Bostik Techflow Grout GP Grey 20kg Bag
High performance, non-shrink (Class C), dual expansion cementitious grout, with an application thickness of 10mm-140mm.
- Dual expansion compensates for shrinkage in the plastic and hardened state
- Ready to use, pre-mixed, and requires only the addition of water
- Can be pumped, trowelled, rammed or flowed to areas where normal grouting methods do not suffice
- Can be mixed for stiff, plastic, flowable or fluid application
- No metallic iron content to cause staining
- Lower water/cement ratio reduces drying shrinkage, increases durability and reduces permeability.
