Visqueen Axiom CreteSeal is a low modulus structural concrete expansion joint sealant. The formulation contains both PU and silylated-PU technology resulting in a sealant which includes the best of both technologies and is easy to apply even at temperatures. It has been modified in order to give enhanced thixotropic properties.
CreteSeal cures by reaction with atmospheric humidity to produce a joint sealant with a 50% joint movement accommodation factor. Additionally, the CreteSeal has been modified in order to have extrusion profile identical to hybrid PU or MS technology. The extrusion rate and tooling of the sealant remain the same throughout a very wide range of temperature and humidity conditions.
The product is specially formulated for structural movement joints in concrete.
Joint surfaces must be clean, dry and free from frost. Remove all dirt, laitance, loose material and foreign matter. Remove all rust, scale and protective lacquers from metal surfaces.
Removal can be achieved by grinding, grit blasting or wire brushing. Slide the sealant into the applicator gun, cut off the very end of the sealant packaging and fit the gun with the nozzle that has been cut to deliver the right bead size.
Extrude the sealant into the joint ensuring that no air is trapped in the joint. Wide joints will require more than one pass of the application gun to make sure that sealant is in full contact with the sides and bottom of the joint.
Tooling is recommended immediately after the application of sealant.
