Stock and plant rooms
Workshops
Ammonium nitrate storage

Features and benefits

Adjustable rate of cure – accelerator can be added for low temperature cure.
Chemical resistant – excellent resistance to acids and alkalis.
Low VOC emission – environmentally friendly.
Low odour – does not taint food.
Matt finish.
Colour availability – available in a range of colours.

Application guidelines

Summary from the data sheet — follow the PDF on site.

Concrete coating

The concrete substrate should be firm, clean and dry.
The compressive strength of the surface must be a minimum of 25 MPa and the surface tensile strength a minimum of 1.5 MPa.
New concrete is to be a minimum of 7 days old. The surface of the concrete will need to be mechanically prepared by either diamond grinding, shot blasting or scarifying. All weak and loose material, surface laitance, contaminants and coatings or curing compounds must be completely removed. It is preferred that the prepared surface has a profile to ensure both excellent chemical and mechanical adhesion.

Mixing

Mix components A and B together for 30 seconds. Add aggregate bag and mix until a smooth consistency without lumps is achieved, 1–2 minutes should be sufficient.

Hycrete PU-TC(m) is specially designed as a topcoat for Hycrete PU-SL(m) and TR flooring systems.

It can also be used as a stand alone concrete coating. It has excellent chemical resistance properties.

Application

Do not apply over damp or wet surfaces. Do not apply where there is water vapour transmission.

Non-slip finish

Apply to substrate and broadcast anti-slip aggregate into the wet surface and allow to cure. The size of the aggregate that is used depends on the level of slip resistance required.
Apply a second coat of Hycrete PU-TC(m) to seal the surface.

Keep in mind not to flood the surface so much as you lose the slip resistant effect of the aggregate.

Hycrete PU-TC(m) may also be applied over either a self-levelling or broadcast Hycrete PU-SL(m) topping.

Coverage

The following information is a guide only.

Over a smooth surface the expected coverage is about 4–5 m²/litre. When applied over a broadcast surface the consumption will depend on the profile, however, approximately 2 m²/litre can be expected.

Packaging

Hycrete PU-TC(m) is a 3 component product consisting of a resin, hardener and blended fillers. This is usually sold as a neutral kit requiring a 175g pigment pack.

Component breakdown:

Part A	1 kg
Part B	1 kg

Part C Aggregate 1.25 kg

The mixed product will yield approximately 2.35 litres.

Limitations

Hycrete PU-TC(m) is an industrial flooring finish which may discolour on exposure to UV light from the sun or an artificial source. The severity of discolouration is dependant on colour choice. Any such discolouration has no effect on the performance of the product.

Shelf life

This product has a shelf life of 9 months from date of manufacture, stored away from sunlight at 25°C in original un-opened container.
