3/1 - suitable for internal building and pointing 3.5/1 - suitable for external building and pointing where a pozzolan such as Argical is to be added. Our premixed lime mortars are made from our own matured lime putty and a wide range of suitable coloured sands, enabling us to offer matches to existing lime mortar where required. We can supply lime mortar biscuits for you to match your own mortar or we are happy to give advice if you send us a sample of your mortar in the post. We do not make a charge for advice on matching the samples. For advice on the use of lime mortars and pozzolans, have a look at our "Repair Guidesheets" and "FAQs".

Coverage - 1 tonne of lime mortar will repoint 100-150 sq.metres of stonework. The 900kg bulk bags are designed for safe transport & unloading on a 1 tonne tail lift vehicle.

Our standard range of mortars are fully matured and available for immediate despatch. Specialist coloured mortars are typically used for pointing or bedding stone or brickwork where you need to match an existing or the local type of mortar. These mortars are made to order, typically with a 2-3 day lead time and some coloured lime mortars cost more than our standard lime mortars. Please click on the image for more details.

Lime Plaster
We supply our lime plaster in three formulas and a range of sizes. Both our 2/1 and 3/2 mix are suitable for final coat internal plaster skimming. The mix ratios mean ~ fine sand/lime putty, by volume. The 2/1 mix can be applied a little thicker and is suitable for internal finishes over lime backing coats. It can be sponged to give a slightly textured finish or trowelled smooth. Our richer 3/2 mix is better suited for ceilings and when skimming plasterboard. In the latter case it will be necessary to gauge the lime plaster with gypsum onto a drying initial thin coat of pure gypsum. We can also supply a special bonding coat for plasterboard called DG27. Our Regency mix is specifically designed to match historic ratios in the finest historic plasterwork.
Coverage - A 10 litre tub weighs 19 - 20kg depending on the mix ratio and covers 2 sq. metres at 5mm thickness, 3.3 sq. metres at 3 mm, 4 sq. metres at 2.5mm and 5 sq. metres at 2mm thickness.

Supplied in 19 & 20kg tubs and 500kg, 900kg and 1000kg dumpy bags with plastic bale liners.
Bulk Discounts: 2 - 3 tonnes ~ 5%, 4 - 9 tonnes ~ 10%, 10+ tonnes ~ 12.5%

Regency Lime Plaster - Now even better
A superior blend of our mature lime putty with fine sands and marble flour. This is suitable for creating exceptionally smooth trowelled finishes. For use as a final coat its applied over a first coat of our 3/2 fine lime plaster, having prepared the background with suitable backing coats of lime mortar. It can also be applied onto plasterboard or gypsum plasters providing these surfaces are primed with DG27 and after an initial skim of 3/2 fine Lime Plaster.

Coverage- Coverage- A 10 Litre tub weighs 18kg and covers 10 sq. metres at 1mm.

Lime Putty Filler
This is a pure white filler for those repairs where the 3/2 lime putty plaster is not appropriate. It comes in two grades and as a pre-coloured filler mixed to the same 54 standard colours as we supply our limewash in, to better match existing limewashed walls;
Fine for very thin hairline cracks that will feather in for seamless repairs.
Coarse for larger cracks up to 2mm. It can be pigmented if required or will take limewash or a breathable paint.

DG27
On occasion you may wish to finish gypsum plaster or plasterboard with a lime plaster to coordinate the look and decoration of a room. DG27 is a bonding primer that allows lime plasters to be applied over plasterboard or gypsum plasters. Plasterboard joints must be prepared as usual with scrim. DG27 is a thick liquid that can be diluted with up to 5% water if appropriate. It's painted on and dries in around 6 hours leaving a texture that's gritty like sandpaper and a little porous. The best grade of lime plaster to use with DG27 is our 3/2. DG27 can also be useful in consolidating a problem surface where you just want to apply a thin lime plaster skim e.g. where the surface was previously wallpapered or emulsioned.

Limecrete is a mixture of natural hydraulic lime (NHL) and aggregate that can be used to create breathable floors. It offers increased vapour permeability which is especially important for traditional buildings, and is often used in combination with breathable membranes. LECA (lightweight expanded clay aggregate) can be used instead of sand to create a warmer floor design. The LECA can be used both as a loose fill insulation under the limecrete slab and incorporated into the limecrete slab by mixing with NHLs. The LECA is available in a range of particle sizes and the NHLs in a variety of strengths. We offer practical advice on floor design. LECA can be incorporated to create an insulated floor to create a more comfortable breathable floor for a period property. Limecrete floors can also be used in conjunction with a modern insulation to conform to building regulations for new build or conversions.

We offer unbeatable bulk discounts on Natural Hydraulic Limes.

Natural Hydraulic Lime - BRECKWEG
We are the UK Distributors for Breckweg Natural Hydraulic Limes. These quality powdered limes are made in Germany and come in three grades - NHL2, NHL3.5 and NHL4.5. Both the NHL2 and NHL3.5 fully meet the minimum requirements of BSEN459:2001, the NHL4-5 isn't quite strong enough to meet the criteria for NHL5 but does offer a little more strength than the NHL3.5 - it's rated within the criteria for NHL3.5 as these figures are a minimum of a range of strengths. These NHLs are more lime rich than the French NHLs offering fattier mortar mixes with less greying of the mortar colour. They do take longer to set however and have a much lower final setting strength than the French NHLs so are best suited to internal or sheltered environments or where a lower setting strength is desirable such as pointing old brickwork.

They are supplied in 25kg moisture resistant bags and as the main UK distributors we can offer unbeatable prices.

Limewash

We make and supply our own limewashes based on a 50/50 blend of our own superior matured lime putty and water, together with both natural and manufactured pigments to produce a fantastic range of colours. We follow a traditional recipe of adding a little raw linseed oil which improves external watershedding and consolidates the surface a little. We make a particularly less watery limewash compared to a number of suppliers as our many customers prefer to buy limewash rather than water.

Our Limewash brochure extends our range to 54 fabulous colours at affordable prices, together with our traditional white. To see our Limewash Colour Chart please click here To see our full Limewash Price List please click here For our helpful guidesheets to applying limewash please click here We also provide a colour matching service for a fee of £20 + VAT. This is refundable on orders of over 100 litres. We provide 250ml sample jars of limewash for £1.00 plus postage, packing and VAT.

Coverage - 1 litre of limewash will cover 3 to 6 sq.m. for each coat, depending on the porosity and smoothness of the surface being limewashed. Four coats of limewash are recommended on new external renders and three coats on new internal plasters.

Riven and Sawn Lath

Click for larger view

We stock over 100,000 feet of lath all ready for repairing or creating lath and plaster walls and ceilings. Riven lath is hand split along the grain and is less flexible than sawn lath and offers a coarser surface for lime plasters to adhere to, making it more suitable for ceiling repairs. The key to the riven surface is then an additional grip to that formed by squeezing the lime plaster through the gaps between the laths. Typical lengths stocked are 3ft and 4ft in riven lath with 4ft, and 8ft lengths in sawn lath although other lengths may be available at times.   RIVEN SCOTCH PINE RIVEN OAK RIVEN CHESTNUT THICK SAWN OAK SAWN OAK SAWN LARCH price, per foot 24p 27p 27p 13p 9p 7p

Painting Equipment

Paint Pad
We are often asked for the best way of applying limewash. This can be down to personal preferences but a number of our customers find a paint pad ideal for smoother surfaces. They are faster and cleaner than using a brush. For various reasons we do not recommend a sprayer or roller, simply move the pad across the surface of the wall or ceiling in any direction to achieve the best finish. For rough surfaces use a large emulsion brush. Our 6" x 4" (152mm x 100mm) paint pads are a cheap and effective way to apply limewash and are excellent for use with our other emulsions and claypaints etc. Click here for better view of the the paint pad and refill.

The horse/cow mix is coarser and suitable for backing coats of lime render and lime plaster. Both the horse hair and goat hair are cut straight and bundled. The goat hair is white and very fine and can be used in final coat lime plasters if cut to shorter lengths. They are identically priced.
