Construction Chemicals
Construction chemicals are chemical formulations used with cement, concrete, or other materials at the time of construction, to be able to hold the structure materials together. Building chemicals are a crucial part of most projects and are useful for a wide range of applications. We offer a wide variety of building chemicals at Howarth, to ensure you can select the best building chemical for your projects.
PVA bond is a multi-purpose bonding agent, which can adhere to most well-known building materials where at least one surface is absorbent. It is extremely versatile, waterproof, and non-toxic and is suitable for a multitude of tasks and requirements.
Jointing compounds are a powder that is mixed with water to seal and repair joints in paving, stone, and brickwork. The application is very easy, taking as much as three coats, and when applied, the compound can efficiently seal all flaws from the surface.
Cleaning chemicals are a surface treatment used to remove anything that looks unsightly, such as ingrain dirt. They are a good product to use to ensure your building projects remain of a high-quality appearance.
Waterproofing is used to prevent water from embedding through the compound material, typically used on paving and mortars, which can massively reduce the risk of long-term damage.
