8 Steps that Painters Follow to Prevent Peeling Exterior Paint

by Eva Spenser Innovation

Households, as well as business stakeholders, are quite often than not, intrigued by the premature peeling off of external paints. Now, this can be arrested by following a few steps that the experienced paints would take while painting the external walls. When it comes to taking care of external walls that have paints peeling off, they take a few steps that help them to make amends. 

Here on this page, let us discuss a few steps, which the professional painters follow while taking care of the peeling off paints from the external walls! 

Identifying the underlying cause….

Well, it is fairly easy to paint an area of an external wall with peeled-off paint. However, that will not help the cause and the new paint will meet with the same fate after a few days if the root cause of the problem is not identified and taken care of. There are multiple reasons behind peeling off paints. 

They may include poor construction of the wall, accumulation of moisture within the walls, improper rolling methods followed, painting in weather conditions that are not conducive poor adhesion due to poor quality of paints used, incompatibility between the paints used and the primer, and of course the normal depreciation of external paints. To start with, the professionals will identify the precise cause behind the issue. 

Removing the cracked, blistered and peeling paint…

Before anything else, they at first scrape off the loose paint with the help of a scraper. Then they use wire brushes for sweeping away the remaining debris and follow it up by smoothing the surface with the help of fine-grit sandpaper.

Applying fillers…

Then they would apply fillers to fill up and repair the cracks and holes on the wall and leave the wall like that, allowing the material to dry up properly. Then, an exterior painter in Keilor East would use the same sandpaper for eliminating the irregularities and roughness, thereby making the area even and smooth. To prevent the recurrence of peeling, they would wash the wall and then let the water dry out completely before they apply primer at first and then, the paint. 

Using a pre-painting cleaner…

Now, they will use specialised cleaning solutions for preparing the wall for fresh painting. Quality products from good companies come up with better adhesion properties that encourage a better cohesion between the paint and the substrate. It will improve the 'recoatability’ of the previously painted surfaces, and terminate the mould spores, which negates the future growth of mould. 

Checking the weather…

Next, the pros will check the weather. In most of the cases, the paint on the external walls peels off due to painting under the harsh Victoria sun in the height of the summer. Ideally, exterior paint needs to be applied only and only when the surfaces are dry, and under shade or during the early morning or late afternoon, when the relative humidity level and the temperature hovers between a low to moderate level. 

Choosing the right paint and primer…

Since Victoria has a subtropical climate, the painters in Keilor East like any other suburbs around Melbourne would opt for waterproofing products that can help to prevent moisture-related problems, which normally lead to the peeling of exterior paints. 

Correcting the blisters…

In some cases, the exterior paints peel off due to the emergence of blisters, which may appear overnight or in a gradual process following the painting. When that happens, and the clients hire these pros, they wait till the paint dries (in cases when the blisters appear overnight immediately after the painting). Then they would cut open the blisters and remove the loose paint. If the plaster or the stucco is visible after the removal of the paint, it was the result of moisture trapped inside. If the previous paint coat is visible, it is the result of the application of the topcoat before the undercoat had thoroughly dried up. 

Surface Retexturing..

This is the last step, wherein the pros will do the retexturing of the surface in such a way that the finish marches with the existing surface.
