A dry shake coloured or natural hardener for concrete.

Elite Crete colour hardener is a ready to use, dry shake material for colouring, hardening and finishing new concrete floors, walks, driveways and imprinted concrete. When mixed with water it may be plastered on the vertical surfaces of freshly placed concrete such as curbs, risers and planters.

Advantages:

•  Gives two and a half times the strength of untreated concrete.
•  Hardens and densifies concrete surfaces/floors.
•  Non rusting, can be used in a wet environment.
•  Resists moisture penetration, easier to clean.
•  Improved resistance to de-icing salts.
•  Increases the life of a concrete floor.
•  Available in many colours.

Coverage

For most applications a minimum of 25 kilos per 15m squared should be used for all standard colours. Light pastel or custom colours between 30 and 40 kilos per 10m squared. For heavier duty requirements up to 25 kilos per 10m squared may be used.



The following information is now provided for your reference.

Colours

Elite Crete colour hardener is available from stock in 16 colours. In addition custom colours can be formulated. Custom colours must be purchased in a minimum of 14 bags.

Composition

Elite Crete colour hardener is an intergrind of pigments dispersed with Portland cement combined with kiln dried silica. Colour and product uniformity is thereby assured. The pigments are lime proof and have maximum resistance to the effects of sunlight. The aggregates are selected for hardness and purity then carefully graded through a wide particle size range to produce a dense, wear resistant surface.

Benefits

Elite Crete colour hardener is designed to harden, densify and colour concrete floors and surfaces both inside and out. Concrete treated with Elite Crete colour hardener will be resistant to abrasion, dusting, spalling and deterioration. Elite Crete colour hardener floors will also be more resistant to water absorption and salts thus reducing cleaning and maintenance costs.

Technical Data

Compressive strength 44 N/mm squared. Tested to BS1881:Pt.202:1986

The colour hardener test was carried out by SGS United Kingdom Ltd. to prove that our colour hardener is suitable for the application of pattern imprinted concrete and in particular increases the strength and surface tension of ordinary concrete.

The colour hardener in this test was applied at a rate of approximately 1.75 kilo per metre, each 25 kilo bag covering approximately 15 square metres.

The mean rebound number for ordinary concrete was 14, giving a compressive strength of 18 N/mm squared. After application of our colour hardener the compressive strength increased to 44 N/mm squared, two and a half times the strength of untreated concrete.

Concrete Mix

The process requires the addition of a colour hardener, therefore it is not usual to go for a high cement content mix. 30-35 kn. mix is the norm, slump should be around the 100mm mark. Air entraining agent should be included at all times where freeze thaw cycles occur. We also recommend the use of fibres to inhibit cracking.

Sealing

To enhance the natural colours we recommend a coat of Elite Crete Acrylic Concrete Sealer. This not only gives protection against oil stains etc., but prevents dusting and cuts maintenance down to a minimum.
