Welcome to dickblick
For hundreds of years the world has marveled at the works of art created by the "Old Masters" during the Renaissance. Not only did their achievements arise from training and talent, but also from the techniques they used in preparing their materials. It wasn’t until the 20th century that some of these formulas were rediscovered.
Grumbacher has continued this tradition in the manufacture of its painting mediums, by assuring that the original paint attributes are enhanced, not compromised, by their use. Grumbacher mediums thicken or thin paints without harming their adhesive, binding, or film-forming qualities, and allow artists to achieve myriad effects such as increased flow and rapid or slow drying. They also have been proven to guard against yellowing and cracking over the course of many generations.
Alkyd Painting Medium
The ultimate alkyd painting vehicle, Grumbacher Alkyd Painting Medium lubricates oil color for easier surface glide, allowing for up to eight hours of painting with little, if any, brush drag. A thixotropic painting medium (the more you stir, the more fluid it becomes), it produces rich, transparent, luminous glazes and may be diluted with any conventional oil painting solvents. Odorless, non-yellowing, and archival, it dries to the touch and is ready for overpainting within 12 hours.
Grumbacher Cobalt Drier is the only siccative that has been scientifically proven to be the least harmful to use for fine art painting. Cobalt Drier speeds drying of oil colors and oil painting mediums. Because it is extremely strong, Cobalt Drier should be used sparingly by applying it in drops. It should not be mixed directly into oil paints, but first mixed into an oil painting medium, which can then be added to the paint. Cobalt Drier should always be tested before using it in a painting.
Copal Painting Medium
A traditional 19th century painting medium prepared especially for hobbyists and decorative painters (i.e. tole painters), Grumbacher Copal Painting Medium is made with a modern synthetic copal resin, and has all of the manipulative and drying characteristics of the original 19th century preparation. When added to oil colors, Copal Painting Medium improves flow, accelerates drying, and imparts hardness and a high gloss to the dry paint film. Because this product may cause yellowing and darkening of the colors with time, its use is recommended for occasional or impermanent painting only. Dilute Copal Painting Medium with Pure Gum Spirits of Turpentine or Grumtine only.
Damar Liquid Varnish
This is a pure gum damar that is used to enrich dry oil paintings. Quick-drying and permanent, it provides a transparent high gloss finish that also protects oil paintings from dirt, moisture, and scuffs. When used properly, it will not “bloom” or cloud with age. Apply it when paintings are thoroughly dry (between 6-12 months). It cleans up easily with paint thinner or other mild solvents.
Damar Retouch Varnish
Damar Retouch Varnish is a spray damar varnish for use during intermediate stages of development in an oil painting to even out the gloss of unfinished works, or to revive sunken in or dry areas to aid in accurate color comparison for further painting.
A colorless, genuine Damar varnish for use as a final protective coating on thoroughly dry oil paintings. It brings out the beauty of oil colors with an soft, even, matte finish, while protecting paintings from dirt, moisture, and scuffs. Designed to provide a uniformly fine mist, it quickly dries to a matte or gloss finish that is transparent, permanent, and will not “bloom” or cloud with age.
Apply when painting is completely dry, normally within six to 12 months. One coat covers; allow five minutes between coats if a heavier application is desired. Damar Varnish contains Damar gum, turpentine, and isopropyl alcohol.
Grumbacher Japan Drier is a reliable alkyd resin-based liquid siccative intended for use by sign painters, artisans, and craftspeople. Japan Drier is not generally recommended for fine arts applications because it has a tendency to yellow and darken oil colors over long periods of time. It is an ideal medium for oil gilding. Simply apply Japan Drier to an appropriate surface and allow it to dry to a high tack, then apply gold or silver leafing, smooth, and burnish.
MG Underpainting White
This permanent, fast-drying Titanium White oil paint is designed for use in underpainting or in wet-in-wet (alla prima) painting. Specifically formulated to create a lean, dry paint film, MG Underpainting White has enough tooth to readily accept glazes. Other uses include creating surface textures and impasto techniques. In normal applications, MG Underpainting White dries to the touch in 4 to 6 hours and may be painted over immediately. Need to control drying time? Mix MG Underpainting White with oil colors or mediums. To dilute, mix it with Pure Gum Spirits of Turpentine or Grumtine only. Petroleum solvents and paint thinners and odorless paint thinners are not compatible with this product. Mixtures of MG Underpainting White in excess of 1:1 will result in a brittle, dry paint film.
This is a flexible, durable paste for creating textured surfaces to be over-painted with oil or acrylic paints. Apply it to canvas, wood, cardboard, plaster, concrete, masonry, and other surfaces.
Oil Painting Medium I
For use with artists’ oil colors where a matte finish is desired, this medium is especially useful for under-painting on an absorbent gesso ground or for mural work. Add it directly to oil color in small quantities for increased fluidity and enhanced ease of application. Composed of poppy oil, copaiba, balsam, and solvent, it does not affect the brilliance of even the most subtle tints.
Oil Painting Medium II
Formulated especially to improve flow, retard drying time, and impart a high gloss finish to the dried paint film, this is the ideal painting medium for alla prima (wet-in-wet) painting techniques. For best results, add it to paint in small amounts until the desired consistency is obtained. It contains D-Limonene and petroleum distillates, and may be diluted with pure gum spirits or turpentine.
Oil Painting Medium III
Dilutes oil color to speed drying time and improve paint flow. Add it directly to the color in small quantities. It's perfect for detail work.
Pale Drying Oil
This safe, non-toxic medium is specially formulated for use by hobbyists, decorative painters, and other artisans to reduce the consistency of tube oil colors and accelerate drying time. Because excessive use causes severe yellowing and brittleness of the paint film, Pale Drying Oil is not recommended for fine art applications.
Picture Varnish, Gloss
A final varnish for dry oil and acrylic paintings that protects them from dirt, moisture, and scuffs. Crystal-clear when applied, it quickly dries to a gloss finish that is non-yellowing and flexible. It can be easily removed with paint thinner or other mild solvents. Apply when painting is completely dry, normally within three to five days for acrylic paintings, and six to 12 months for oil paintings. One coat covers; allow five minutes between coats if a heavier application is desired. 11 oz (311 g) aerosol can.
Picture Varnish, Matte
A final varnish for dry oil and acrylic paintings that protects them from dirt, moisture, and scuffs. Crystal-clear when applied, it quickly dries to a matte finish that is non-yellowing and flexible. It can be easily removed with paint thinner or other mild solvents. Apply when painting is completely dry, normally within three to five days for acrylic paintings, and six to 12 months for oil paintings. One coat covers; allow five minutes between coats if a heavier application is desired. 11.25 oz (318 g) aerosol can.
Grumbacher Poppyseed Oil is a purified, non-yellowing oil painting medium. When mixed with oil colors, it slows their drying rate, allowing ample time for blending and other wet-into-wet techniques. It also makes colors smoother, improves their flow, and helps level out brushstrokes. It may be diluted with Grumtine, pure gum spirits of turpentine, or odorless paint thinner.
Sun-Thickened Linseed Oil
A heavy-bodied purified oil that is thicker than regular linseed oil but not as thick as stand oil, Grumbacher Sun-Thickened Linseed Oil is designed for use in preparing oil painting mediums. It exhibits an excellent resistance to yellowing and is extremely flexible. Use Sun-Thickened Linseed Oil to improve flow and increase gloss. Pre-dilute it with Pure Gum Spirits of Turpentine, Grumtine, or Odorless Paint Thinner.
Accelerate the drying time of your painting with this clear and colorless colloidal oil painting medium. Grumbacher ZEC Medium maintains the consistency and hue of the colors and holds any desired texture. In normal applications, paintings dry to the touch in 4 to 6 hours. ZEC should be diluted with Pure Gum Spirits of Turpentine or Grumtine only. It is not compatible with petroleum solvents, paint thinners, or odorless paint thinners. Mixtures of ZEC in excess of 1:1 will result in a brittle, dry paint film.

My favorite for 30 years
Grumbacher years ago packaged this in convenient half pint tins instead of tiny bottles. Wish they still did. That's the only thing I don't like about it. I use it for extensive glazing and it is wonderfully transparent, glossy, and quick-drying.

Excellent product which met my needs.

Ideal for glazing my acrylic paintings.
Sun Thickened Linseed Oil
from San Jose, Ca.
Grumbacher Sun Dried Linseed Oil has been a terrific product for the 50 years I've used it. It's by far the smoothest, highest quality oil I've used. It regularly cuts drying time to 24-36 hours when applied, all the while providing everything you could wish for in an oil additive. Other brands of the same item are fine, but this one has become my favorite based on its consistency and ease of use. I've never been dissatisfied, nor found any brand oil paint that was not completely compatible with it.
I would buy from you again

Gumbacher oil paint medium
from Russell On. Canada
Just bought this for the first time and have used it a couple of times so far and find it dilutes the oil paints nicely. The paint paint goes on smoothly and I find this product works well. Will know more once I use it more.
Love this stuff
from West Jordan UT
I use medium III and love it. I have been using with my oil painting for over 20 years nothing compares. It is getting harder to find so I am glad blick has it.I do wish it was less expensive but still keep coming back to it.
Cobalt Drier for Relief Printing Inks
from Falmouth, MA
For those wondering about using cobalt drier with water wash oil-based relief or etching inks, you will be happy to know it works very well. Word to the wise, due to toxicity, use very sparingly. I use an eyedropper to add it to my ink, mixi it well, and then roll out. Use in well-ventilated room. Wash plates and rollers as usual, but for extra caution, wear rubber gloves. Great price! PS. Though the description of product tells you it cannot be shipped through USPS, mine did arrive with other products, through USPS.
Japan Driers are the best!
By Crazy Old Man Bob
from Absecon, NJ
I have been using this product (Japan Driers) mixed with oil paints to make an antiquing glaze for carvings I make. I have been using it in this manner for nearly 30 years & have never found anything that works better.
I love this product. I have used it for a few years.
from Queens, New York
I use this product for oil painting. It is great for a workshop because it makes it possible to paint in oil quickly. This product will dry the first layer so you can continue to paint. You must be careful not to use to much of it.
