External mastic in An t-Aodann Ban: local notes
An t-Aodann Ban is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
Whether the job is in An t-Aodann Ban itself or nearby, the right material for each joint matters as much as a neat finish.
An t-Aodann Ban (Gaelic: Edinbane) is in Highland. Every kind of property in An t-Aodann Ban is covered for external mastic. Every job comes with our one-year guarantee. Our area takes in 253 places across Highland, large and small.

How we handle external mastic in An t-Aodann Ban
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. If you have water getting into walls through failed joints and sealant pulling away from one side of the joint, we can help, whatever the surface.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
All of our work is guaranteed for twelve months.

FAQs for An t-Aodann Ban
Do you cover smaller places like An t-Aodann Ban?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Is An t-Aodann Ban in your area for external mastic?
Yes. We work across all of Scotland, and An t-Aodann Ban is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear quote.
Is the work guaranteed?
Yes. All our work carries our 12-month guarantee.
How long will you be here?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
How long does external mastic last?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Pointing it stops it working and can lead to cracking. We’ll reseal it with a flexible sealant.
How it works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the building. Somewhere like An t-Aodann Ban may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First, the joints are inspected and the access agreed.
- 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.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Clear the area around the work
- Mention if the joints have been sealed before
- Keep children and pets away from the work area

What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Subsidence or other structural problems
- Cracked brickwork or render that needs a builder or plasterer
- Adding movement joints to masonry that has none
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.
Where we work in An t-Aodann Ban
- Copings & trims
- Render & cladding joints
- Joints between brick and frames
- Façade panels
- Concrete & block
- Brickwork movement joints
Why deal with it now?
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Around An t-Aodann Ban, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Surface by surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Send us any details you have about the façade.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Clear growth from the base of walls and joints
- Keep movement joints as flexible joints, not mortar
- Walk round the building once a year and look at the joints
- Have failed joints looked at early
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

What we’re called out for in An t-Aodann Ban
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
If you can see any of these, it’s time to have the joints looked at:
- Leaking joints around cladding and façade panels
- Sealant that has lost its bond to the brick or render
- Old sealant gone brittle and cracked
- Plants rooting in failed movement joints
In and around An t-Aodann Ban, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
