In general the best way to seal rocks paintedwith acrylic paint is going to be with a spraysealer. Some acrylic paints are self-sealing,though, and won't need any sealer at all! Self-sealingpaints include FolkArt Outdoor paint, FolkArtMulti-Surface Paint and Martha Stewart multi-surfacepaint.
In this way, how do you seal a rock?
7 Things Not To Do When Sealing Your Rocks
- Hold the can too close. Most spray sealers should be held atleast 8″ from your rocks.
- Spray a heavy first coat.
- Spray a heavy second coat.
- Let them dry in the sun.
- Seal your rock right away.
- Only seal the top.
- Seal rocks on a windy day.
- Use a wet cloth to clean the wood. Leaving dirt or otherparticles on the wood can keep it from properly absorbing thepaint, primer, and sealant.
- Apply 2 coats of sealant onto the raw wood.
- Apply a coat of primer to help the paint adhere to thewood.
- Allow the wood to dry and cure.
Besides, do you seal rocks before painting?
Seal the rock before painting on it. Use aclear brush on or spray sealer. Finish off your rockswith a coat (or two or three) of Mod Podge Outdoor. Thiswill help protect your beautiful painted rocks fromthe elements.
Use acrylic paints from a tube, such as Liquitex,or a paint made for outdoor use such as Plaidpaint. An acrylic patio paint, however, is ideal. ItIs ideal because the paint is made to handle poroussurfaces, like rocks, and weather the outsideelements.
