Cementitious Fibre Reinforced Mortar for the Sika Carbodur Grid 'M' (Masonry) System Sika MonoTop-3260 Grid is a one-part, cementitious fibre reinforced surface / finishing mortar. It is designed to be used in combination with the Sika CarboDur-300 Grid as part of the Sika CarboDur Grid System, which provides an efficient solution to consolidate and strengthen masonry. - Good adhesion to brick, stone and cohesive porous substrates (excluding plaster, gypsum, etc.).
- Sulphate and sea water resistant.
- Applied up to 40 mm thick in one layer on vertical and horizontal applications.
- Non-sag overhead at maximum thickness.
- Good workability.
- Hand and machine application (wet spray technique).
- Ready to mix with water.

Usage Sika MonoTop-3260 Grid may only be used by experienced and trained professionals. A Component of the Sika CarboDur Grid System designed to: - Reinforce masonry in civil engineering structures (e.g. aqueducts, sewage works, water tanks, etc.) or residential buildings.
- Retain masonry structures in the case of cyclic load and postpone the risk of collapse in case of earthquakes.
- Distribute stresses generated by movement of the structure to avoid cracks and detachment of the mortar.
- Improve the connection between masonry panels and reinforced concrete frames.
- Patch repair, repair bed joints on brick, stone masonry, block masonry and masonry curtain walls.
Advantages - Good adhesion to brick, stone and cohesive porous substrates (excluding plaster, gypsum, etc.).
- Sulphate and sea water resistant.
- Applied up to 40 mm thick in one layer on vertical and horizontal applications.
- Non-sag overhead at maximum thickness.
- Good workability.
- Hand and machine application (wet spray technique).
- Ready to mix with water.
