Sika® Tite BE can be applied to the following substrates:

• Concrete
• Masonry
• Sand/cement screeds
• Fibrous cement sheeting
• Compressed fibrous cement sheeting
• Steel/Aluminium
• Timber posts

Sika® Tite BE must be cured for at least 48 hours at 23°C  (longer at lower temperatures.)

Sika® Tite BE must be cured for a minimum 3 days before coming in contact with water or any form of backfill.

Allow minimum 2 - 4 hours between coats at 23°C. Allow longer in adverse weather conditions. Drying time is dependent on ambient temperature and relative humidity.

1.0mm DFT- (Dry Film thickness): 7.5m2 per 15L pail

                                                                2m2 per 4L pail

All surfaces to be waterproofed must be firm, clean, dry, structurally sound and smooth. All grease, oil, wax, curing compounds, dust, loose material, laitance and other contaminants must be removed. The substrate surface must be continuous, all projections and rough spots should be dressed off to achieve a level surface. Sika® Tite BE can be mixed with sand and cement or pre-bagged mortar mix to form a screed to falls or patching render with improved adhesion and tensile properties.

Sheeting
Fibrous cement sheeting must be fixed in accordance with the manufacturer's installation directions.
Concrete
Concrete must be allowed to cure for 28 days and cement render and sand and cement screeds must be allowed to cure for 7 days prior to the application. Surfaces must be even and smooth, imperfections repaired with a suitable Sika^® MonoTop repair mortar.

Priming
Dry porous substrates must be primed using a dilute 1 part Sika® Tite BE to 3 parts water, work well into the substrate to ensure adequate penetration, avoid ponding. Allow to dry prior to general application. If moisture is present, allow for application of Sikalastic Moisture Seal, refer to PDS for application rates.

Single component, ready to use undiluted, prior to application thoroughly mix using a mechanical mixer to produce a homogenous liquid.

Remove liquid coating immediately with a dry cloth, clean tools and equipment with water while the material is still wet. Cured coating can only be removed mechanically.
