Rubber Primer And Mortar Modifier


  • Ready to use.
  • Improve adhesion, flexibility and workability of cementitious plaster, render etc
  • Can be used as a primer for concrete, (1 part latex: 3 parts water)
  • Reduces shrinkage.
  • Improves the adhesion of repair materials to brick or concrete.
  • Increases the flexural and tensile strengths of mortars and concretes.
  • Imparts flexibility to site batched repair materials and floors.
  • Reduces the permeability and enhances durability.
  • Will not break down or re-emulsify.
  • Water based - mixing equipment and tools easily cleaned with water.
  • Economic, non-toxic and safe to use.


  • To give greater adhesion, workability and flexibility to all cementitious plaster, renders etc.
  • To penetrate and consolidate brick and concrete substrates.
  • To prime concrete and brick to increase bond strength of repair materials.
  • To waterproof site batched renders, mortars and concrete.
  • For site batched flooring materials, and repair materials for floors.
  • To prevent frost attack to brick and concrete.
  • For use as an adhesive with cement or cement mortar.
  • For use in chemically aggressive situations, e.g. food factories, dairies and fertiliser stores.
  • High strength or increased tensile strength applications.

Comparison with traditional systems:

CharacteristicsTraditional SystemsGeoplast Reusable Formwork
Hindrance-Modular system
ResistanceLimitedUp to 60 kN/m2
Concrete adherenceRequires dismantling agentsBeing made of plastics, GEOTUB PANEL does not stick to concrete
Protection10%The best protection for the columns until the end of the operations
PlumbingRequires long operations and it is often inaccurateQuick and accurate thanks to the external structure that allows easy shoring and plumbing
Dismantling agentsRequiredNot required. Everitt Site Supplies recommend 'Kleen Kote' protection and release formula to maintain your forms in top condition.
