    Our Hydraulic Lime Render Treatment Procedure

    Do you own a beautiful, architectural property of stone or brick? Is situated in a conservation area? Is the building listed, or does it have serious problems with the exterior fabric of your property?

    Did you know that you are not able to change the physical appearance of a building if your property is a listed building or located in a conservation area of natural beauty?

    Does your property suffer from :

    Hydraulic Lime Render applied to the exterior of a traditional property.

    Your local council will have to be informed, should any building work be carried out to the property. Especially considering that the appearance cannot be changed.

    Building control and regulations will instruct you to use like for like building materials.

    Most likely in properties of this nature the mortar used is either lime mortar, natural lime wash, hydraulic lime, lime crete and other materials such as polymer modified.

    Rendering solutions are not an option unless you are granted planning consent or permission from your local Council Planning Department.

    Hydraulic Lime Renders

    We use the types of hydraulic lime renders to suit the property. Hydraulic lime mortar mix for soft, chalky or crumbling brick or stone work. Slow setting, this is also suitable for internal masonry or sheltered areas.

    Advantages over cement

    By being produced at lower temperatures than cement, lime mortar requires less energy, resulting in 20% less CO2 output.

    Lime putty absorbs CO2 in the curing process. Non-hydraulic lime absorbs nearly its own weight in CO2, hydraulic lime, around 75% and lower.

    Lime mortar can be recycled. Unlike cement Bricks, using lime mortar can be recycled unlike the cement bonded equivalent which can only be used for hardcore.

    Strong, flexible, permeable

    Traditional buildings built using lime mortar move and absorb moisture.

    In comparison with cement mortar which is rigid, lime mortar ‘moves’ with the structure, thus preventing the masonry from cracking.

    By using lime mortar, expansion joints can be avoided.

    Likewise the imperviousness of cement mortar prevents it from absorbing water from the structure whereas lime mortar acts as a kind of ‘wick’, absorbing the moisture and allowing it to evaporate.

    By absorbing moisture, lime mortar is keeping the masonry dryer and lessening the risk of spalling.

    A super fast and efficient response from David who actually took the time to see the property rather then other contractors who rather lazily wanted a photo. Kept me informed along the whole process and his team were quick and clean. Would use again and would recommend!

    Had both front and back of the house rendered with acrylic silicone. A very professional job by a very hard working team who did not stop. David was professional in organising everything and the price was very reasonable. Very happy with the job and definitely recommend.

    Fantastic no hassle job completed by David and his team. This was 100mm insulation on a rented house. I was not on site all the time but could rely on a first class job. The tenant is delighted with a warmer house and reduction in heating bills just before the cost of energy increases!
