Roofs of different conditions require different levels of care when it comes to painting. This article aims to give you instructions on what steps will work best for most roofs depending on their condition. Some surfaces will require all the steps while others can do with only some of the steps numbered below.
Roofing tiles that have been worn down by the elements should be repainted if they do not need to be replaced. “Chalking”, when there is paint dust left on your fingers when you rub your fingers on the painted surface, is a good indication that the new layer of paint is necessary. Removing all loose and flaking paint should be done before giving the surface a thorough cleaning.
1. Inspect the Condition of the Roof Well
If you notice the above mentioned “chalking” it is time to give the roof some much needed TLC. Now is when you should check for areas with peeling and lifting paint as well as any broken or missing roof tiles. Repair and replace any roof tiles before moving on to the next step in the process of painting your roof.
2. Clean and Sterilize the Roof
The first step in this process is to clean the roof you intend to paint well. A broom and water tend to work best for this job. Using Paintcor’s Ushevu as an overnight biocidal wash is a great way to ensure that the growth of bacteria, yeasts, fungi or algae do not later become a problem, especially in humid climates.
3. Apply a Sealant
Roof tiles are porous and tend to absorb a lot of paint. To avoid this, Paintcor’s Acryseal should be used as the first layer on your roof – after it has been well washed. It can be applied with a regular roller or block brush. Once it has had sufficient time to dry the roof is ready for the next step.
4. Determine Which Paint is Best for the Job
Here is when you need to determine which product is best for the needs of your roof. Paintcor Ruvacryl is a high quality pure acrylic roof coating for both galvanized iron and cement roof tiles. Other paints are designed to adhere to multiple surfaces, such as old enamel (once it has been sanded), clean glass, primed metal, plaster and old emulsion paint, particularly well.
5. Apply the Paint of Your Choosing
After some advice from your paint manufacturers choose the most appropriate paint for the task and get painting. Generally speaking, airless spraying is the quickest and easiest way to properly apply all the necessary layers of paint to a roof. You could also use a roller but in both cases, you should have a paintbrush handy to ensure the paint reaches all the corners, ridges and gaps.
