Polyurethane, protective deck coating Description
MASTERTOP 1330 is a tough, durable, polyurethane deck coating system, which provides a seamless and protective, waterproof, wear resistant, smooth or skid-resistant surface.
The system comprises a unique combination of polymers which incorporates:-
- MASTERTOP PRIMER 2 - Is a solvent free, two component, low viscosity epoxy preconditioning coat/primer, which stabilises the prepared substrate; acts as the bonding media for the aggregate key, and isolates subsequent PU coatings from the alkalinity of concrete, which is known to assist degradation of polyurethanes. MASTERTOP PRIMER 2 exhibits a high degree of capillary-pore penetration and will prevent rising damp from reaching subsequent coatings.
- Mastertop SRA No. 3 - A graded, high purity quartz aggregate with a particle size in the range 0.3 –0.9mm. Used as a multi action: mechanical key, wear enhancer and to provide skid resistance, it's use is the means by which thickness is attained with economy for the various wearing conditions such as: in traffic lanes, ramps and turning areas.
- MASTERTOP TOP COAT 40P - Is a one component PUR coating compound with a low solvent content suitable for, among other things, top seals in parking decks. It provides UV-resistant, hard-elastic surfaces which are resistant to chemicals and abrasion.
Primary uses
MASTERTOP 1330 may be specified as a waterproof and protective wear resistant membrane for a variety of applications including:
- Car park decks
- Trafficable flat roofs
- Ramps
- Plant rooms
- Stadia seating, bleachers
- Balconies
- Protects concrete from the damaging effects of salt water, de icing salts, chemicals, fuel and oil spillage.
- Non skid, decorative, crack bridging, easily maintained surface enhances durability of the substrate concrete.

Guide to application
Preparation:
Remove laitance, weak or friable concrete and all contaminants that could affect the bond to the substrate.
Suitable preparation includes light grit blasting, surface grinding etc. Surface defects should be repaired using CONCRESIVE 2200 or other suitable repair compounds from the CONCRESIVE or EMACO range.
Priming:
Mix and apply MASTERTOP PRIMER 2 surface conditioner to the prepared dust free surface at approximately 0.2-0.3kg/m². Into the wet primer, scatter 0.5kg/m² SRA No. 3.
Note: If a smooth surface finish is required, omit the aggregate scatter.
Allow to dry.
Application
- MASTERTOP TOP COAT 40P should be stirred before use to ensure uniformity of colour.
- Apply by roller, trowel or airless spray to the primed tack free surface.
- Apply at the rate of 0.3-0.8kg/m² per coat with a minimum of 0.6kg/m². MASTERTOP TOP COAT 40P can be applied as a single coat, or as a multi coat sandwich system incorporating aggregates to give a slip resistant finish. When applying as a top coat or part of a multi coat system, do not exceed the maximum overcoating times of the previous coating.
- Do not apply when the humidity exceeds 90%. Ensure that the substrate temperature is 3°C higher than the dew point.
Chemical resistance
MASTERTOP TOP COAT 40P is resistant to acids and lyes of medium concentrations, mineral oil products and solvents. Contact your local BASF office for specific details.
