Paint failure is a common issue and it occurs on a large scale. Residential and Commercial Painting is not a permanent. Paint comes off of the walls eventually and it needs the renewal after a certain period of time. From priming the walls, to picking a finish, to choosing the right color, to choosing professional Painters in Perth there’s plenty of chances for error without the proper guidance.
Below you can find some of the more common painting problems, along with their probable causes and solutions.
Chalking
Paint Chalking is the formation of fine, white, chalky powder on the surface of the paint. It occurs due to weathering of paint. The paint binders slowly degrade due to moisture which results into easing the hold of the binder on paint pigments.
Be sure to clean and remove all the dirt in the area you intend to paint before you start. To remove existing chalking, start by scrubbing with a trisodium phosphate cleaning solution, then rinse with water. Afterwards, be sure to give the area ample time to dry and use high-quality latex paint to do the repainting.
Cracking
When the painting is done under hot weather conditions like in summer, the water-based paints dries too fast. The splitting of dry films through one coat leads failure of the complete painting.
First, remove the affected coating by scraping & sanding. Then apply primer as a base, and repaint. Using a good quality paint is the key here. Low-quality, oil-based ordinary paint tend to mud-crack more often. Quality acrylic paint has a high TSS (total suspended solids) content, and as a result will reduce the risk of mud cracking.
Peeling
Paint coating comes off easily before time due to poor adhesion. Poor Adhesion of paint coating results into peeling.
Simply, you’ve to remove all loose paints then repaint with a top quality paint.
Blistering
Blistering paint is identified by small to medium sized bubbles or blisters under the paint and is most common on wood siding and trim.
Simply avoid painting under the imperfect conditions; especially under the hot summer sun, or when it’s raining. However, if you’re already affected by blistering, you must be prepared to start from scratch. Though there are some alternatives, all of them require a great deal of effort, and often your best bet is to repaint the entire affected area.
Mildew
Mildew is a fungus feeding and growing on the paint and is identifiable by its grey, brown, green or dark black “splotchy” spots.
If you’re sure that mildew is the problem, use household bleach solutions to scrub the mildew from the surface. Rinse the area with clean water and wash it with detergent to get rid of the mildew. Using top quality acrylic paint will help to protect against mildew. Additionally, you can consider installing an exhaust fan in high moisture areas.
