BOSTIK ARDATEC 2K FLEX

Two-Component Flexible Sealing Mortar (waterproofing)

BOSTIK ARDATEC 2K FLEX

BOSTIK ARDATEC 2K FLEX is a two-component (powder and liquid) sealing mortar. This product is waterproof and ideal for use in damp areas and underwater applications. Once cured, it offers excellent flexibility, stability, durability, and frost resistance. It effectively bridges cracks and protects against capillary water rise.

APPLICATION

• Composite sealing for ceramic tile coverings exposed to indirect and direct water contact (on walls and floors).
• Waterproofing of buildings at the points where they meet the ground.
• Waterproofing in damp areas such as showers, balconies, terraces, and swimming pools (both for internal water protection and around the tank area).
• Waterproofing for reinforced concrete basins from the positive side.
• Sealing connections between walls and floors (the sealing tape is embedded in the first layer of Adatec 2K Flex).
• Sealing of floor drains (using drains with pressed collars).
• Suitable for sealing installation penetrations.

FEATURES OF BOSTIK ARDATEC 2K FLEX

• Waterproof (suitable for damp rooms and underwater applications)
• Flexible
• Stable
• Frost-resistant
• Protects against capillary water rise
• Provides flexible composite sealing for ceramic tile coverings
• Strong structural waterproofing at points of contact with the ground
• Bridges cracks up to 0.2 mm
• Suitable for both indoor and outdoor use

INSTRUCTIONS FOR USE:

Pour the liquid component (5 kg) into a clean container, add the powder component (15 kg), and mix using a low-speed mixer until a smooth, homogeneous mixture is obtained. Apply the product in two layers to achieve the required sealing thickness. The first coat should be applied with a bench brush to the pre-moistened substrate. Before applying the second layer, the first layer must have gained its load-bearing capacity (approximately 3-4 hours). The product can also be applied using a notched trowel (4x4x4). First, spread the mixture with the toothed side, then smooth it with the flat side. Spraying machines can also be used. Each layer must be applied evenly. The minimum cured thickness of the sealing layer for all applications is approximately 2 mm (2.4 mm for the fresh layer) with a consumption of about 3.8 kg/m².

What is Waterproofing?

Waterproofing, also known as moisture insulation, involves protecting a structure from the harmful and destructive effects of water. Waterproofing solutions are classified based on the binder (waterproofing products):

• Bitumen and tar-based (an outdated method that is being phased out): These provide high water resistance and use readily available materials, but they have poor interlayer adhesion and negatively affect health.
• Synthetic resin-based (modern products): These are effective only in indoor, residential environments and are not suitable for waterproofing large water reservoirs because prolonged exposure to water reduces their effectiveness.
• Mineral-polymer waterproofing products: Unlike the previous types, mineral-polymer waterproofing solutions, also known as sealing or insulating slurries, do not have these drawbacks. Two-component mineral waterproofing is ideal for protecting walls, plinths, water basins, swimming pools, balconies, terraces, roofs, and rooms with high moisture levels, such as bathrooms and laundries.
• Multi-component reactive resin-based products (the latest binders): These can be products made from polyurethane or epoxy resins. They are characterized by good penetration into the substrate, ensuring high adhesion and complete waterproofing.
