Description

M-CRETE 300 – Acid Resistant Epoxy Novolac Concrete Screed

M-CHEM 300 – Acid Resistant Epoxy Screed is formulated using an highly acid resistant Epoxy Novolac Resin System.

M-CHEM 300 – Acid Resistant Epoxy Screed is solvent free and has been designed for various concrete repair applications and to protect concrete surfaces in high traffic areas where concentrated acids and industrial chemicals are present.

The product can be applied to new or old concrete and should be applied at a minimum thickness of 5mm with a maximum of upto 20mm.

Typical Uses

Application Guide

Existing Concrete

  • If the concrete surface is contaminated, pressure wash using clean water.
  • Once the concrete is dry, lightly abrasive blast or scarify taking care not to expose the aggregate.
  • Clean all dust and debris from the surface and take several moisture readings and prime with M-PRIME 100 – Low Viscosity Epoxy Concrete Primer or M-PRIME 104 – Damp Tolerant Concrete Primer dependant on moisture readings obtained.
  • Apply M-PRIME 100 or M-PRIME 104 at a target wet film of 150 microns, allow to cure before overcoating.
  • For very porous surfaces a second coat of primer may be required.

New Concrete

  • Allow new concrete to cure for a minimum of 21 days lightly abrasive blast or scarify to remove any surface laitance.
  • Clean all dust and debris from the surface and take several moisture readings and prime with M-PRIME 100 – Low Viscosity Epoxy Concrete Primer or M-PRIME 104 – Damp Tolerant Concrete Primer dependant on moisture readings obtained.
  • Apply M-PRIME 100 or M-PRIME 104 at a target wet film of 150 microns, allow to cure before overcoating.

For very porous surfaces a second coat of primer may be required.

Prior to mixing please ensure the following:

  • The base component is at a temperature between 15-25°C.
  • Do not apply the material when the ambient or substrate temperature is below 10°C or less than 3°C above dew point.

Contents

1 x 30kg Unit of M-CRETE 300 consists of:

  • 1 x 4ltr of M-CRETE 300 Screed Resin (grey or red) and Activator (amber).
  • 1 x 20ltr pail containing 24kg of aggregate

Mixing

  • Empty the contents of the M-CRETE 300 – Activator into the M-CRETE 300 – Base tin and mix using a low speed electric paddle mixer.
  • Ensure all the material is thoroughly mixed and streak free, pay attention to the sides and bottom of the tin. Once mixed, pour the resin into a forced action mixer.
  • Add approximately half of the supplied aggregate to the resins in the forced action mixer and mix for 2/3mins.
  • Once the resins and aggregate are full wetted, gradually add the remainder of the aggregate to the resins.

Warning

  • When the product is being applied to concrete surfaces lower than 12°C, add 50% of the aggregate and check the consistency of the mix. Colder temperatures will thicken the resin and therefore less aggregate is required to create a trowelable screed.
  • Once the resins and aggregate are full wetted, gradually add the remainder of the aggregate until the required consistency is achieved. Do not worry if you have some aggregate left.

Use all mixed material within 25 minutes at 20°C.

  • To apply M-CRETE 300 chemical Resistant Epoxy Screed Empty the contents from mixer onto the repair area.
  • Spread the screed with a trowel or rubber squeegee and then smooth off to the correct level.
  • Once the repair area has been filled with material spray clean water onto the face of the trowel and skim the surface of the repair.
