Bantaskin External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for Bantaskin, backed by a 12-month guarantee. Ask us for a quote.
- Failed sealant between panels on a façade
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
Keeping the joints in good condition
Looking after new joints is easy:
- Walk round the building once a year and look at the joints
- Never let anyone fill a movement joint with mortar
- Keep soil, plants and ivy away from the joints
- Get split or bare joints resealed while the damage is small
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
External mastic in Bantaskin
For buildings in Bantaskin, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you have panel joints letting water in and plants rooting in failed movement joints, we can put it right.
Outside joints can only be sealed when they’re dry, so work in Bantaskin depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
Each job carries a 12-month guarantee, whatever its size.

Why act early in Bantaskin
Sealing over the top of old mastic does not hold for long. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.

Quotes for external mastic in Bantaskin
Every job gets its own quote. These are the things that affect it:
- Working hours on commercial sites
- The old material and how stubborn it is
- Access and height
- The number of rooms or windows
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Asking for a quote
When you call or email, it’s useful to know:
- Photos by email, if that’s easy
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
Every job is quoted individually, so start by telling us what you need. Simply drop us a line at info@mrmastic.co.uk and describe the job, and pictures are welcome.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on how much there is to do. For a place like Bantaskin, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

How long does external mastic take?
It depends on the size of the job, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We’ll tell you when we quote.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can a movement joint be filled with mortar?
No. Cement or mortar cannot stretch, so the joint stops doing its job. If it has already been filled, we can generally cut it out and reseal it.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Surface by surface
Cladding and façade panels
If the façade has a specified sealant, that’s what we use. Tell us what the building has when you get in touch.
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap so the sealant isn’t too deep.
