Rendercote is based on our best understanding of the probable mix used for the high relief stucco work at Hardwick Old Hall in Derbyshire, a lime plaster finish exposed to the elements since the mid eighteenth century. Rendercote is based on blend of limestone aggregates, sourced mostly from the Buxton area. It is combined with a moderately hydraulic lime and natural stearate to repel liquid water but allow free transport of water vapour. It is for use only for masonry backgrounds and is intended as a robust two coat system for high exposure areas such as parapet walls, chimneys and plinths, as well as windmills and lighthouses.
To find out more information about the applications of Rendercote as a lime plaster finish for your projects, get in touch with Best of Lime today.
A 25kg bag of Rendercote will cover approximately 1.7m2 if used at 10mm thick. This applies to both Base and Finish.

Water first, clean, no more than 6 litres to start, more can be added if a wetter consistency is required. Next add the plaster - Rendercote can be mixed with a paddle, a standard drum mixer or a pan mixer. Be careful when adding the plaster not to create excessive dust, or splash back. Eye protection must be worn at all times when handling lime. Lastly, add the fibres from the small bag contained in the 25kg bag. The fibres should be added gently, though it is not necessary to 'tease' them in. Rendercote is not for use on lath, or a timber framed background, please see Warmcote and Limecote. Dubbing out of damaged masonry can be done best by mixing the Rendercote Base slightly stiffer (less water), ensuring that the full amount of fibres have been added. Once filled to flush, apply a light scratch to the face of the repair. Overall, Rendercote Base and Finish are intended as a 20mm system. Once any dubbing out has been carried out and the repair has set to ‘green hard’ (hardened, but not dry), apply a 10mm coat of Base and scratch to give a good key. Once the scratch coat has hardened off, but not dried, apply the 10mm of Finish. The final coat is best finished with a steel trowel to a smooth, closed finish. In high exposure areas, it is recommended to decorate with a mineral paint system, giving greater, long lasting protection than a traditional lime wash.

Rendercote is packaged in 25kg re-granulated LDPE bags that are fully recyclable. A maximum of 40 bags can be placed on a pallet and shipped on a national pallet network. We have no minimum order quantity: you can order as many or few bags as you like. We can deliver to the whole of the UK. For a smaller quantity (1-3 bags), we would normally despatch these in boxes via Parcelforce/DHL. The cost is generally governed by the number of packages. Anything more than 1-3 bags would go onto a pallet, up to a maximum of 40 bags per pallet (1 tonne). This will be a tail lift delivery, effectively dropped at the kerb/lorry side where safe. Please advise us of any special delivery instructions, as we will not be held responsible for any issues arising at the delivery point. The drivers will work with you to get your pallet delivered safely and effectively. Pallet delivery costs are priced per pallet and are postcode driven, and we can offer additional services such as AM delivery and timed delivery. All are chargeable extras. This is a service that we pass on the cost that we pay - we do not make any money out of this service and we do not charge for the pallets. The other option is collection from us in Haverhill: again, this needs to be booked in. Because of lead times and safety concerns, we cannot currently accept walk-ins due to the current situation.
"Limecote and Warmcote are ideal products for use on timber framed buildings and low strength substrates with their excellent flexibility, bond, and light weight compared to sanded plasters. Being dry bagged makes it easy to transport and store, with the added advantage of being able to adjust the mix to suit thin or very thick coats without compromising the product, or the quality of the finished work."
"Best Lime plaster system on the market!! I found this accidentally due to the coronavirus pandemic as stocks of everything ran out, and it's changed the way all of the plasterers in our area are now plastering conservation listed buildings as well as new builds... due to its unique formula and characteristics of extremely quick application, drying, workability and breathability. It's rare to find such a great product and more importantly a great level of customer service in the build industry."
"As self-builders of a very large community project, Limecote has been an outstanding product, making all the difference to our progress. It keeps well in sealed bags even outside; it mixes easily and safely; being half the weight of sand-based products, it is easy to carry and apply to the walls; excellent adhesion mean that less is dropped and wasted... and not having to constantly limewash going forward make it a no-brainer."
