Powdered Additives

Performance additives are crucial components of dry-mix mortar, ensuring products consistently achieve their design specification.

Oscrete supplies a comprehensive range of powdered additives for the dry mortar sector, supporting specialist manufacturers across the UK and Ireland. Our expertise spans key product categories including levelling compounds, repair mortars and tiling products, with tailored solutions designed to meet the demands of modern construction environments.

Oscrete produces a wide range of powdered additives at our Bradford (UK) factory as well as distributing products from global brands such as Elotex and Newchem.

Our range

• Redispersible powder polymers, accelerators, retarders, superplasticisers, air entraining additives, shrinkage reducers/compensators, water repellants, defoamers, viscosity modifiers

How additives enhance the performance of dry-mix mortars

• Improved Adhesion: Redispersible Powder Polymers, and Cellulose Ethers create a strong bond between the mortar and the substrate, such as concrete or tile.
• Reduced Set Time: Powdered Accelerators speed up setting times, allowing faster working and a quicker return to service.
• Better Workability: Air entraining additives improve the fluidity and smoothness of the mortar whilst increasing resistance to freeze thaw action.
• Greater Water Retention: Cellulose Ether helps the mortar retain water, which is crucial for the proper curing of cement-based products.
• Enhanced Flow: Superplasticisers improve both the flow and retention of dry mix mortars making for easy placement of fluid systems.
• Increased Water Resistance: Hydrophobic additives reduce the water absorption of mortars, protecting substrates and increasing durability.
