MacAndrews are an Exterior Wall Coatings specialists and we approach your property in a professional manner. Our team will explain everything they are doing step by step, keeping you updated throughout the process.
OUR EXTERIOR WALL COATINGS PROCESS
Step 1: Our installers will wash down the building to remove all moss and algae which was formed on the building over the years, followed by an anti-fungal wash to prevent dirt and grime reforming on your property.
Step 2: We then check all roughcast and brickwork for repairs. An example is brickwork needing pointed or roughcast repairs. This helps make the building water tight and crack free for the coating to be applied at a later date. All repairs will be done to a high standard by our experienced installers and will be complete weather permitting. Repairs have to be done on a dry day to make sure they cure on the outside and on the inside of your property.
Step 3: We then proceed to the final stage by applying two coats of our rubberised, water repellent coating. All windows will be masked and all ground will be sheeted by our installers before applying the coating. This helps protect all other areas of your property to give your house an outstanding finish making it look as good as new.
We make sure our customers are 100℅ satisfied.

MACANDREWS RENOVATIONS USES LONG LASTING EXTERIOR WALL COATING PAINT THAT PROTECTS AND INSULATES
If you are looking for an exterior wall coating that will last for a long time, then look no further. We use a water-based wall coating that is eco-friendly. Not only will you be giving your home a new paint job, but you will also ensure that the paint you are using is not harming the environment in any way. Not only that, it provides a lot of benefits to you and your home.
The wall coating contains ceramic spheres that help in reducing the energy consumption of your home. By simply applying it to the walls, it improves its insulating properties. The wall coating is flexible and hard wearing; you don’t need to worry about repainting your home in the near future.
It is elastic, which makes it waterproof and water vapour permeable. Water vapour permeability is important because there will come a time when the interior wall will get wet. The wall coating will allow water to escape as water vapour.
MacAndrews can also paint of other external surfaces that include concrete, asbestos, cement, or brickwork. It can also be used on suitably primed iron work, aluminium, and surfaces that have been painted with oil paints or emulsions.

No the only way the coating will do this is if the building is not washed properly. Or the coating isnt applied properly. Ie curing time or walls have been wet.
What is the average drying time?
Drying is dependent on how fast water evaporates from the paint. At 20°C and relative humidity of 50 percent; it takes 45 minutes to touch, around eight hours to handle, 24 hours to apply another coat, and around two days for full hardness. The wall coating requires at least 5°C and 80 percent relative humidity to it to dry. During cold weather, the wall must be free of retained frost. It is also important to make sure that the wall is dry before applying the paint. Wipe the exterior wall dry first before the application of the coating.
How to prepare the wall before applying the Exterior Wall Coatings?
There are several things that you need to consider first before applying the exterior wall coatings. First of all, the wall must be free of wetness. Wet or damp walls should not be coated. It is important to repair any structural faults that lead to the build-up of moisture that includes broken guttering or rainwater downspouts.
Fungal or algal deposits must be removed before applying the wall coating. This can be done by power washing the surface, and then coated with a special antifungal solution.
For newly rendered or loose surfaces, it is important to make sure that they are free from dirt, oil, chalk, dust, grease, and any other friable materials. If you are dealing with extremely loose surfaces, then you should first coat it with a stabilising primer first.
Hairline cracks can be covered by the paint we use. But substantial cracks must first be filled with sealant first before applying the wall coating.
How we apply the wall coating?
MacAndrews use rollers, spray and brushes. The coverage is determined by the temperature, application method, and the type of substrate. If the surface is rough, we use a heavy pile roller. If the surface is smooth, then we use a short to a medium pile of up to 12 inches.
If we are going to use the spray, we use one that is airless. It is recommended to use a tip size of 18 to 23 thou, and pressure between 150 and 200 bars. Before applying the wall coating, we make sure that we mask the areas that should not be coated.
What areas of Scotland do you cover?
We cover all areas throughout the Central Belt of Scotland, including Tayside, Highland, Fife, Strathclyde, Lothian & Borders, South Lanarkshire, North Lanarkshire, Edinburgh, Perthshire, Dumfries and Galloway, Scottish Borders, and Argyle & Bute.
