Product information.

Non-hydraulic lime mortar & lime plaster (backing coat).

This lime mortar is used for general building and as a backing coat for traditional lime plaster. The mortar is a mix of fat lime putty and coarse aggregates. The lime, grit and aggregates are all best quality natural materials from England and the UK.

The material is packaged in a tough, reusable tub that is portable and convenient to store. Lime Putty Mortar sets by carbonation (on contact with air) so the material has a long shelf life if kept sealed, air-tight in its tub. As it dries it can be knocked up again, this is done by beating it with a stick to make it workable again.

All of our lime putty mortars come complete with instructions and technical support. We don't just supply these materials, as a stone masonry and restoration contractor we have been using them for more than twenty years. You can call our stonemasons any time for friendly, expert help and advice.

Please bear in mind though! This is not like a modern cement mortar or render. Lime Putty Mortar is knocked up, not mixed. Once placed, the mortar must also be cherished, keeping it moist, this wet curing process helps to prevent cracking (shrinkage).

If you're not comfortable with this then please try our Natural Hydraulic Lime (NHL) Mortar. It has all the benefits of a lime putty mortar but none of the complications. NHL mortar is similar to modern cement based mortars to mix and it's a beautiful material to use. If you're looking for a lime plaster, NHL2 Lime Mortar makes the best hydraulic lime plaster.

Mortar matching service.

A lime mortar mix to match existing mortar on your building.

We can pre-mix your lime mortar to match an existing mortar. The sands and aggregates in the material can be varied to match the colour and texture of most mortars precisely. With a good match your repointing will blend seamlessly with the rest of the masonry on the building. You won't get the mortar banding or striping that you sometimes see when parts of a wall or building are repointed.

This service costs £35 including VAT. You will need to supply us with a small mortar sample from your building and a mix reference to identify your mortar mix.

From then on, whenever you add mortar to your cart you'll be able to choose from any mixes you've had matched. We'll show you a list of your mix references to choose from. The matched mortar costs the same as the standard mix, you only pay for the matching service initially.

Matched lime mortars are usually shipped in 2 to 3 days but in some cases it might take a bit longer. This all depends on the availability of the sands and aggregates when you place your order. Please remember this if you are planning a building project, we advise you to allow 10 days to cover the worst case scenario.

If you're interested in this service then please make an enquiry, we'll get back to you promptly with more information. Please include your mix reference in the enquiry, something that is easy for you to remember and identify later. If you're a builder or contractor we recommend you use the project as a reference eg.
