Water leakage, dampness, and moisture penetration can create serious maintenance problems in residential, commercial, and industrial buildings. Bathrooms, balconies, kitchens, basements, swimming pools, lift pits, roof gardens, and other wet areas need a waterproofing system that is suitable for the actual substrate and exposure condition.
For these applications, ConSeal WS2 from Baral Chemical Company Ltd. offers a flexible cementitious waterproofing solution designed for concrete, masonry, and other suitable construction substrates.
ConSeal WS2 is a two-component polymer-based flexible acrylic cementitious coating. It combines a specially selected cementitious powder component with a liquid polymer component. Once mixed, the system forms a waterproofing slurry suitable for a wide range of wet-area applications.
What Is ConSeal WS2?
ConSeal WS2 is a two-component waterproofing coating formulated for concrete, masonry, and related construction surfaces.
The system consists of:
- Part A — Liquid Component
- Part B — Powder Component
The powder component contains selected cement, silica sand, and reactive fillers, while the liquid component contains polymer and wetting agents. Together, they form a flexible cementitious waterproofing coating.
It is also designed to create a barrier against water-borne salts and atmospheric gases.
Where Can ConSeal WS2 Be Used?
ConSeal WS2 is recommended for several waterproofing applications, including:
- Swimming pools
- Balconies
- Kitchens
- Bathrooms
- Damp areas
- Basements
- Roof gardens
- Lift pits
- Tile-cladding areas
- Damp-proofing applications
It can also be used as a backing coat behind marble, stone, and other mineral-based cladding to help resist rising moisture.
Key Benefits of ConSeal WS2
Suitable for Old and New Concrete
ConSeal WS2 can be applied to both existing and newly hardened concrete surfaces, provided the substrate is properly prepared.
Flexible Waterproofing Protection
The product provides elasticity and flexibility, which helps the coating accommodate limited movement within the system.
Low VOC and Non-Toxic
The product is described as non-toxic and low VOC. It is also stated as suitable for potable water tank applications.
Carbonation and Chloride Protection
ConSeal WS2 is designed to provide protection against carbonation and chloride exposure.
Positive and Negative Side Waterproofing
The system can be used for both positive-side and negative-side waterproofing applications.
Strong Adhesion and Breathability
The product is described as breathable, with very good adhesion, including adhesion on damp surfaces. It can be applied easily by brush and offers high coverage.
Crack-Bridging and Sealing Ability
ConSeal WS2 provides crack-bridging and sealing performance. It also offers protection against fresh water and seawater exposure.
Technical Performance
According to the technical data:
- Mixed Form: Slurry
- Colour: Grey
- Mixed Density: 2.00 ± 0.05 kg/L
- Toxicity: Non-Toxic
- Working Time: Apply within 45 minutes after mixing
- Setting Time: Minimum 1 hour in dry weather
- Water Absorption: More than 95% reduction compared with control
- Bond Strength: 1 N/mm²
- Water Permeability: Nil
- Crack-Bridging Ability: No crack up to 1.40 mm under the stated test condition
- Tensile Strength: 1.5 N/mm²
- Elongation: More than 60–70%
These values describe the tested product performance and should be considered together with correct substrate preparation and application.
Surface Preparation
Good waterproofing starts with proper surface preparation.
Before applying ConSeal WS2:
- The surface must be clean and free from dust, loose particles, oil, grease, curing compounds, mould-release agents, and other contaminants.
- Laitance should be removed using a stiff brush or blower machine.
- Damaged concrete should be cut back to sound concrete and repaired.
- Cracks and voids can be repaired using Gray Cementitious Alloy or cement-sand mortar modified with ConBond SBR.
Mixing Procedure
ConSeal WS2 is supplied in a fixed two-component proportion.
The mixing ratio is:
- 4 kg liquid
- 8 kg powder
The powder should be added slowly into the liquid and mixed using a low-speed drill and paddle until a smooth consistency is achieved.
Do not add water to a mixture that has already stiffened.
Only mix the quantity that can be used within approximately 30–40 minutes.
Application Method
ConSeal WS2 should not be applied directly onto dry concrete.
The substrate should first be saturated with water and brought to SSD condition.
A primer coat should then be applied using:
ConBond SBR : Water : Cement = 1 : 4 : 7
Each coat should be applied at a minimum thickness of 0.5 mm using a brush or roller.
The next coat should be applied after approximately 3–4 hours, and the second or third coat should be applied in the opposite direction to the previous coat.
Recommended Coating Thickness
For normal applications:
Total thickness: 1.5 mm
System: 2 coats + 1 primer
For hollow blocks or highly porous surfaces:
Minimum 3 coats
Total thickness: 2 mm
Curing
After application, the coated surface should be protected from:
- Strong wind
- Direct sunlight
- Rain
The surface should be kept moist for approximately 2–3 days.
Coverage
The approximate coverage is:
9–10 m² per set for two coats
Actual coverage depends on the condition and porosity of the surface.
Packaging
ConSeal WS2 is supplied as a 12 kg set, consisting of:
- 8 kg powder
- 4 kg liquid
Storage
The product should be stored in a cool and dry place and protected from direct sunlight and rain.
Why Use ConSeal WS2 for Wet Areas?
Wet areas require more than a basic surface coating. The waterproofing system must bond properly to the substrate and remain effective under repeated moisture exposure.
ConSeal WS2 offers a combination of:
- Flexibility
- Strong adhesion
- Crack-bridging ability
- Water permeability resistance
- Positive and negative side waterproofing
- Damp-surface adhesion
- Potable water tank suitability
- Low VOC and non-toxic characteristics
This makes it suitable for bathrooms, basements, balconies, pools, water tanks, roof gardens, and other wet-area applications.
Conclusion
A reliable waterproofing system depends on correct product selection, proper surface preparation, accurate mixing, suitable coat thickness, and correct curing.
ConSeal WS2 is a flexible, two-component cementitious waterproofing coating designed for bathrooms, balconies, kitchens, basements, swimming pools, lift pits, roof gardens, damp areas, and related applications.
Its technical properties include strong adhesion, low water permeability, flexibility, crack-bridging performance, and suitability for both positive and negative side waterproofing.
For best results, the surface should be prepared correctly, the product should be mixed in the recommended proportion, and each coat should be applied according to the specified thickness and curing requirements.
