LATEX K5
Tackifying additive and non-shrink cementitious mortar
Water-based acrylic latex for cementitious compounds and plasters.
Type: Other Products
Descritpion
One-component waterborne acrylic resin, to be used as a modifier for cement-based mortars. Confers:
- excellent adhesion to the support
- increased flexural and impact resistance
- resistance to cracking
- greater impermeability without varying the diffusion of steam
- resistance in industrial environments
Use
- Plastic plasters.
- Cement levels.
- Castable mortars for floors.
- Promoter of adhesion.
Support
The substrate must have a minimum compressive strength of 25 N/mm2 and a tensile strength of 1,5 N/mm2.
Preparation of the support
Concrete bottoms must be solid, leveled, absorbent, not polluted by oils, dust or other substances.
Check the most convenient type of mechanical preparation. Remove damaged and detachment parts.
Any outcropping irons must be brushed and insulated with a special anti-corrosion primer.
Oily surfaces must be grinder by removing about 1 cm surface and treated with FLUIDEPOX, cross-linked with 40% epoxy quick hardener. Before laying the mortar, moisten the substrate abundantly. Then proceed with the coating, taking care to eliminate any stagnant water.
Application
Coatings with hydraulic binders
When preparing the mortar, instead of wetting with water only, use a 1 to 1 mixture of LATEX K5 in water. The coating based on inorganic binder will have greater flexural strength and lower water absorption.
As a promoter of membership
Dilute 1 to 1 with water and then apply immediately before casting or coating with mortar, for a consumption of 1 kg/m2 of diluted product. Pay attention that there is no drying of the product, in case reapply the same.
