Building Chemicals

Choosing the Right Building Chemicals for Your Project

At County Building Supplies, our branch teams help builders, tradespeople and DIY customers choose the right building chemicals for a wide range of jobs. From improving mortar mixes and levelling floors to waterproofing, cleaning and finishing paving, choosing the correct product for the application can make a real difference to the quality and durability of the finished job.

Which Building Chemical Do I Need?

One of the most common questions our teams receive is which product is right for a particular job. Building chemicals cover a wide range of applications, so the best choice depends on the materials you're working with and what you need the product to do.

• Cement plasticisers and dyes can be added to mortar mixes to improve workability or achieve a particular mortar colour.
• Cleaning chemicals are designed for specific cleaning and preparation jobs, including removing dirt, staining or residues from suitable building and landscaping materials.
• Jointing compounds provide a practical way to finish joints between paving slabs and are available for different types of paving and installation.
• Screeding and floor levelling products help create a smooth, level surface before installing flooring and other finishes.
• Waterproofing products are designed to help protect suitable surfaces and structures against water penetration and moisture.

Because different products are formulated for different surfaces and applications, always check the manufacturer's instructions before use. If you're unsure, our experienced branch teams can help you find the most suitable product for your project.

Cement Plasticisers & Mortar Additives

Plasticisers are commonly added to mortar to improve workability and make the mix easier to use. Mortar dyes can also be used where a particular colour or finish is required, which can be especially useful when matching existing brickwork or achieving a consistent finish on new masonry.

The correct dosage is important when using additives, so always follow the manufacturer's mixing instructions rather than adding more product than recommended.

Jointing Compounds for Paving

Choosing the right jointing compound is an important part of completing a paving project. Different products may be suitable for natural stone, concrete or porcelain paving and can have specific requirements for joint width, depth and installation conditions.

If you're laying a new patio or replacing existing joints, our team can help you choose a jointing product that's suitable for the paving you're working with.

Floor Levelling & Screeding

Floor levelling compounds are designed to help create a smooth and even surface before the final floor covering is installed. The correct product will depend on factors such as the existing substrate, required depth and whether the application is internal or external.

Good surface preparation is essential, so make sure the substrate is prepared in accordance with the manufacturer's instructions before applying a levelling or screeding product.

Waterproofing & Protection

Waterproofing products can be used in a variety of building applications where protection against moisture or water penetration is required. The right solution will depend on the surface, location and level of exposure, so it's important to use a product specifically designed for the application.
