Description
MasterLife 300D admixture is an integral crystalline capillary waterproofing admixture for concrete. It is designed for use in above- and below-grade applications. MasterLife 300D admixture meets ASTM C 494/C 494M requirements for Type S, Specific Performance, admixtures. A red-pigmented version of MasterLife 300D admixture is also available.
Applications Recommended for use in:
Foundations „ Sewage and water treatment plants „ Tanks „ Underground vaults „ Tunnel and subway systems „ Water reservoirs „ Secondary containment structures „ Below-grade parking structures „ Precast components „ Swimming pools
Features
Crystalline cementitious material
Integral addition
Reduces concrete permeability
Allows concrete to breathe
Benefits
Reduces penetration of water and other liquids
Seals hairline cracks
Resists positive and negative side hydrostatic pressure
Protects against sewage and industrial wastes
Performance Characteristics Setting Time:
MasterLife 300D admixture has little to no effect on concrete setting time within the recommended dosage range. Permeability: MasterLife 300D capillary waterproofing admixture is a portland cement-based crystalline cementitious material that reacts in concrete to form non-soluble crystalline hydration products in the capillary pores of the concrete. These crystalline hydration products effectively reduce the permeability of concrete thus reducing capillary absorption and the penetration of water and other liquids.
Guidelines for Use Dosage:
The dosage range for MasterLife 300D admixture is 2% to 2.5% by mass of cement. For most applications, the recommended optimum dosage of MasterLife 300D admixture is 2% by mass of cement. The dosage of the red-pigmented version of MasterLife 300D admixture is 2.5% by mass of cement.
Dispensing and Mixing: MasterLife 300D admixture is batched at the concrete production plant in a manner similar to that for cement or other cementitious materials. It may be batched in either a central or truck mixer. Follow the procedures outlined in ASTM C 94/C 94M, Standard Specification for ReadyMixed Concrete, for general batching and mixing instructions for concrete. Provide at least 5 minutes of mixing after the addition of MasterLife 300D admixture to ensure thorough and uniform distribution of the admixture in the concrete mixture.
Storage and Handling
MasterLife 300D admixture must be stored in a clean, dry area maintained at a minimum temperature of 45 ºF (7 ºC). MasterLife 300D admixture has a shelf life of one year when stored under recommended conditions
Packaging
MasterLife 300D admixture is available in 12 lb (5.5 kg) and 24 lb (11 kg) shreddable bags, and in 48 lb (22 kg) bags. The red-pigmented version of MasterLife 300D admixture is available in 15 lb (7 kg) and 30 lb (14 kg) shreddable bags.

MasterLife 300D by BASF is a high-performance acrylic-based polymer waterproofing coating designed to provide an effective barrier against water ingress in both new and existing structures. This flexible, breathable, and UV-resistant coating is specially formulated for applications on concrete and masonry surfaces exposed to moisture and weathering. It forms a seamless, elastomeric film that prevents water penetration while allowing substrate breathability.

Key Features:

Acrylic polymer-based, ready-to-use coating

High flexibility to accommodate minor cracks and surface movement

Excellent adhesion to cementitious substrates

UV-resistant and weatherproof

Resistant to alkalinity, efflorescence, and fungal growth

Allows vapor transmission – prevents moisture buildup beneath the surface

Easy to apply by brush, roller, or spray

Applications:

Roof slabs and terraces (flat or sloping)

Balconies and sunshades

Exterior walls and parapet walls

Masonry surfaces and RCC water tanks (outer surface)

Protective coating for concrete structures exposed to harsh weather

Technical Data:

Appearance: White or off-white liquid

Coverage: ~1.5 to 2 m²/kg for 2 coats (varies with surface condition)

Elongation: Up to 100%

Shelf Life: 12 months in unopened condition

Packaging: Available in 20 kg buckets
