Would this product erode or damage aluminium?

Due to aluminium being non-ferrous, if applying Fosroc Conbextra GP to this surface type it shouldn't corrode, and due to being essentially a concrete based product, this is inert once cured. We would recommend to test on a small area prior to full application.

Would this product be suitable for repairing damage in approx 1m square of a concrete slab

This product is a high-flow, non-shrink, cementitious grout normally used for repairing joints, reinforcing steel bars where pouring access is restricted. Please can you provide more information on the area to be repaired with pictures of the area to technical@rawlinspaints.com

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

Limitations

Low Temperature Working:

When the air or contact surface temperatures are 5°C or below on a falling thermometer, warm water (30°C to 40°C) is recommended to accelerate strength development
Substrates should be free from ice
For ambient temperatures below 10°C the grout consistency should be flowable and the formwork should be maintained in place for at least 36 hours
Normal precautions for winter working with cementitious materials should then be adopted, specifically protecting the grout from freezing in the first 48 hours after placing

High Temperature Working:

At ambient temperatures above 35°C the mixed grout should be stored in the shade
Cool water (below 20°C) should be used for mixing the grout
