Frequently Asked Questions
A breathable membrane, preferably a hessian sheet, should be used to cover and protect the repair from sunlight, wind, cold and rain. In temperatures above 10°C the hessian should sprayed with water so that it doesn’t cure too quickly. In direct sunlight a physical barrier can also be placed in front of the repair to cast shade.
If you see any lumps in the dry mortar when you open the container, simply break them down using some light pressure before adding water.
Yes. As a free service, if you send in a sample of the material that you want to colour match, we will look through our range of colours to see if we can get a match. If we are unable to get a match from our range, we can create a custom colour at an additional cost of £25.
Sorry, no we cannot. Something as simple as the brightness of the screen we view it on could mean the wrong shade or colour. If you require us to match the colour then please send in a small sample. A piece the size of a 1p coin should suffice.
You will require approx. 3kg of mortar per SQM of repointing at 10mm depth in brickwork and 5KG of mortar per SQM in random stonework.
You allow approx. 1 litre of water with every 7 – 9 kg of dry material. So roughly 1 part water to 7 – 9 parts powder.
Yes. Build up the repair in layers of no more than 10mm to 20mm per layer. For the very first layer, make the mix slightly wetter than normal, about the consistency of smooth peanut butter. This will help with bonding and adhesion. Allow each layer to dry (it does not have to fully cure) and scrape back any skin that has formed on the surface to assist bonding.
