BETEC™ Seal SC
Two-compound, cementitious coating for waterproofing of new and existing non-exposed non-critical applications
BETEC™ Seal SC Liquid used with BETEC Seal SC Powder reacts with concrete by process to form a two-part, permanent, slightly flexible, BETEC Seal SC waterproofing system.
BETEC Seal SC Liquid being a milky white, carboxylised styrene butadiene latex liquid, is used with BETEC Seal SC Powder to improve workability in the mix in order to achieve optimum adhesion to the substrate, to improve elasticity and control shrinkage on setting, to avoid early water loss during the setting process, and to avoid salt efflorescence and increase abrasion resistance.
- Rigid basement walls and floors
- Bathroom, balcony, wet area and planter box
- Lift pits
- Concrete tanks
- Concrete water-retaining structures
- Monolithic concrete planter boxes
- Resists both positive and negative water pressure
- Easy application, fast mixing by paddles
- Low water absorption and good water resistance
- Good adhesion to correctly prepared concrete, masonry and rendered substrates
- Pre-stir the BETEC Seal SC Liquid before mixing.
- Always add the BETEC Seal SC Powder to the BETEC Seal SC Liquid. The mixing time is approximately 2 – 3 minutes.
- DO NOT USE PART MIXES. DO NOT ADD EXTRA WATER, CEMENT, SAND OR OTHER MATERIALS TO BETEC SEAL SC.
The substrate before waterproofing must be sound, clean and free from irregularities, sharp projections, loose particles, dirt, oil and contaminants. Brick and masonry surfaces shall be smooth and joints shall be filled with cement filler.
BETEC Seal SC is applied in two coats using brush or trowel. Apply the first layer only horizontally, and then apply the second layer only vertically. Alternate the direction for subsequent coats.
Leave each coat to Leave each coat to become tack-free (2 to 6 hours depending on climatic conditions), then apply subsequent coats at the same thickness / consumption rate as the first. Avoid damaging the first coat during application of the second coat.
Clean all brushes, rollers, trays, mixing containers and surrounding areas with clean water before the product sets.
