The issue of colored film cracking and flaking (Cracking/ Flaking)

Color film cracking and flaking is the separation of dried paint film, characterized by small cracks that eventually cause the paint film to lose adhesion to the surface and gradually flake off in sheets.

Causes of color film cracking and flaking

• Insufficient adhesion and flexibility of the paint
• Excessive thinning of the paint or not thinning the paint according to the ratio specified on the packaging
• Poor surface preparation, such as bare wood
• Environmental conditions with high temperatures, humidity, or strong winds causing the paint to dry too quickly
• Oil-based paint may become brittle when used for a long time on wooden surfaces and surfaces with cracks

Solutions for color film cracking and flaking

• Scrape off as much of the old paint as possible, sand the surface, and clean it free from paint film debris and dirt.
• Apply a primer with properties that enhance adhesion suitable for each type of surface, for example:

– New plaster walls should be coated with flexible primer BegerCool Insulating Primer #9000 or BegerCool UV Shield Primer #9900
– Old plaster walls should use multipurpose primer Beger Pro Quick Primer B-1900
– Real wood should be coated with Beger Wood Sealer B-2000

• Topcoat with high flexibility paint such as BegerCool Flex Shield mixed with no more than 5% water or other desired Beger acrylic paints, mixing water according to the instructions on the packaging before use, and allowing to dry between coats for at least 2-3 hours. Recommended acrylic paints include:

– Premium grade cool house paint BegerCool DiamondShield 15
– High adhesion cool house paint that protects against UV rays BegerCool UV Shield
– 2IN1 gloss paint BegerShield Griptech 2IN1 RustProof formula without thinner
