Product Details

Traditional lime render, 100% natural, no artificial additives. Designed and manufactured to British Standards following English Heritage guidelines. The lime, sands and aggregates are carefully selected and sourced from England and the UK.

The render is a ready mix, it is already knocked up. It will eventually start to harden (even inside the tub) but can be knocked up to a workable state again and again.

This unique characteristic gives non-hydraulic lime render a long shelf life providing that it is kept sealed air tight. The mortar starts to set when exposed to air for a period of time, it can't be knocked up again once it sets.

Lime renders from Conserv come complete with clear, concise instructions and free technical support. You can call us any time for friendly, expert help and advice.

Frequently Asked Questions

What is non-hydraulic lime render?

It�s a traditional lime render, it does not contain any cement. It is a composition of lime putty and aggregate. Lime putty is a non-hydraulic lime, hence the name.

Do I need to add cement to make it set?

No, you should never add cement to a traditional lime render. Non-hydraulic lime mortars set more slowly and remain supple by nature.

Can I add cement to make it set faster?

No, don't add cement for any reason, ever. The addition of an OPC cement defeats the purpose of using a natural lime render. It detracts from the render's initial benefits.

What is a non-hydraulic lime?

The term non-hydraulic refers to the lime's setting characteristic. Non-hydraulic lime sets by carbonation as opposed to hydrolysis which is how hydraulic lime sets.

Cherishing (moisture control) is key to successful applications of non-hydraulic lime mortars & renders.

Hydraulic lime render is ideal if you're on a tight schedule. Equally traditional but skip the traditional techniques.
