5Kg – £65.00

ALLCOAT Oil Tolerant Primer is a two-component epoxy resin membrane that is tolerant of residual oil contamination in concrete floors. It is essential that all surface and gross contamination is removed by cleaning with ALLCOAT Degreaser.


  • Enables resin finishes etc. to be applied onto concrete that has previously been contaminated with engineering oils.
  • Easily applied by brush, roller or squeegee
  • Can be applied onto substrates with hygrometer readings up to 85% RH.
  • Completely solvent free and low odour.

Typical Uses
ALLCOAT Oil Tolerant primer can be used on concrete floors and fine concrete screeds, of not less than 50mm thick, in the case of unbonded screeds. The surface must be of sufficient quality, continuity and mechanical strength to ensure an even coating.

ALLCOAT Oil Tolerant primer is designed to improve the adhesion of coatings and screed systems to substrates that have previously been contaminated with oils, and have been thoroughly cleaned but may still retain some residual contamination.

ALLCOAT Oil Tolerant Primer will not bond to grossly contaminated surfaces and surface cleaning and preparation is an essential part of this process.

The product may also be applied to polymers, screeds and certain types of smoothing underlayments, provided these are well bonded. Such underlayments must be stable to the effects of water. If not the concrete floor must contain an integral damp-proof membrane to prevent further ingress of water from the ground.

Where laid onto a concrete surface where there is no damp proof membrane or where damage may have rendered the damp proof membrane ineffective due consideration must be given to the possible presence of hydrostatic pressure, and the consequences of creating a barrier layer resulting in the pressure /water flow being directed elsewhere.

ALLCOAT Oil Tolerant Primer is used in conjunction with ALLCOAT Degreaser. The surface should be mechanically prepared to remove as much as possible of the contaminated surface. Apply ALLCOAT Degreaser in accordance with the Data sheet, and allow to work for not less than 20 min. Agitate with a scruber and then wash off from the surface Several cleaning cycles may be required to achieve the necessary level of cleanliness. Rinse the surface thoroughly with clean water to remove any residues and allow surface to dry.

Inspect the surface to ensure that there is sufficient surface key and that there is no free oil contamination remaining (or that oily material has not risen from the underlying concrete).

Concrete surfaces must be prepared by scarifying, vacuum shot-blasting, planing or other suitable method. All traces of concrete hardeners or other contaminants must be removed. The surface must be thoroughly vacuumed to remove concrete dust and then protected against further contamination by suitable means. Surfaces must be free from liquid water and atmosphere must not be condensing.

Mix the contents of the hardener component with the base, using a slow speed power stirrer.
Apply the mixed material with a short to medium pile lambs wool roller. If additional coats of primer are required, these should be applied 24 to 48 hours apart. Further applications of the topcoat, screed, self smoothing epoxy or other floor covering may then be made.

Do not allow ALLCOAT Oil Tolerant Primer to set on tools. Clean with ALLCOAT Universal Cleaning Solvent.
