ColourPicker Explained

In general we sort colours for products into 2 main groups - ‘Ready Mixed’ and ‘Tinted’.
Tinted colours will always be more expensive than Ready Mixed colours as they need to be produced at the time of order using a tinting machine dispensing colourant into a base*.
During busy periods, this means that tinted colours could take longer, for example – a ready mixed colour ordered on a 3-5 day delivery might arrive within 3 days, however a tinted colour might take the full 5 days to arrive.

To find Ready Mixed colours, search "ready mixed" or select the Ready Mixed 'colour chart'. To see Tinted colours select a colour chart such as RAL, BS, NCS, etc. or search for a colour/hue to see available or related options.

To ensure fair pricing, we split colours into ‘Price Bands’ to group together similar priced colours. If you wish to search for the cheapest tinted colours, always select Price Band 1.

We make every effort to list all available colours, however we also offer a colour match service which can be accessed by contacting our Technical Team on 0113 245 5450 (option 2) or emailing [email protected]

*Colours are sold in the nearest tin size but actual paint volume per tin may vary up to 10% depending on colour

Colour reproduction of the Products on the Site is limited by the technology used to deliver web pages and by the colour representation of Customer’s own monitor and computer set-up. We have made every effort to display as accurately as possible the colours of our Products but we cannot guarantee that the colour shown on Customer’s monitor’s display will accurately reflect the colour of the Product on delivery. We recommend that Customer first purchases the smallest Product available or access an industry standard colour chart in person (and not digitally) to ensure that the colour is acceptable for its purposes.

Substrate Quality

The surface must be sound, of sufficient strength, clean, dry and free of dirt, oil, grease and other contamination
The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm²) with a minimum pull off strength of 1.5 N/mm²

Substrate Preparation

All surfaces to be coated should be thoroughly cleaned by conventional means
Inspect the substrate
Spalling, flaking or damaged areas should be repaired using compatible materials to match surroundings or replaced as necessary
If in doubt apply a test area first
Tiles must be prepared mechanically; glazing must be removed
Grinding may be necessary to level the surface
For detailed information regarding substrate quality / preparation and primer chart please refer to the Product data Sheet

Application Instructions

Mixing

Part A : Part B = 3.4 : 1 (by volume)

Application Method / Tools

Prepare Sika Concrete Primer LO by mixing component A until uniform
Add the component B into component A container and re-mix until homogeneous
Sika Concrete Primer LO can be applied by short-piled roller or brush
Allow primer to dry sufficiently (see waiting time / overcoating) before overcoating

Potlife

Sika Concrete Primer LO is designed for fast curing
High temperatures combined with high air humidity will increase the curing process
Thus, mixed material in opened containers should be applied immediately
In opened containers, the material will form a film after approx. 30 minutes

Waiting Time / Overcoating

At 20°C:

Minimum waiting time: 30 minutes
Apply an additional coat if more than 24 h pass before coating
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity

Notes on Application / Limitations

Do not apply Sika Concrete Primer LO on substrates with rising moisture
Do not use Sika Concrete Primer LO for indoor applications
Protect freshly applied Sika Concrete Primer LO from damp, condensation and water for at least 24 hours
Do not apply close to the air intake vent of a running air conditioning unit
The incorrect assessment and treatment of cracks may lead to a reduced service life and reflective cracking (for further information please contact Sika technical service)
If heating is required do not use gas, oil, paraffin or other fossil fuel heaters, these produce large quantities of both CO² and H²O water vapour, which may adversely affect the finish
For heating use only electric powered warm air blower systems
Allow new concrete to cure/hydrate for a minimum of 10 days prior to application, preferably 28 days
