POLYCRYL CONCENTRATE
The Wood Fortifier

POLYCRYL is a large molecular weight acrylic polymer that will fill and strengthen punky or spalted wood. POLYCRYL is water-soluble and penetrates best when wood is green. The softer the wood, the better the penetration. POLYCRYL will not penetrate hard wood. POLYCRYL should be used before PENTACRYL.

DIRECTIONS NOTE. The wood should be roughed carve or turned first in order to obtain the best penetration. Add 15% POLYCRYL to hot water and mix well. it is important to use a very weak solution at first. This will allow the next application to penetrate deeper. Apply a liberal amount of POLYCRYL solution to fill in the open pores until the wood will not absorb anymore POLYCRYL. Keep the wood wrapped in a plastic bag allowing the solution to penetrate overnight. Each day, increase the solution by an additional 15% POLYCRYL and again wrap in plastic bag and allow it to penetrate the wood overnight (it is very imports to keep the wood wrapped in plastic until the process is finished.) Repeat this procedure until the wood will not absorb any more POLYCRYL solution. (Note: a solution of up to 50% of POLYCRYL can be used for extremely soft or punky wood.) After wood has dried, it must be seated with a finish.

Disclaimer: Being that wood is a natural material and is susceptible; to varying degrees of shrinkage, reaction, deterioration and because se of varying climatic conditions, varying experience of the user and may be applied under conditions beyond our control, as seller, we make no warranty expressed m implied as to this material or its use.

PENTACRYL
TECHNICAL SHEET

Pentacryl, a compound of Siliconized polymers, was originally developed for the treatment of waterlogged wood. It has since been marketed for woodcarving and woodturning to keep green wood from cracking and splitting. PENTACRYL will not discolor the wood, is non-hydroscopic, will not oxidize, decompose or migrate in the wood when exposed to different degrees of temperature and relative humidity.

Tests have been carried out for over 3 years with excellent results. Many types of wood have been treated including Eastern White Pine, Basswood, Tupelo, Walnut, Applewood, Hawthorne, Cherry, Rock Maple, Soft Maple, Ash, and others. Since fruitwoods are very difficult to dry, we have listed some tips in treating some of these difficult to dry woods later in this write UP.

PENTACRYL can be brushed on, sprayed on, or the wood can be immersed into a 100% solution of PENTACRYL. Although soaking is the preferred method, excellent results are still obtained by the brushing or spraying methods.

When the wood that has been treated with PENTACRYL has dried, the wood can be finished with various finishes.

Listed below are some of the most common questions asked and the answer relating to it.

Q: How long will it take for the wood to dry when using PENTACRYL?
A: There is no way to give a specific answer to drying time. Drying time differs depending on the temperature, humidity, type of wood, and its thickness. If the piece is a turning that is finished thin, then it may be dry enough to finish in 2-3 weeks. If the piece is a carving that is large, it may take 1-3 years to completely dry. By displacing moisture in the wood, PENTACRYL helps to speed up the drying process.

Q: Can wood treated with PENTACRYL be finished with conventional finishes?
A: Yes. Wood treated with PENTACRYL can be finished with conventional finishes. Urethane varnishes, water borne varnishes, lacquers, tung oil, linseed oil, and waxes have all been successfully used. The wood can also be stained with analine dyes or oil stains. The two keyfactors are to be sure that the wood has thoroughly dried and to clean the surface of the wood with mineral spirits, acetone, or lacquer thinner before finishing. (See SOLVITOL on product sheet for alternative solvent.)

Q: Can a colorant be added to PENTACRYIL?
A: Yes. A colorant can be added to PENTACRYL. Analine dyes, oil base dyes and stains, and pigments can be mixed with PENTACRYL. The amount used depends upon the desired effect.

Q: Does PENTACRYL absorb all the way through the wood?
A: Yes. PENTACRYL will absorb all the way through the wood. The time it takes depends upon the type of wood and size of the piece. Allow one day for every inch in length if using the soak method. When using the brushing or spraying methods, several applications per day can be applied until the wood will not absorb anymore. In between applications, the wood should be kept wrapped in plastic in order to prevent moisture from evaporating. The moisture in the wood actually helps carry the PENTACRYL through the wood. Most of the absorption is through the end grain.

Q: How much PENTACRYL does it take?
A: The amount of PENTACRYL the wood will absorb depends upon the type of wood. For very dense grained hardwoods, it will take as little as I ounce per board foot and for very soft open grained wood, it will take as much as 8 ounces per board foot.

Q: Does PENTACRYL have to be absorbed all the way through the wood to be effective?
A: PENTACRYL does not always have to be absorbed all the way through the wood to be effective. Some woods that are quite stable may only require several coatings to the end grain, while other woods with wild grain, tension or those that are unstable such as fruitwoods, require full saturation. Wood that is surface treated only will not develop uneven drying or radical shrinkage. PENTACRYL will allow moisture to pass through it. A determination will have to be made as to whether or not to completely saturate the wood by the individual user.

Q: Can too much PENTACRYL be appllied?
A: No. Too much PENTACRYL cannot be applied. The wood will absorb just so much. Any excess can be cleaned off the surface. Note: if using the soaking method, any PENTACRYL left over in the soak can be reused.

Q: Will wood treated with PENTACRYL weigh more when it is dry?
A: The wood 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.

Q: Will turning and carving be easier with wood treated with PENTACRYL?
A: Yes. The wood will turn and carve easier because PENTACRYL also acts as a lubricant until dry.

Q: Will PENTACRYL stabilize rotted or splated wood?
A: Yes. PENTACRYL will stabilize rotted or spalted wood. However, it will not harden soft areas. (See POLYCRYL on product sheet for hardener.)

Q: Does PENTACRYL reduce shrinkage and distortion?
A: Yes. PENTACRYL does reduce the shrinkage by 1-2%. Distortion is also significantly reduced.

Q: Does PENTACRYL change the color of the wood?
A: In most cases, there is little or no color change. In some white woods, PENTACRYL may alter the wood to a light creamy color; however, the color change is only on the surface. After the wood has dried, the surface can be sanded, turned or carved to remove any discoloration.

Q: Can PENTACRYL be used to treat fruitwoods?
A: Yes. PENTACRYL can be used to treat fruitwoods. For thin turnings, no special precautions are necessary. For thick turnings or large carvings, the wood must be allowed to dry very slowly after treatment with PENTACRYL.

Two methods we have found successful are:
1). After treatment and turning or carving, place the wood piece in a paper bag and seal it closed. Twice each day, open the bag for 1/2. hour intervals. Repeat this process until most of the moisture has dissipated.
2). Be sure drying conditions are not to hot or to dry. Ideal drying temperature is 60'-70'F and 50 -55% relative humidity.
3). Another alternative is to let the piece dry in the freezer. After the wood has been treated with PENTACRYL, let the wood start drying for several days. Next, place the piece in a cardboard box and place it in the freezer. 'Me water molecules will evaporate in the freezer. PENTACRYL will prevent swelling and cracking in the freezer. This method works especially well with wild grained woods.

Q: Can wood that has been treated with PENTACRYL be glued?
A: Yes. Wood treated with PENTACRYL 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. Be sure that the solvent has completely evaporated before gluing.

Q: Can PENTACRYL be used on salad bowls and eating utensils?
A: Although PENTACRYL is considered non-toxic, it is not registered as food grade. Therefore, we cannot make any claims that ft can be used on items intended for use with food. We are however, working on a food grade PENTACRYL.

Q: If Pentacryl freezes, will it loose its properties?
A: No. PENTACRYL has been run through 16 freeze-thaw cycles, some solids settle out after being frozen 2-3 times, but will readily disperse when brought to room temperature and shaken well.

Q: Can wood treated with PENTACRYL be woodburned?
A: Yes. Wood treated with PENTACRYL can be woodburned, however, it is recommended that the wood be completely dry after being treated with PENTACRYL before woodburning.

Q: Does the odor of PENTACRYL remain in the wood after the wood has dried?
A: No. The odor does not remain. It will completely disappear. The time it takes depends upon the type of wood, size, and the length of time it takes for the wood to completely dry.
