Yellowing film issue

Yellowing or oil-based yellowing is a problem where white or clear varnish film changes from its original color to yellow over time. This naturally occurs with common oil-based paints that primarily contain alkyd or oil.

Causes of Yellowing Film

• Chemical changes in alkyd oil paint or varnish oil
• The film is exposed to heat from ovens, water heaters, and heating pipes
• The film is in a dark place, such as behind pictures, furniture, or items inside a wardrobe, etc.

Solutions for Yellowing Film

• If the surface is in good condition or coated with glossy paint, prepare to lightly sand it with fine sandpaper, then clean it thoroughly.
• Repaint with high-quality acrylic paint from BEGER instead of oil paint, applying 1-2 coats as appropriate. For example, use Beger ColorShield water-based wood paint, Beger B-4000 special durable polyurethane paint with a 2-component system, or BegerShield Griptech 2in1 Rustproof glossy coating formula that requires no primer.
