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.

For the scratch coat onto lath ceilings we also supply a double haired mortar. 3.5/1 - suitable for external backing coats of render. Our haired lime mortars are premixed and matured and use a traditional, natural animal hair not polypropylene. The haired mortar needs to be used within 2 - 3 weeks as the hair will gradually dissolve in the alkaline mortar - you will end up with an unhaired lime mortar! This is still usable if you tease extra hair into the mortar.

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 wall 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 scrim the joints of bare plasterboard as usual with a very thin coat of gypsum to secure the scrim tape, alternatively lime wall finish smooth may be used. The primer DG27 should then be applied over the whole surface. Our Regency plaster offers the smoothest of lime plaster finishes and 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%, 10% for full 45 x 17-20kg tub pallets

Regency Lime Plaster
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. For details of case studies and methodology please click here For a technical sheet on LECA based limecrete please click here For a technical sheet on sand based limecrete please click here

LECA
Widely used in horticulture and with cement for flooring, Light Expanded Clay Aggregate is ideal mixed with NHL for use with limecrete floors as an insulating sub-base beneath ground floors or as a light weight aggregate in slabs. It consists of lightweight, porous, ceramic granules formed by expanding special clays at high temperatures. In bulk, the coated version of LECA is free-draining and has negative capillary action, good load-bearing properties and good thermal qualities (k = 0.11 w/mk).

Natural Hydraulic Lime - Hanson-Castle
We are Main Distributors for Castle Natural Hydraulic Limes, recently rebranded as Hanson lime. These powdered limes come in three grades - NHL 2 ( feebly), NHL 3.5 (moderately) and NHL5 (eminently) hydraulic. These quality NHLs are made in France and fully meet the requirements of BS EN 459:2001. Natural Hydraulic Limes are mixed with a suitable sand to make hydraulic lime mortars which set in the presence of water - hence the term hydraulic. These French hydraulic lime mortars are relatively quicker setting and have a higher final setting strength compared to the UK NHLs and therefore they are more suitable for exposed environments.

They are supplied in 25kg moisture resistant bags and due to our bulk purchasing power we can offer unbeatable prices.

Natural Hydraulic Lime - Singleton Birch
These are supplied in 25kg moisture resistant bags and as a main UK distributor we can offer very competitive prices. We are a supplier of the Singleton Birch range of British made NHL's complementing our existing range of quality NHL's at unbeatable prices. Singleton Birch 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.

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 To see our full Limewash Price List For our helpful guidesheet to applying limewash 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.

These are suitable for the repair and rebuilding of earth buildings. We supply two types - compressed and extruded. The compressed cob blocks more closely match the original composition of the sub-soil used for cob buildings, the extruded cob blocks are slightly smaller and a bit cheaper! Coverage - a cubic metre of wall rebuild will require 80 cob blocks 18" x 9" x 4" Bedding mortar - a tonne of 4/1 lime mortar will bed around 160 cob blocks.

Oak Lintels
We stock are wide range of seasoned oak lintels that have been air dried for up to 3 years. Standard sizes are 4" x3", 6" x 4", 8" x 5" and 12" x 5" in a variety of lengths up to 7ft. We can also supply green oak cut to your specific requirements.

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. Coverage: Allow 80ft per m2 for riven lath and 94ft per m2 for sawn lath plus any wastage if the joist centres are not spot on for the lengths available   RIVEN SCOTCH PINE RIVEN OAK RIVEN CHESTNUT THICK SAWN OAK SAWN OAK SAWN LARCH price, per foot 24p 27p 27p 13p 11p 8p

Galvanised Lath Nails
We stock 30mm nails, there are approximately 1000 of the 30mm length per kg.

Hessian
Hessian sheeting helps to protect lime mortars from rain, sun and drying winds. In combination with tarpaulins they can also give frost protection. Please note that this is a high quality sheeting, not like some of the poor quality hessian that can be obtained.

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. Be careful not to leave lines as you apply the limewash, so make sure that you apply it wet on wet and move the pad in several directions for best results. 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 Harris Taskmaster emulsion block brush large 824. 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.

We supply a wide range of natural animal hair for teasing into lime mortars. They are added when lime putty and sand are mixed to make lime mortars for internal plastering and external rendering. 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.
