Sika Bond LA

High‑performance latex admixture designed to enhance cementitious mortars used in concrete repair, screeds and protective floor toppings.​

Greatly improves bond strength between new mortar and existing concrete or masonry substrates, reducing debonding and surface failure over time.​

Increases flexibility and reduces shrinkage, helping to control hairline cracks and extend the service life of repair and rendering systems.​

Provides excellent resistance to abrasion and wear, making modified mortars suitable for high‑traffic floors and industrial areas.​

Delivers very good water resistance and waterproofing performance, supporting durable repairs in wet or moisture‑exposed environments.​

Enhances chemical resistance of cement-based mortars, which is beneficial in light industrial and service areas exposed to chemicals.​

Non‑toxic according to standard health and safety rules, when used as recommended and with normal site safety practices.​

Stable in highly alkaline concrete environments and does not break down as an emulsion, ensuring long‑term compatibility with cementitious substrates.

As a cementitious repair mortar admixture for structural and non‑structural concrete repairs that demand high bond strength and durability.​

For screeds and floor toppings that require improved abrasion resistance, impact resistance and reduced dusting in residential, commercial and industrial projects.​

In masonry mortars for stone and brickwork to improve adhesion, cohesion and overall performance of block and brick laying.​

For roughcast, key coats and rendering (plastering) on concrete or masonry, helping prevent delamination and hollow areas in internal and external finishes.​

As an admixture in tile and ceramic adhesive mortars to increase bond strength and durability in wet areas such as bathrooms, kitchens and balconies.​

As a bonding slurry between old and new concrete, ensuring monolithic behaviour and reducing the risk of cold joints in repair and extension works.
