It is crucial to protect your painting from dust. Using varnish is an effective way to keep it protected and prevent damage from UV and moisture. The most common causes of fading are strong UV rays and moisture. Moreover, the paint on your canvas painting will begin to yellow after prolonged exposure to the sun. It is best to use a UV filtering acrylic plexiglass to protect it from fading and moisture damage. It is also important to ensure that the room where you hang your painting is free from direct sunlight or any other source of light. Alternatively, you can place a curtain over the canvas painting to keep it in good condition.
Another way to protect your canvas painting from dust is to cover it with a layer of acrylic varnish. This will give it a glossy finish and is super strong. It is best to mix the two parts thoroughly before pouring on the painting and making sure it is evenly covered. A small amount of water is enough to protect your canvas from the effects of acrylic varnish, but the water or cleaning products can damage the material. It is recommended that you seek professional help when your painting is badly damaged.
The best way to protect canvas paintings is to ensure that the air around them is not too dry or too humid. Excessive humidity can cause a painting to warp and crack. So, it is best to buy a humidifier to get rid of excess moisture and a dehumidifier to keep the room in the right humidity. In order to avoid excessive moisture, it is advisable to check the relative humidity of your room before applying any acrylic resin varnish.
