Our Pre-treatments and Primers collection is designed to deliver superior adhesion and long-lasting performance for sealants, adhesives, and joint systems. Whether you’re tackling porous substrates like concrete and wood or preparing metal and smooth surfaces, applying the right primer or pre-treatment dramatically improves bond strength and joint durability. This category features a range of professional-grade products that prepare the surface, remove contamination, and ensure optimal sealant and adhesive performance on the first application.
Pre-treatments and primers are specialist solutions applied before sealants or adhesives to prepare surfaces for better bonding. They help remove oil, grease, dust and other contaminants, and in many cases form a micro-adhesion layer that enhances the mechanical grip of the sealant. Some products also act as activators or cleaners, improving performance on both porous and non-porous substrates.
When sealants or adhesives are applied to inadequately prepared surfaces, poor adhesion, early joint failure and sealing losses are much more likely. Primers and pre-treatments:
Using the right primer ensures that your sealant or adhesive performs to specification and maintains integrity under stress, weather, or movement.
Our Pre-treatments and Primers range includes industry-trusted solutions such as:
These products are carefully chosen to match the rigorous performance expectations of construction professionals, tradespeople, and DIY enthusiasts alike.
Selecting the correct primer depends on several factors:
Make sure to follow manufacturer guidelines and test compatibility where necessary to achieve the best results.
Cleaners remove surface contaminants like grease and dust, while primers create a chemical or mechanical bridge that improves adhesion between the sealant and the substrate.
Not always. Some high-performance sealants can bond without a primer, but many professional applications, especially on non-porous or difficult surfaces, benefit significantly from using one.
Yes. Proper priming enhances adhesion and reduces the risk of sealant failure due to movement, weathering, or substrate contamination.
Drying times vary between products, but most solvent-based primers require a short flash-off time (often minutes) before applying the sealant. Always check product instructions.
Yes. While some primers are geared toward professional installation, many are user-friendly and suitable for experienced DIYers when used according to manufacturer guidelines.
