Description
Sika 1 Waterproofer Liquid Admixture is an aqueous solution containing complex colloidal silicates. In the presence of water these swell and block the capillaries and pores in the applied sand/cement renders, screeds and mortar to provide an effective barrier against the transmission of liquid water.
Sika 1 Waterproofer Liquid Admixture is used with Sika 1 Structural Waterproofing System mortars which are pre-bagged, kiln dried blends of specially graded aggregates and cements packaged in 4 grades at the appropriate mix ratios for optimum application performance and durability. When mixed with the diluted Sika 1 Waterproofer Liquid Admixture they provide the multicoat components for the structural waterproofing systems.
Sika 1 Waterproofer Liquid Admixture can be added in measured quantities to Sika mortars to create;
- Structural waterproof renders to resist water pressure below ground
- Structural waterproof screeds to resist water pressure below ground
- Waterproof renders to resist moisture and dampness above ground level
- Internal waterproof tanking
- General waterproofing admixture for mortar
