Everbuild 202 Integral Waterproofer 5L

Everbuild® 202 Integral Liquid Waterproofer – 5 L

Air-entraining, liquid-gel admixture in a 5 L container. Designed to significantly reduce water permeability in mortar, renders, screeds, and concrete mixes—delivering long-term protection from water ingress while enhancing workability and strength.

Key benefits

• Reduces surface absorption and decreases permeability of mortar and concrete mixes.
• Contains air-entraining agents—preserves mortar flexibility and prevents stiffness.
• Ensures workability, easier application, and increases compressive strength.
• Non-corrosive—safe for embedded steel reinforcement.
• Low toxicity and freeze-stable to approximately −10 °C.

Typical applications

• Waterproofing below-ground structures (basements, foundations).
• Waterproofing above-ground renders, screeds, and mortar surfaces.
• Rendering tank linings, silage pits, ponds, pools, and external applications.

Usage guidance

• Add between 0.5–1 L per 100 kg of cement via gauging water, or mix one part product into 20–40 parts water.
• Adjust water content down by up to 20% to maintain proper consistency.
• Rendered mixes: use 3 parts sharp sand to 1 part cement for below-ground works; for external render, use 4.5 parts sand to 1 part cement in two coats at 18–20 mm thickness.
• For pool and tank linings: 3 parts sand to 1 cement mix; apply 18–20 mm on walls and 35–38 mm on floors, with staggered joints and coving in corners.
• Always use stiff gauging mixes to minimise cracking.

Good to know

Not suitable for structural concrete or as a direct substitute for DPC systems. Does not repel surface water—use Everbuild® WATERSEAL for that. For tanking applications, combine with an Everbuild DPM system.
