How to Apply Bruhn Rockseal Sealant on Limestone
Limestone is defined as a sedimentary rock that composes largely of the mineral calcite and aragonite. It is also composed of grains made from skeletal fragments of marine organism such as coral and foraminifera.
Limestone is very common in architecture and widely used in the UK and America. Across the world, Landmarks such as the Great Pyramids of Egypt and its associate complexes are made of limestone. Tracing back the human history, limestone has been already used in building monuments, houses and other structures.
Today, limestone has been more popularly used in building houses and commercial establishments. Because of the growing demand of this material in the construction industry, many limestone manufacturers are producing limestone in various types and colours to suit consumers unique preference.
Though limestone is a natural stone, when used as a construction material it needs protection against other elements to retain its durability over the years. That is because it can easily absorb moisture which can cause discolouration and its dirty appearance.
To avoid this, a seal must be applied over the stone’s surface. One of the most trusted limestone seal today is the Bruhn Rockseal which aims to protect natural limestone by coating the stone’s surface and converting it from soft material to a hard wearing water repellent finish.
The Bruhn Rockseal coating penetrates deep into the pores of the limestone and strengthen it so that the treated surface will not dust thus highlighting the natural colour of the stone. The seal also prevent fungal growth and allow the stone to age naturally. The seal is also resistant to airborne pollutants, ultra-violet rays.
To apply the Bruhn Rockseal, follow the following procedures:
- The sealant is supplied in 205 litre drums and it must be stirred thoroughly before application.
- The limestone must be power washed with a low pressure fan spray to clean its pores before applying the sealant. Allow stone to touch dry before applying the sealant.
- The stone should not be washed or sealed until the mortar has hardened sufficiently.
- Ensure site is free from dust during washing and sealing.
- Sealant must be applied in one heavy coat only. Do not double coat as this causes run marks.
- Allow at least 24 hours for the sealant to dry. Allow two months for product to cure.
- Wash out hose lines with clean water after use.
