Description

M-PRIME 104 - Damp Tolerant Concrete Primer

M-PRIME 104 – DAMP TOLERANT CONCRETE PRIMER Is a solvent-free clear epoxy primer suitable for the application to concrete surfaces with a moisture content up to 25%.

MPR 104 – penetrates deep in to the concrete and has excellent bond strength. The primer is applied as a single coat in most instances, but very porous concrete may require a second coat.

Typically, the product is used to consolidate concrete before the application of other coating materials usually epoxy, polyurethane or acrylic floor coatings.

But is also used as a bonding agent for epoxy concrete repair mortars or as a clear sealer for worn concrete to suppress any dust.

Typical Uses

  • Concrete Floors
  • Concrete Tanks & Reservoirs
  • Chemical & Fuel Bunds
  • Concrete Sumps Channel & Drains

Application Guide

  • Remove any surface contamination and lightly abrasive blast or scarify using mechanical hand tools taking care not to expose the aggregate.
  • Allow new concrete to cure for a minimum 21 days and remove any surface laitance before coating.

Prior to mixing please ensure the following:

  • Ensure the moisture content of the concrete is below 25%.
  • Suitable for applications where the surface temperature is 5°C or above
  • Mix the base component with the activator component in full units as supplied, ideally use slow speed paddle mixer.

  • When mixing both materials, it is essential to have a uniform streak free fluid.

  • Once mixed, the material should be used within 30-40 minutes at 20°C.

  • Apply the mixed material directly to the prepared surface using a brush, roller or standard airless spray.
  • Normally a single coat is enough but for very porous surface an additional coat may be required.
