Product categories

Adhesives & glues

Strong, lasting bonds for timber, metal, ceramic, concrete, and more. Whether you need a fast-set solution for a tough repair or a heavy-duty structural adhesive for a demanding build, there's a proven product for the job.

Popular applications:

  • Bonding dissimilar materials
  • Structural repairs and assembly
  • Flooring and tile installation
  • Craft and general-purpose bonding

Sealants & caulks

Seal gaps, joints, and penetrations with confidence. High-performance sealants deliver weatherproof, flexible finishes that hold up against movement, moisture, and temperature change, indoors and out.

Popular applications:

  • Wet area and bathroom sealing
  • Window and door frames
  • Expansion joints and movement gaps
  • External weatherproofing

Fillers & patching compounds

Achieve smooth, professional surfaces before painting or finishing. From hairline cracks to deep holes, the right filler makes the difference between a patch job and a clean result.

Popular applications:

  • Wall and ceiling repairs
  • Timber and surface preparation
  • Exterior crack filling
  • Pre-paint surface finishing

Surface preparation

A great finish starts with proper preparation. Surface prep products, including cleaners, primers, and strippers, ensure adhesion, coverage, and lasting results on every project.

Popular applications:

  • Pre-paint cleaning and degreasing
  • Priming porous or problem surfaces
  • Paint and coating removal
  • Surface restoration

Choosing the right product

Not sure where to start? Here's how to narrow it down:

  1. Identify your surface. Timber, concrete, glass, and metal each have specific requirements, so the material you're working with should drive your product choice.
  2. Consider the environment. Will the product be exposed to moisture, UV, heat, or movement? Match the product to the conditions it'll actually face.
  3. Think about finish. Is the result visible? Choose products that deliver clean, paintable, or colour-matched finishes where appearance matters.
  4. Check cure and dry times. Some jobs need a fast-set product; others benefit from extended working time. Know your timeline before you start.

Why product quality matters

In hardware and building supplies, quality isn't a luxury, it's a necessity. Inferior products mean rework, callbacks, and wasted time. High-quality products deliver:

  • Stronger bonds and seals that last for years, not weeks
  • Consistent performance across temperature ranges and conditions
  • Clean, professional finishes that hold up over time
  • Reliable results, job after job

When the job has to be right, there's no room for products that fall short.

Tips for best results

Getting the most out of any adhesive, sealant, or filler comes down to preparation and technique:

  • Clean the surface thoroughly before applying any product. Dust, grease, and moisture are the enemies of adhesion.
  • Follow application instructions. Temperature ranges, mixing ratios, and open times exist for a reason.
  • Apply in the right conditions. Avoid extreme cold, heat, or humidity unless the product is specifically rated for it.
  • Don't rush the cure. Allow full cure time before loading, painting over, or exposing to water.
  • Use the right tool. A quality caulking gun, spreader, or applicator makes a real difference to the finish.

Frequently asked questions

What's the difference between a sealant and an adhesive? Sealants fill gaps and block the passage of air, water, or sound. They stay flexible after cure. Adhesives bond surfaces together and typically cure rigid or semi-rigid. Some products, like adhesive sealants, are engineered to do both.

Can I paint over sealants and fillers? Most fillers are paintable once fully cured. Sealants vary, so check the product label to confirm paintability before you start. Using a non-paintable sealant in a visible area is a common mistake that's easy to avoid.

How long do adhesives and sealants last once opened? Shelf life varies by product. Most sealants and adhesives last 12–24 months when stored correctly, sealed, at room temperature, away from direct sunlight. Always check the use-by date before starting a job.

What should I do if a product doesn't bond properly? Surface preparation is the most common cause of bond failure. Make sure surfaces are clean, dry, and free of contaminants, and check that the product is rated for both the surfaces and conditions involved. If the issue persists, refer to the product's technical data sheet or contact the manufacturer.
