Fosroc Nitobond Sbr

What Fosroc Nitobond SBR Is Fosroc Nitobond SBR is a styrene-butadiene rubber (SBR) polymer emulsion used as a bonding agent and additive for cementitious mixes (like mortars, screeds and plasters). It's a white liquid that you mix with cement-based materials to improve performance. Basically, it's not just a glue — it actually modifies the cement mixture to make it stronger and more resilient. �� Main Uses It's often used in construction and repair work with: ✔ Concrete repair mortars ✔ Floor toppings and screeds ✔ Waterproof renders and cementitious slurries ✔ Bonding new mortars to old concrete/surfaces ✔ Repairing cracks and damaged concrete ✔ Plaster and masonry work You can even use it to make polymer-modified floor screeds or a strong bonding slurry. �� Why It's Useful Here's what it actually does when added to cement mixes: �� Boosts adhesion — sticks new mortar/floor screeds firmly to old surfaces like concrete, masonry, stone, plaster. �� Improves strength — better tensile and flexural strength means fewer cracks and more durability. �� Enhances workability — makes mixes more cohesive and easier to apply. �� Water-resistant finish — reduces permeability so surfaces resist moisture and chemicals. �� Versatile — suitable for horizontal, vertical and overhead applications. �� Single-component liquid — straightforward to mix on site with cement. �� How It's Used You typically replace water in your mortar mix with Nitobond SBR to: Make bonding slurries or primers before applying repair mortar Produce polymer-modified mortar or screed with better performance Waterproof renders and reduce shrinkage in cement mixes The exact proportions vary by application — consult the product's technical data sheet (TDS) for precise mix ratios and instructions. �� Packaging & Types Nitobond SBR is usually available in liquid form in different pack sizes like 1 L, 5 L, 20 L and larger drums, depending on supplier and region. �� Quick Tip There's also a format often referred to as Nitobond SBR Latex, but this is essentially the same type of styrene-butadiene emulsion used as a bonding modifier in cementitious mixes — "latex" just highlights its polymer nature in some product listings.
