WB25 Epoxy


WB 25 Epoxy is a clear two-part water based epoxy.


WB 25 Epoxy can be used as a Primer / Binder & Sealer or Concrete Repair Mortar.


  • Can be applied to damp surfaces
  • Binds concrete surfaces
  • Seal surfaces from oil, grease and dirt.
  • May be overcoated


All surfaces to be treated must be structurally sound, clean and free from previous coatings, adhesives, dirt, grease, oil or other surface contaminants.  Very dry and highly porous surfaces should be sprayed with a fine mist of water prior to application of WB 25 Epoxy.


Mix the hardener component, then the resin component, then thoroughly mix 1:1 by volume, the required amount of the two components together in a separate, clean container.  Preferably use a power stirrer for mixing.  Only mix as much as may be used within the pot life of the product, avoid excessive aeration.


  • Do not apply if temperature is below 10’c or above 35’c.
  • Do not apply if rain is imminent.

Concrete Sealer (Interior)
Dilute mixed product by 50% i.e. 20 litre kit and 10 litres of water.  Apply with a long nap roller, 2 coats and approximately 8m2 per litre coverage. (Will vary depending on texture)
Concrete Repair Mortar
Mixture is to comprise of 1 part cement, 3 parts sand to 1 part by volume of WB 25 Epoxy.


WB 25 may be used as a bonding agent prior to the application of the repair mortar.


Wet weather and Ponding should be avoided when using WB 25 as a sealer.  WB 25 is not recommended for use in exposed sunlight.


Allow to cure for a minimum of 24 hours at 25°c/50% R.H before applying adhesives, mortars, or decorative coatings.  Allow longer for lower temperatures or higher humidity.


Wash all equipment in fresh water immediately after use.
