Getting started

Before use:

Working conditions

Do not use in temperatures ≤ +5°C.

Preliminary surface treatment

Surfaces must be dry, clean and free of dust and grease. Sand them if necessary.


Cartridge gun, spatula

During use:

Directions for use

  • Apply coating with a cartridge gun and spread out within 10 to 15 minutes using a spatula or similar tool. After 30 to 60 minutes a surface skin forms, which can be loaded with (light) rainfall after 2 hours. Completely waterproof after 24 hours and is fully cured after 48 hours, depending on the layer thickness which is applied and ambient circumstances.
  • Minimum layer thickness: 2 mm.
  • Usage: 1.5-2.5 L/m2.


Minimum layer thickness: 2 mm.

Points of attention

  • Do not apply at temperatures below +5°C. May be charged with (rain) water after 12 hours.
  • If a joint sealant is used in combination with Rubber Seal®, we strongly recommend to use a neutral silicone sealant, for example a Silicone Sealant Construction, to prevent discoloration of the sealant.

After use:

Storage conditions

  • Properly sealed packages should be stored in a dry, cool, frostproof location at temperatures between +5°C and +25°C.
  • Shelf life: At least 18 months in unopened package. Opened packaging reduces the shelf life.
