CEM 2K BS

Two Component Acrylic Modified Flexible Cementitious Waterproof Coating

CEM 2K BS is a versatile two-component, cementitious waterproofing compound formulated with advanced acrylic polymer technology. It is designed for use in areas where substrates are subjected to movement and require crack-bridging properties. This coating offers superior flexibility and water resistance, making it ideal for various waterproofing applications.

Key Features
  • Flexible: Accommodates normal building movements and hairline cracks.
  • Pressure Resistant: Resists both positive and negative pressure.
  • UV Stable: Can be left exposed without degradation.
  • Easy Application: It can be applied with a brush, roller, or spray.
  • Water-based: Safe to use, low odor, and easy to clean.
  • Excellent Bonding: Adheres well to concrete, masonry, ceramics, and most commonsubstrates.
  • Self-Priming: No additional primer is required.
  • Non-toxic: Safe for internal waterproofing of potable water tanks.
  • Vapor Permeable: Allows water vapour to escape from the substrate.
Application Instructions Surface Preparation

Ensure the surface is dry, clean, structurally sound, and free from oil, grease, wax, polish, laitance, dust, and other barrier materials. Treat all vertical bore packing with Carbolink's SG Grout and horizontal bore packing with polymer-modified mortar admixed with Carbolink's CreteBond. Install covings using polymer-modified mortar mixed with CreteBond if required.

Mixing

Thoroughly stir the liquid component and pour it into a suitable mixing vessel. Slowly add the powder while mixing with a spiral mixing paddle in a slow-speed drill. Continue mixing until a consistent, homogeneous mix is achieved.

Application

Saturate the surface with clean water. Apply the first CEM 2K BS coat using a short, stiff bristle brush or roller while the surface is wet but free of standing water. Allow the first coat to dry for 2 - 3 hours before applying the second coat at a right angle to the first. Let the membrane dry entirely before applying tiles or other finishes.
Application Thickness Per Coat: Approx. 0.6mm Coat Consumption (min 2 Coats): Approx. 24 m²
Consumption 2 of 2 Coats (kg/m²): Approx. 1.7 kg (depending on substrate condition)
