Graining with Acrylics
Jo Sonja are the paints I have grained with, and so can give you a formula which was successful for me. You will need the pigments plus three of the mediums and they are: sealer, kleister and retarder.
First mix the mediums together: 1 part sealer to 2 parts kleister to 3-4 parts retarder. Now add the pigment. It should measure 1 + 1/2 the amount of the combined mediums. Apply to the floor, or floorcloth, one side at a time (which you will isolate using 3M™ automotive tape – burnish the edge well and remove while the paint is still wet). Apply with a large brush and “mottle” it with a large, barely damp, sponge. Apply your graining tool to create the desired effect. While still wet, you can soften the effect of the grain using a large, VERY soft brush which is passed back and forth on the diagonal barely “kissing” the grain. Work opposite sides to allow drying time before taping over grain. A hair drier can aid you in this.
I credit Linda Lefko with giving me this formula. She says it will work over oil as well as acrylic.
Graining with Oil Glazes
Several major companies put out glaze coats. Oil glazes give a lovely transparant look which has yet to be achieved with acrylics. This will work over latex or oil base coats. If you try this, follow their guidance.
Vinegar Graining with Powders (Old Time Method)
This is the historic method, but modern substitutes create the appearance with a greater likelihood of success. This works on a latex or oil base background. Sand the background very smoothly (oil base backgrounds especially), and wipe back with vinegar before attempting to grain.
White vinegar (or stale beer)
Karo corn syrup (or stale beer)
Formula (This makes about 1 pint):
1 cup dry graining powders
2 cups white vinegar (scant)
1 Tablespoon Karo™ corn
Mix at least 3 hours before using. This lasts well – up to three years, if tightly covered.
Wipe on with a brush sparingly but to cover. Allow a moment to “dull,” and then apply graining tool. If “crawling” or beading, wipe off with vinegar, dry and try again.
