MMA Concrete Joint Filler

CPR 714 – MMA Concrete Joint Filler is a light grey, two pack, pourable, flexibilised Methacrylate sealant. The consistency of the mixed sealant allows direct pouring of the sealant into horizontal joints. The Joint Filler is hard and tough enough to protect arris edges from heavy wheel loading, but possesses sufficient flexibility to accommodate a degree of movement (10% of the joint width).

CPR 714 – MMA Concrete Joint Filler is particularly suitable for filling saw cut joints in long strip floor construction.


The product is used to seal floor joints in food factories and warehouses where heavy vehicular trafficking occurs.

Typical Properties

  • Excellent adhesion to concrete
  • Tough and resilient
  • Suitable for wide joints
  • Highly resistant to water
  • Easy to apply
  • Fast curing, even at very low temperatures
  • Hygienic and easily cleaned

Direction For Use

Surface Preparations

  • New concrete floors shall be a minimum of 21 days old. Joint surfaces shall be sound, clean and free from laitance, dust and other contaminants.
  • Joint arrises are best prepared by grinding or power wire brushing, ensuring that all spoil and residual dust is removed by blowing with dry, oil free, compressed air.
  • For best results, prime the joint edges using CPR 406 – MMA Concrete Primer and allow to cure for a minimum of 45 minutes.
  • De-bonding tape should be used in the base of the joints otherwise a polyethylene foam backing strip should be inserted to the appropriate depth.


  • Is supplied as a two pack material consisting of the BASE component, and the CATALYST component.
  • Pour the entire contents of the CATALYST container into that of the BASE component, and thoroughly mix until a uniform consistency has been achieved.

Joint Design

  • When using CPR 714 – MMA Concrete Joint Filler the joints shall be designed to ensure that concrete movement due to shrinkage and temperature fluctuations does not exceed 10% of the joint width.
  • For joints up to 12mm wide, the depth of sealant should be equal to the width.
  • For joints over 12mm wide the depth of the sealant should not exceed 20mm. Joints over 25mm wide are permissible.


  • The mixed material may be poured directly into the prepared joints to level.
  • Alternatively, the Concrete Joint Filler may be poured into empty cartridge tubes and gunned into the joints using a sealant gun.
  • It may be necessary to top up to level after a few minutes when the sealant has settled into irregularities.


  • CPR 714 – MMA Concrete Joint Filler will have cured sufficiently after 1 hours cure @ 20°C to allow full trafficking.
  • Full chemical resistance will be achieved following 24 hours cure @20°C.
  • At lower temperatures cure times will be increased.
  • Pre-accelerated grades of the material can be provided for sub-zero application.

Equipment Cleaning


  • Do not apply to wet or uncured concrete.
  • CPR 714 – MMA Concrete Joint Filler will taint food during application, so that all foodstuffs in the immediate vicinity must be removed or properly covered.


  • A 1 litre pack of joint filler is sufficient for 10 linear metres with a 10mm x 10mm joint.
