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

questions Valerie Harle on 04/05/2019
Question: 

Can I use Sika1 to waterproof block paving driveway.

Answer: 

Sika 1 as a system does provide waterproofing but on a floor you would need to apply a 30mm screed for full waterproofing. We would recommend Hydron Mona-Guard Nhance be applied to block paving to provide a water and stain repellent finish.

questions Dave on 14/03/2019
Question: 

Hi which sika waterproofing admixture do I need to mix with my concrete sub base to stop water penetration? As you sell a ready mixed ve Dion of the sika1 also. Also mixing ratios for either product and quantity needed to order area as follows. 5m x 4m 150mm depth concrete. 5m x 4m 75 mm depth screed. Thanks

Answer: 

As a general waterproofer the Sika 1 Waterproofer Liquid Admixture should be applied at a ratio of 0.75 litres per 25kg bag of cement. We don't have a ready mixed version of this product.

questions peter on 21/11/2018
Question: 

what is the mix ratio for 3:1 sand and op cement for repointing eng. brickworrk?

Answer: 

Sika 1 Waterproofer Liquid Admixture can be added to a sharp sand and portland / good quality cement in order to make a waterproof render or screed. Typically this mix will be either 3:1 or 4:1.

questions Ron Killick on 23/10/2018
Question: 

Can Sika 1 Waterproofer Liquid Admixture simply be painted onto a damp wall/floor and seal them against moisture transfer. This is for a garage so does not have to be absolutely waterproof just help reduce ingress. Thanks

Answer: 

No, something such as Sika Damp-proofing Slurry may be more suited to your application.

questions Mike  on 21/02/2018
Question:
