Whether it’s an office, warehouse or residential building, the elements and time can leave the exteriors feeling as though they need a facelift. Read on to find out how to prepare and paint your masonry and give it a new look.
Step One: Clean Down
In order to achieve the best results, the surface to be painted should be washed and cleaned down thoroughly. Begin by scraping away any dirt you can, then continue to clean using a cleaning and degreasing solution. Dilute the cleaning solution as instructed and clean with a brush, sponge, cloth or broom. This will aid you in removing any stubborn substances such as grease, oil, proteins and dirt, helping you to receive a smoother finish and better bond when it comes to painting.
Often masonry attracts moss which can age the building quickly. If needed, use a moss killing solution to remove anything stubborn. Brush the solution onto the surface, allow it to dry and dust off in two to three days. This will make the removal of any moss quick and easy.
Step Two: Primer
Once the surface to be painted is clean, prime the surface to improve the longevity of the paint and protect the building. Choose your primer based on the surface. For example, for an all purpose primer try this one. Though if you need something colourless that is effective at penetrating porous, mineral surfaces, you’ll want to use Mathys Pegafix. Finally, if you need to stabilise loose particles, in order to make it easier to apply a topcoat, again you need a specific product such as Mathys Fixonal.
Step Three: Defects
This step is optional, but if you inspect your walls and notice any defects such as cracks that need filling, this is the stage to repair them. A filling that forms a rubber-like mass that’s waterproof and resistant to ageing. If required, you can use a reinforcement fleece for more durability and active cracks when you come to coat the surface.
Step Four: Finish
In order to complete the facelift, a topcoat will be needed. You could use a waterproofing coating, to help protect your masonry, and stop rain from entering your walls. A coating like this will allow the surface to breathe whilst protecting it from water damage and remaining elastic so it does not crack or blister. If you’re painting sound masonry work, use a renovation paint to brighten it up. Even if the building is fairly new, the original paint may not have been as effective as it should be. If you’d simply like a clean, textured finish, then a protective paint with a quartz structure will do the trick.
Whichever paint you choose, remember to allow for two coats. Then you’ll be able to admire your newly made-over building!
