Limestone Sealing for Buildings and Landscaping
Limestone is a popular building material because of its availability and beautiful appearance. In the Perth area, it’s widely used in landscaping and building, particularly for decorative and retaining walls. Panther Protective Coatings offer limestone sealing to maintain the appearance limestone walls.
Natural limestone is cut from quarries in blocks and used in feature and retaining walls. The natural stone is highly porous with a high calcium content, and prone to absorbing moisture. The rough surface texture easily accumulates grit, dirt and other environmental elements. This can encourage the growth of mould, moss and bacteria which can affect the appearance and integrity of the walls. Reconstituted limestone is made from crushed natural limestone which is mixed with cement and then moulded into building blocks. It is less porous than natural limestone but still has a high calcium content and textured surface that holds on to dirt and encourages surface growth.

How Limestone Wall Sealing works
An impregnating sealant provides the most effective protection against discolouration and structural damage to your limestone walls. The sealant is applied to the wall’s surface and is absorbed into the porous limestone, filling in the tiny holes and fissures. Limestone sealing stops moisture from being absorbed into the rock, but still allows any internal moisture to evaporate. Protective limestone sealant helps your walls resist stains as well as stopping moss and mould from growing. It is the best way to protect your investment and keep your walls and exteriors looking great.
