This high-movement joint repair system consists of a low-viscosity polyurethane primer, which ensures deep penetration and strong adhesion on both porous and non-porous substrates. This is followed by a moisture-curing, non-sag elastomeric polyurethane sealant that provides long-term elasticity and high mechanical resistance. The system is completed with a waterproofing, carbonation-resistant acrylic coating, applied at high film thickness to bridge cracks up to 100 microns and deliver durable protection against water ingress and harsh weather conditions.
