Product Details

Hydraulic lime mortar, 100% natural, does not contain any artificial additives or plasticisers. 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 material is packaged in a tough, reusable, water-tight tub. This makes it clean, portable, easy to handle and convenient to store. The lightweight tubs are ideal for small maintenance and repair projects.

Mixing the mortar is really simple. The hydraulic lime is separated from the aggregate inside the tub in a high tensile bag. All you need to do is empty the bag of hydraulic lime into the tub with the aggregate, add clean water and mix the materials to the correct consistency.

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