Adhesives and Sealants for Every Job
Suitable for interior and exterior applications, our products are designed to grip, flex and hold so a joint stays sealed for years. The range is built around the jobs that come up most, whether you're a homeowner, a landlord keeping on top of a property or a tradesperson on site: sealing roof leaks and flashings, filling gaps around frames before decorating, bonding to brick and stone, and anchoring fixings into masonry. Everything is made to take real-world movement and weather, indoors and out.
What's in the Range
- Need to repair lead flashing? Lead Roof and Flashing Sealant is a lead mastic that bonds lead to concrete, brick and stonework, and stays elastic on joints that move. Moisture curing, and made for repairing lead flashings, roof joints and leaks, which is one of the most common causes of a damp patch indoors.
- Decorating after filling gaps? Decorator Caulk/Filler is a fast-curing, general-purpose filler and sealer with good adhesion to most building materials. Ideal for sealing gaps around door and window frames before painting, and it can be overpainted or papered over for a tidy finish.
- Parabond 600 White and Parabond Transparent are fast-curing, flexible sealants with strong adhesion and no primer needed. A dependable choice for sealing and bonding jobs around the building, inside and out.
- Fixing heavy brackets into masonry? Parachim Polyester Set Resin Anchor is a two-part resin anchoring system for setting bolts, studs and plates into brick, masonry, stonework and concrete. The product to reach for when you are fixing a gate post, a handrail or a bracket into solid masonry and need it to stay put.
- Sealant Gun and Polyester Set Resin Gun are the applicator tools that lay the cartridges down cleanly and save you fighting the job.
Sealing or Bonding: Which Do You Need
It's worth knowing the difference, because it points you straight to the right product. A sealant fills and closes a gap or joint to keep water and air out, and stays flexible so it can cope with movement as materials expand and contract. An adhesive bonds two surfaces together and holds them in place.
Some products do both. The hybrid sealants seal and grip at the same time, which is why they work without a separate primer. So if you're sealing frames or roof joints you want a flexible sealant, and if you're fixing studs or plates into masonry you want the resin anchor.
Built for Exterior and Interior Applications
Roof and masonry work has to survive everything the weather throws at it, so these products are made for water resistance and movement, not just a tidy line. The same range handles interior jobs like caulking around frames before painting. The trick is matching the product to the surface and to how exposed it will be, and that's where it pays to ask. If you're weighing up two options, contact our team for free technical advice and we'll point you the right way before you buy.

Frequently Asked Questions
What's the difference between a sealant and an adhesive?
A sealant closes a gap or joint to keep water and air out and stays flexible to take movement. An adhesive bonds two surfaces together and holds them. Hybrid sealants do a bit of both, sealing and gripping at once.
Which product should I use on lead flashing?
The Lead Roof and Flashing Sealant. It's a lead mastic made to bond lead to concrete, brick and stonework, and it stays elastic on joints that move as the flashing heats and cools through the day.
Do I need a primer?
Not for the Parabond hybrid sealants, which are made to adhere without one. For anything else, check the individual product page or technical data sheet for surface prep before you start.
How good is the water resistance on these sealants?
Strong, which is the point of most of the range. The Lead Roof and Flashing Sealant waterproofs instantly to seal leaks in most types of roofing, including flat roofs, slates, roofing felt and gutters. The Parabond sealants create a watertight or airtight seal for jobs indoors and out. As with any sealant, water resistance comes down to a clean, sound surface and a properly smoothed joint, so prep the area first and let the product cure fully before it gets wet.
Which products are suitable for exterior applications?
Most of the range. The lead flashing sealant and the Parabond sealants are made for exterior applications and stand up to weather and movement on roofs, frames and masonry.
The polyester resin anchor sets fixings into outdoor brick, stone and concrete.
The decorator caulk is better kept to interior frames, since it's a general-purpose filler rather than a weatherproof sealant. If a job sits somewhere in between, check the product page or ask our team before you commit.
Choosing the right sealant can feel confusing, especially when products look similar. If you're unsure, our technical team is happy to point you towards the right solution.
