Texture is a Limitless Finish
Lime plaster has been used as a material for building and finishing various surfaces since thousands of years. Lime plaster applications are incredibly durable and flexible. Finishes achieved with lime plaster can be applied on a variety of surfaces and structures. It is equally suitable for interior and exterior applications. You can use it on stones, bricks, stairs, walls, ceilings as well as exterior facades. For exterior facades, lime plaster is very suitable as it is breathable and withstands water without sustaining any damage whatsoever.
A variety of techniques are used to achieve different types of finishes when using lime plaster. Here is a look at textured finished for lime plaster and the techniques used to create these finishes.
Rough Cast Finish
This type of finish, as the name suggests, has a rough and spattered look. In creating this finish, mortar is applied to a surface by dashing it with a trowel. A wooden float is then used to level the surface, although not making it quite smooth but retaining its overall roughness. Such a textured plaster finish is typically suitable for exterior surfaces.
This type of textured finish has a sand-like texture and outlook. To create this finish, lime plaster is first applied in zigzag lines. On top of this coat, a second coat is then applied and smoothed. Fine sand is then applied on this second coat with a wooden float. The end result is a finish with a uniform sand-faced texture outlook.
In this type of lime plaster texture, an extra thick layer of plaster is applied to a surface. A steel blade is then used to scrap the top layer. The end result is a highly textured, scrapped finish that is better able to resist cracks. Such a textured finish is best suitable for surfaces which may see a lot of exposure to human interaction.
A pebble finish is when small pieces of pebble are dashed on to the top layer of the plaster after it has been applied. A float is used to slightly press the pebbles so that they become firmly affixed to the plaster. Colourful pebbles give the plaster a very unique aesthetic appearance.
Benefits of Using Lime Plaster
Lime plaster offers a vast range of benefits for which it is often preferred as a finish for walls and other surfaces. Here are some of the key benefits:
- Lime plaster is very well resistant to water exposure. This makes it a great choice for exterior surfaces as well. Lime plaster absorbs water and then lets it evaporate without sustaining any damage to its structural integrity.
Lime plaster requires no expansion joints. This is because it is more solid and fixed, not likely to become cracked or damaged over time.
Lime plaster has a non-neutral PH. This makes it highly resistant to mould and an overall healthy material for use in construction.
Lime plaster is incredibly flexible to use so that a variety of textures and finishes are possible with it.
