Lime Plaster Filler 1 L

Conservation Filler is designed for home owners to fill cracks and stop gaps.

The problem with modern fillers which, some say, are easy to work and even though we can sand and plane them�to get�a�perfectly smooth repair.�we will not stop the mend being seed in certain lights. This is because the resin filler reflects light through the paint at a different wave length to the plaster around and below. So at certain angles it can be seen. �

Not so with Conservation Filler. The filler is made of completely natural lime and earth materials and is essentially the same material as the original plaster. It is both compatible with your building and is perfect for anyone who has fine cracks which need filling.��

It deals with zero to 2mm wide cracks it deals with well, 5mm cracks may have to be completed with two applications.

Pre-mixed Lime Plaster

Benefits

Lime putty plasters have great benefits from using cement & gypsum plasters.

Reduced condensation problems,� Allows wall(s) to "breathe",� They can handle structural movement better,� Self-healing properties reduce cracking problems.

Preparation

Ensure that the background is cleaned thoroughly; this can be done using a stiff brush. Any loose plaster should be removed with hand tools only. All plaster that has sound adhesion to the structure should be left on. If the background is saturated check for external cracks, damaged water systems and missing pointing. These problems must be cured before any plastering is undertaken. Any internal gaps or voids should be filled with lime putty pointing mortar, packing joints deeper or wider than 15mm with packing material. (see pointing motar notes)

Suction control

The day before plastering is to be undertaken the surfaces should be sprayed with clean water, the amount of water depends on the prosity of the stone e.g. sandstone & brick require more than flint stone. If necessary several sprayings may be needed, with the last damping just before application of plaster.

Pre-mixed

All lime mortars and plasters benefit from being pre-mixed for a minimum of a couple of weeks and then "knock-up" again prior to use to plasticize them - this reduces shrinkage in the plaster.

Dub - out

On stone surfaces you will have to prepare the surfaces for plastering. If you place a straight edge vertically on the wall, you will need to fill the gap between the straight edge and the wall. This is done by using a gauging trowel and haired lime plaster, only 10 - 12mm must be applied at any one time, so 2 - 3 coats may be needed. These coats should be scratched to bring out the hair, this allows bond with the next coat.

Base coat(s)

This coat(s) must be applied no sooner than 3 days after the Dub coat. Normally coat thickness is around 12mm; it must not be applied over 15mm thick. Once the coat has slightly hardened, the coat should then be rubbed with a dry bag to bring hair to the surface, this gives the next coat a good keying surface, then it should be scratched with a scratch comb in a diamond pattern.

Float Coat

This is a matured unhaired mix of one part lime putty to one part fine silica sand. again once the surface has slightly hardened, using a damp sponge lightly go over the plaster. This provides a good key for the lime-wash, and also helps with carbonation.

Plastering on Wooden Laths

Laths should be dampened before plastering starts.� Apply a first scratch coat of 3/1 haired lime mortar through the lath, leaving around 8mm on top of the lath. Do not over trowel this coat, use a dry paper bag rubbed lightly over the surface, this brings hair to the surface giving a good key for the next coat. then lightly scratch the coat with a scratch comb.� Apply float coat of 3/1 lime finishing plaster, if any shrinkage cracks appear, lightly spray the plaster with water and trowel or sponge in the cracks.
