Sika ® -4a is a ready to use, liquid waterproofing compound. When mixed with cement it sets rapidly to seal areas of severe water infiltration. The product is suitable for use in tropical and hot climatic conditions.
Sika ® -4a is used for preliminary waterproofing work on wet surfaces, prior to the application of subsequent cementitious renders. It can also be used for fixing bolts and anchors in rock or concrete.
Sika ® -4a is part of a range of internationally used normal and quick setting waterproof admixtures.
SBR based multipurpose ploymer for repair & waterproofing Sika® Latex Power is a synthetic rubber emulsion which when added to cement slurry/ cement mortar/ concrete/ grout provides good adhesion and water resistance. It comes in the form of a milky liquid. It is fully soluble in water and is to be added directly to the gauging water of mortar/ concrete/ cementitious grout.
For waterproofing of roof slabs, sunken slabs, basements, water tanks, sunshades, etc. in combination with cement
As a bonding agent for uses in repair and plastering
For making polymer mortar for repairs mortars, etc.
Treatment for leaching and saltpetre action
Multipurpose mortar admixture for injection grouts
Advantages and Characteristics:
Improves elasticity, flexibility, tensile strength of cement and reduces cracking
Makes the mortar waterproof and reduces susceptibility to acids and gases, saltpetre action, etc.
Mortar with Sika® Latex Power shows extremely good bonding to bases like concrete, stone, brick, etc.
Reduces viscosity of cement injection grout and improves bond of cured injected materials with substrates
Sika® Latex Power can be diluted with water (1 : 4 - 6) depending on the type of application
Screed required with Sikacim® / Sika® Plastocrete Super to protect waterproofing layer
Standard coating system can be further reinforced by placing Sika® Fab 1 fabric layer in between 1st and the 2nd coat
Adhesion to most substrates(concrete,stone,brick,ferrous metals,glass,ceramic tiles)
Makes easy to use,non-toxic & plastic mortar for repair
Inhibits cracking,improves surface hardening,limits wear and dust generation
