Masonry Repair with Twistfix Crack Sealer

For many reasons, cracks may appear in brick, stone, and block walls. After identifying and rectifying the cause, the cracks should be immediately repaired, and one of the quickest and easiest ways to carry out this vital work is to use Twistfix Crack Sealer

Twistfix Crack Sealer is a thixotropic epoxy adhesive supplied in two parts. It is suitable for repairing even the narrowest of cracks in masonry (down to a tiny 0.2mm). Ideal for all kinds of masonry, the specialist formula complements structural crack stitching repairs, rapidly delivering a reliable, fully waterproof seal to help prevent the severe damage caused by repetitiv freeze/thaw cycles.

How to Use Twistfix Crack Sealer 

  • The first step is to remove any friable or loose dust. This should be done by using a vacuum or air blower. Make sure that all material is removed before commencing.
  • The formula comes in two parts: a base and a hardener. Add the contents of each container to an appropriate vessel and mix thoroughly together with a mixing knife.
  • Place the included follower plate flat onto the surface of the resulting mixture, ensuring that its outer and central lips point upwards. 
  • Take the included empty cartridge, placing its back end centrally and vertically over the follower plate's hole. Press the cartridge down continually and firmly until the plate reaches the base of the mixing tub.
  • The cartridge will now be filled; remove it carefully and invert.
  • After assembling the included nozzle adaptor and nozzle onto the cartridge, insert the rear plunger. Place the assembled unit into a skeleton gun.
  • You can now proceed to inject the sealing formula directly into the bases of all cracks, working outwards and ensuring that each crack is completely filled. Any excess should be immediately removed with a lint free cloth that has been dampened. 
  • If colour match needs to be improved, you can apply brick dust to the substrate when the adhesive has reached a tacky stage. Never mix brick dust into the sealer as this may cause difficulties when dispensing. 

Twistfix Crack Sealer is available at the most competitive price in two different colour options: Brick Red or Concrete Grey. Each 300ml pack contains enough formula to repair the equivalent of a crack measuring five metres in length and two millimetres in width, with a 30mm deep injection.
