Gibco MRF Additive
97100560
Gibco MRF is a concentrated admixture, formulated as a replacement for lime in masonry and plaster mortars. At standard dosage, this 8 ounce tub will treat 22 gallons (100 litres) of water.
Gibco MRF replaces lime and other additives in masonry and plaster mortars. For cements or mixes with lime already present, it should be used at reduced dosage.
Gibco MRF has three notable attributes:
- as a plasticiser - improving the workability of mortars
- greater air entraining - improves workability and resistance to freeze/thaw cycles
- water reducer - increases both compressive and bond strengths
It will also minimise shrinkage and efflorescence and enhance weather resistance.
