Product Description

Centrecoat Thermoplastic Primer is a single pack, solvent borne, acrylic resin based, thermoplastic primer for concrete and block paving.

Best Uses

When applied onto old concrete or blocks, Centrecoat Thermoplastic Primer penetrates into the pore structure thereby sealing and dust proofing the surface, to aid the adhesion of thermoplastic line markings and logos.

  • Easily applied by brush, roller or spray
  • Single pack – ready to use
  • Good chemical and abrasion resistance
  • Seals and dust-proofs the surface
  • Resistant to ultra violet radiation
  • Provides easily cleanable floor surface
  • Internal and external use

When applied to freshly placed concrete, Centrecoat Thermoplastic Primer functions as a curing membrane, reducing any tendency towards drying shrinkage cracks. At the same time, the surface becomes sealed against the ingress of oils and many aqueous chemicals, and a harder wearing floor is produced.

This product can also be used as a curing/sealing treatment to new concrete, and as a sealing/dust-proofing treatment to old concrete and blocks to provide a sealed and dust-proof surface with resistance to the ingress of oil, petrol and chemical spillages.


On old concrete, apply a coat of Centrecoat Thermoplastic Primer by brush, roller, squeegee or spray at a nominal rate of 8-9m²/litre.

On new concrete, apply Centrecoat Thermoplastic Primer by spray at 5m²/litre. Apply evenly and avoid the formation of puddles of excess material on the surface. On block paving, ensure material is applied to fully seal the surface. Coverage is dependent on the porosity of the block.
