Fosroc Dekguard Elastic is a high performance crack-bridging elastomeric acrylic protective and decorative coating for concrete and masonry conforming to the requirements of BS EN1504-2.

Best Uses

Fosroc Dekguard Elastic is formulated to protect atmospherically exposed reinforced concrete structures from attack by acid gases, chloride ions, oxygen and water, especially where there is a danger of subsequent cracks appearing within the substrate. The product is also suitable to protect other cementitious substrates and masonry.

Dekguard Elastic is suitable for use on all types of structures, including those in coastal environments. It is equally suitable for new and existing structures. Dekguard Elastic is a component of Fosroc’s Renderoc system of concrete reinstatement and is suitable for repair principles 1.3, 2.2, 8.2 as defined in BS EN1504-2.

  • Can accommodate substrate cyclic movement of up to 1mm
  • True elastomeric coating with excellent elongation and recovery properties which are maintained at sub-zero temperatures
  • Excellent barrier to carbon dioxide, chloride ions, oxygen and water
  • UV-resistant with high resistance to the effects of long-term weathering
  • Water-based
  • Wide range of decorative colours available on request

The Dekguard Elastic system comprises a single component penetrating primer and a single component elastomeric pigmented coating, both ready for immediate site use. Dekguard Elastic is an elastomeric, water based protective coating based on a special acrylic polymer. It provides excellent elongation and recovery, low dirt pick-up, resistance to aggressive elements, UV light and rain. It is available in a wide range of colours.


Apply the priming coat Dekguard CP, in one coat until the recommended application rate of 0.25 litre per square metre has been achieved. This is best accomplished by using portable spray equipment of the knapsack-type. A uniform surface appearance (sheen) should be achieved. If any matt porous patches remain, a further application of primer should be made.Allow the primer to dry for a minimum of 6 hours (at 20°C), longer at lower temperatures. Under no circumstances should the primer be overcoated with Dekguard Elastic until the surface is properly dry.

When applying Dekguard Elastic over existing coatings, Dekguard CP is not required, refer to the Overcoating section for priming instructions on the product data sheet. When applying Dekguard Elastic directly over surfaces treated with Protectosil® CIT, the use of Dekguard CP primer is not required.

Dekguard Elastic may be applied by the use of suitable brushes, rollers or spray equipment. All primed substrates should be treated with two coats of Dekguard Elastic. It is important that no gaps or ‘raw edges’ appear in the finished coating. Special care should be taken to provide an unbroken coating at external corners and similar exposed protrusions. Apply the first coat to all areas until a uniform coating with a wet film thickness not less than 400 microns is achieved. Allow to dry until firm to the touch. Typically, this will be after about 16 hours in dry weather at 20°C. Apply the second coat of Dekguard Elastic as above.
