SikaLatex® MY
Formally known as SikaLatex®. SikaLatex® MY is a modified styrene butadiene emulsion to be mixed with cement (neat) or cement / sand mortar for improved adhesion and water resistance properties.
- Increases adhesion, flexural and tensile strength
- Improves abrasion resistance (less dusting)
- Reduces water permeability
- Increases chemical resistance
- Non-toxic, non-corrosive and non-flammable
- Easy to use
- Does not re-emulsify even in high alkaline conditions
Usage
- For higher strength floor screeds with less ‘dusting’, improved flexibility and resistance to cracking
- For wear resistant floor toppings in water treatment works, sewage systems, etc. together with Sika®-1 System
- As an additive to repair mortars for patching and filling
- As a bonding agent for rendering, tile fixing and masonry jointing mortars, etc.
- As a bonding grout between old and new concrete, as well as in construction joints
Advantages
- Increases adhesion, flexural and tensile strength
- Improves abrasion resistance (less dusting)
- Reduces water permeability
- Increases chemical resistance
- Non-toxic, non-corrosive and non-flammable
- Easy to use
- Does not re-emulsify even in high alkaline conditions

MIXING
Mix sand and cement first, then add SikaLatex® MY solution as required (SikaLatex® MY solution is SikaLatex® MY diluted with water – see ‘Mortar Mix Design’). Mix either by hand or with a low speed drill for no more than 2 minutes.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened or cured material can only be mechanically removed.
