Laths & Lime Plasters
Laths are used on timber framed, studwork and on structures of uneven surfaces to bring them into a oneness ready for the application of lime plaster. Laths are either riven (split) or sawn. Riven laths are stronger than sawn but because they are split by hand, they are a lot more expensive, therefore people tend to use sawn. Laths tend to be between 25-32mm in width and 6-8mm thick. You can purchase laths in soft and hardwood. When applying the plaster to the laths it has to be moist enough so that you can push the plaster through the gaps, to create the perfect key.
Laths are fixed parallel to each other, but need to be staggered every 8-10 laths so there is no shearing point, laths should be fixed between 6-8mm apart. Fixings can be stainless steel ring shank nails, coated screws or galvanised staples. However you should always take into account that the fixings are not only holding up the lath, but also the plaster that is applied to the lath. Caution must be taken when hammering nails in because this can cause a shockwave which could do potential damage elsewhere in the building. When covering beams or a flat surface with laths you will need to counter lath to leave a gap for the plaster to wrap around the lath to give a mechanical key.
Lime Plaster
Lime plaster is one of the ancient materials, existing thousands of years ago. It was used in construction for hundreds of years. A mixture of lime putty, sand, and water gives a highly breathable and flexible plaster, ideally suited for use on traditional and historic buildings. Lime plaster accommodates a small amount of movement in moisture that can occur within a building, thus preventing damp and decay in some older structures, where good moisture control is required. We are committed to being the best manufacturers of quality lime plaster with the use of traditional methods, making sure it answers the needs of restoration projects and the sustainment of the original structure. Lime plaster has been applied to preserve an aesthetic quality, yielding to the user a very natural look with a finish that is matte and matures over time.
The porous nature of the plaster allows it to absorb and release moisture, resulting in a building which not only promotes health but also contributes to the comfort of the living environment. Limebase makes its lime plasters carefully, aiming to create quality and durable products, sympathetic to the historical context of buildings. Whether one seeks an internal or external lime plaster, no other will be best for those seeking a sustainable finish and authenticity. In our devotion to making products restoring and retaining character and longevity in heritage properties.
