To set painted rocks, especially for outdoor display, you'll need to seal them with a protective varnish. Here's a breakdown:
Sealing Painted Rocks
While some paints, like Life of Colour acrylic paint pens, dry permanently on the rock surface and may not require sealing for indoor display, sealing is essential for outdoor use. Sealing painted rocks offers two key benefits:
- Protection: It creates a barrier against the elements, preventing paint from fading, chipping, or washing away.
- Enhancement: Many sealants provide a glossy finish, enhancing the colors and overall appearance of your painted rock.
How to Seal Painted Rocks
-
Choose your sealant: Use either a spray or brush-on gloss varnish, as recommended for outdoor use.
-
Apply the sealant:
- Spray Varnish: Hold the can about 10-12 inches away from the rock and apply thin, even coats, allowing each coat to dry before applying the next.
- Brush-on Varnish: Apply a thin, even coat using a soft brush, and allow it to dry before adding additional coats if needed.
-
Drying time: Allow the sealant to dry completely according to the manufacturer's instructions. This could take a few hours.
-
Multiple Coats: For enhanced protection, apply multiple thin coats instead of one thick coat.
Important Considerations
- Ventilation: When using spray varnish, work in a well-ventilated area or outdoors to avoid inhaling fumes.
- Test: Before applying the sealant to all your rocks, test it on a sample to ensure compatibility and desired finish.
- Clean Rocks Ensure your painted rock is completely dry and clean of any dust or debris before applying the sealant.
- Sealant type As the reference states a gloss varnish is recommended for outdoor use, other varnishes may not be as effective.
