON WET 5% primer, for surfaces with a residual moisture of 5% - 18% , use REDINGTON WET 18% primer, for PVC - based substrates, use REDINGTON PVC primer, for non - absorbent surfaces such as ceramic tiles and marble use REDINGTON GLASS primer.


Stir components A and B with a low - speed mixer (150 - 200 rpm) for 2 - 3 minutes until smooth. Next, fill the seam or stagnant area on the roof with sealant. After applying the sealant, the surface must be smoothed. The ready - made mixture should be used within 20 - 30 minutes at an average temperature of + 20 ° C. The open time can vary depending on the air temperature: decrease with increasing temperature and increase with decreasing temperature.
