Frequently Asked Questions Regarding Wood Juice

“The Dry Wood Stabilizer”

Wood Juice is a compound of modified polymers. It is formulated to penetrate and stabilize dry to semi-dry wood.

Wood Juice works by completely saturating the wood and displacing the remaining water. Once the wood dries, the Wood Juice leaves a thin coating on the cell walls of the wood. This process keeps the cells from shrinking, which reduces future cracking, checking and irregular drying. Shrinkage is reduced up to 600% depending on the orientation of the wood grain and how dry the wood is prior to treating with Wood Juice.

Wood Juice is non-toxic, non-hazardous, does not contain silicone, will not discolor the wood, is non-hygroscopic (meaning it will not retain water), will not oxidize, decompose or migrate in the wood when exposed to different degrees of temperature and relative humidity. It also contains a UV protectant.

Wood Juice can be brushed on or the wood can be immersed (soaked) in Wood Juice (do not dilute). Although soaking is the preferred method, excellent results are still obtained by using the brushing method.

The following are some of the most common questions and answers relating to the use of Wood Juice.

Wood Juice can be cleaned off/up with soapy water, SOLVITOL, or any mineral solvent.
95% of the odor will dissipate. The time it takes depends upon the size and type of wood and the length of time it takes for the wood to completely dry.
Yes. Wood Juice treated wood can be wood burned, however, it is recommended that the wood be completely dry after being treated with Wood Juice prior to wood burning.
It will help. Since Wood Juice will reduce the shrinkage of the wood, it will help to keep the wood from pulling away from the bark. However, there is no guarantee that the bark will stay on. For best results to keep bark on, the tree should be cut during the dormant period (winter) when the sap stops running and the wood has hardened off.
No. Wood Juice has been run through 16 freeze-thaw cycles, some solids may settle out after being frozen 2-3 times, but will readily disperse when brought back to room temperature and shaken well.
Although Wood Juice is considered non-toxic, it is not registered as food grade. Therefore, we cannot endorse that it can be used on items intended for use with food.
Yes, Wood treated with Wood Juice can be glued. Tests have been successful using carpenter ‘s glue, cyanoacrylates, and epoxies. The shear strength, however, has not yet been determined. Again, it is important to clean the wood surfaces with solvent or Solvitol and be sure that the solvent has completely evaporated (dried) prior to gluing.
In some cases, it may alter the color slightly, however, it usually just enhances the wood grain more.
Yes. Wood Juice will stabilize rotted or spalt wood. However, it will not harden soft areas. See information on Polycryl for hardening soft areas of spalted or punky wood.
Yes. The wood will turn and carve easier because Wood Juice also acts as a lubricant for your tools until it dries. Note that before sanding, the wood should be completely dry. If the sand paper clogs up or is gummy, it is an indication that the wood is not dry yet.
Depending upon the type of wood, it will weigh only slightly more when the wood is dry. A cubic foot of wood will weigh approximately 10-12 ounces more than wood that was untreated.
Using the soaking method, 2-3 days is generally sufficient for a piece 1-4 inches thick. It will not hurt the wood to soak it a little longer.
No, too much cannot be applied. The wood will only absorb so much. After treatment, any excess can be cleaned off the surface with Solvitol. Note: If using the soaking method, any Wood Juice left over in the soak can be reused on other wood.
In most cases, the wood should be completely saturated with Wood Juice. In some cases however, woods that are quite stable may only require several coatings to the surface, while other woods with wild grain, a lot of tension, or those that are unstable such as fruitwoods, require full saturation. The individual user will have to determine whether or not to completely saturate the wood.
The amount of Wood Juice absorbed into the wood will depend upon the type and size of wood. For very dense grained hardwoods, it will take as little as 1 ounce per board foot and for very soft open grained wood, it will take as much as 8 ounces per board foot. Refer to the wood calculator on our website to help determine the amount needed for your size and type of wood.
Yes, Wood Juice will absorb all the way through the wood. The time it takes depends upon the type and size of the wood. Keep in mind that most of the absorption is through the end grain. When using the brushing method, keep applying until the wood will no longer absorb Wood Juice. In between brushing applications, the wood should be wrapped in plastic in order to help absorption and prevent premature evaporation. Remove the plastic during drying – this will allow the wood to breathe and prevent mold growth.
A colorant can be added to Wood Juice. Analine dyes, oil base dyes and stains, and pigments can be mixed with Wood Juice. The amount used depends upon the desired effect.
Yes. Wood treated with Wood Juice can be finished with urethane varnishes, water based varnishes, lacquers, tung oil, linseed oil, and waxes – all have been successfully used. The wood can also be stained with analine dyes or oil stains. Be sure that the Wood Juice has thoroughly dried and to lightly clean the surface of the wood with a solvent such as Solvitol, mineral spirits, or acetone before finishing. Be sure the solvent has dried prior to finishing the wood.
There is not a specific answer to drying time. Drying time differs depending on the temperature, relative humidity, type of wood and its thickness. If the piece is a turning that is finished thin, then it may be dry enough to apply a finish in 1-3 months. If the piece is large, like a carving or cross-cut section, it may take 1-3 years to completely dry. Note that the wood must be dried slowly (especially hardwood) in an unheated area away from direct sunlight and any air movement. To help slow the drying time, wood can be covered with a cardboard box (leave a gap on the bottom to allow air to still reach the wood). Larger pieces can also be coated with the End Grain Sealer to slow down and help even out drying.
Both products are wood stabilizers. However, they are each formulated differently. PENTACRYL was developed to treat green or freshly cut wood. The wetter the wood, the better PENTACRYL will work. Wood Juice is formulated to treat dryer wood with a lower moisture content. It is developed to compensate for the difference in the moisture content of the wood. When to use Wood Juice: Low Moisture Content: A general rule is to use Wood Juice if the moisture content in the wood is less than 30%. Naturally Stable Wood:Wood Juice can be used on some green wood that is stable by itself such as Basswood. Thin Cuts of Wood: Turned wood that has thin walls (such as bowls), wood that is carved thin or wood that is cut thin (such as veneer) is good for Wood Juice since much of the tension is relieved in these cuts. Small Pieces: Wood Juice can be used on small pieces of dry or green wood, such as Fruitwoods. Again, small, thinner pieces have less tension. Older Wood: Use Wood Juice on older wood that is dry and you would like to condition and rejuvenate it.
