What is a Shower Door Frame?
Shower door frame, as the name suggests, is the frame that supports the glass shower door, usually made of aluminum, stainless steel, or plastic. Because the bathroom is a high humidity environment for a long time, water vapor erosion on the surface of the door frame is vulnerable to oxidation, rust or discoloration. Different materials of door frames are suitable for different types of paint, so it's important to find out what material your door frame is made of before you start painting.
Why use waterproof paint?
Ordinary paint is easy to peel off in a humid environment, and even becomes a sticky coating that cannot be firmly attached to the surface of the door frame. The waterproof paint is specially formulated to effectively resist water vapor, prevent the paint layer from falling off, moldy or yellow, and keep your door frame beautiful for a long time.
The importance of mildew resistant paint
The moisture in the bathroom not only affects the appearance of the door frame, but also can breed mold, especially in the corners and seams of the door frame. Mildew resistant paint contains antibacterial ingredients that can effectively reduce mold growth, making door frames easier to clean and bathrooms more hygienic.
Paint vs. spray paint, which is better?
If you want to control the thickness of the coating more finely and avoid spraying errors caused by spray spray atomization, painting is a better choice. Paint brush can go into the detail of the door frame to ensure even coverage. If you want to finish painting faster, spray paint can help you finish large areas quickly, just be careful to cover the rest of the bathroom so the spray paint doesn’t stain glass or tile.
