Repair mortars are often used to fill these holes and gaps to ensure the subsequent underlayment can be applied level without uneven patches, rises or slumps in the surface – making them an essential product for the professional flooring contractor.

Bostik’s Rapid Repair Mortar is an ultra-fast curing cementitious compound with high polymer content. The sag resistant formula can be applied to any thickness to fill holes, gaps and cracks in floors. As it can be applied to any thickness, it’s also suitable for use in vertical applications, such as the levelling of steps and pedestals.
