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.

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 New lower prices
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.

LIGHTWEIGHT AGGREGATE
The Clay Aggregate has a wide number of uses in horticulture and the building industry; it even gets used in bee keeping. When used in the build up of a Limecrete floor, the coated clay insulation is free-draining and has negative capillary action, good load-bearing properties and good thermal qualities (k = 0.11 w/mk) it should be used under the slab and the uncoated clay aggregate is mixed with a binder to create an insulated and breathable slab.

All prices are plus carriage, although the 50 litre bags are available ex-works. The weight varies due to the variation in moisture content.

	Technopor Perimeter 50 is a lightweight, breathable looselay aggregate made from recycled glass. It is used in the same way as the coated clay aggregate but differs as it is capable of being used as a load bearing hardcore and has better lamda value, so needs less depth for the same thermal performance. Lamda thermal performance of around 0.08, this has about 20% better thermal performance than the clay aggregate.
Looselay loft insulation	Limecrete base with geotextile membrane	Dealing with flood prone buildings	Below ground uses

At just 1/10th the weight of gravel, Technopor foam glass is very lightweight, it is Fire resistent being in complicance with Euro class A1. Technopor is very stable and is load bearing with an exceptional compressive strength of approximately 500kN/m2.

The foam glass aggregate is around 30 - 50mm grain sizes and needs to be compacted by wacker plate if being used as flooring or foundations. You should allow up to 30% extra volume when calculating for a comapcted application. If used as a loose lay in a loft or under a suspended floor, then no compaction is required.

Renovation: Stone (Rubble & Dressed Stone), Brick, Cob, Wichert, Clunch & Strawbale
New Build: Stone, Brick & Block

Advantages:

• Cost effective compared to hemp or traditional lime mortars
• Easy to apply, coats up to 40mm overall in a day
• Ready to top coat in a matter of days
• Good vapour permeability

The ecoCORK plastering system

Secil ecoCORK is suitable for internal or external plastering. It is applied on top of a specially formulated consolidating mortar, which is hand harled onto the wall to get a key.

After the consolidating mortar one or two coats of ecoCORK can be applied in thicknesses of 10-20mm per coat, giving up to 40mm thick plaster or render in total. The surface is floated after a few hours to prepare for the finishing coat. After letting the ecoCORK harden for a few days, a final coat of Secil finishing mortar is applied. This can be done in a single coat of approx. 3mm thick.

Whilst we recommend using the Secil finishing mortar externally as it offers maximum compatibility and protection, internally the ecoCORK can be plastered with a wide range of materials including lime putty plasters and clay plasters. It can even be left as the finished surface and just painted.

Secil Consolidation Mortar For technical sheet click here
Coverage - a 25kg bag will make up 16 litres of mortar when mixed with water to a suitable consistency for hand harling. This gives a coverage of 5.3m2 at an average thickness of 3mm

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.

These are primarily used to tie cob block repairs in to mass cob walls. We would normally use 450mm lengths with half being hammered into the mass cob and the other half being laid. The longer lengths are generally used for repairing cracks. Headed Skew fasteners can be used for brackets etc. into cob without using timber dowels first.

Oak Lintels
We stock a wide range of 'green' and older stock 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.

Width(inches) x height(inches) x length(feet) divided by 144 x cost/cu ft gives you the cost of your lintel.

Example to work out the cost: 6" x 4"= 24 x ft= 192 divide by 144 = 1.33cu ft x £38 = £50.67 plus VAT

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. Lath prices are based on orders combined with our lime products. 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 lath prices are based on customers using our lime products.
