Frequently Asked Questions for Polycryl

Q. Why is it necessary to put on different mixtures of Polycryl and water?

A. No, Polycryl is light fast and does not yellow or darken with time.

Q. What if the wood is soft in some areas and hard in others? Will Polycryl work for this application?
A. Polycryl is a large molecular polymer and will only penetrate the soft areas. Any build up of Polycryl on the hard areas can be wiped off with a damp cloth.

Q. How fast can I dry wood treated with Polycryl?
A. Wood treated with Polycryl should be dried very slowly. Remember that moisture has been added to the wood. Rapid dry can cause checking and/or cracking. A good method of slowing down the drying is to place the treated wood in a cardboard box and fold the top together. This will slow down the drying yet allow some air movement.

Q. What is the best method of applying Polycryl?
A. Usually brushing on the Polycryl is the best method. Keep in mind that most of the absorption is through the end grain. If you are treating bowls, pour the first diluted solution into the bowl and periodically add more Polycryl to the solution until the desired concentrate has been reached. Be sure to keep the bowl cover with plastic during to treatment to prevent evaporation.

Q. Does freezing hurt the Polycryl?
A. No, freezing will not hurt the Polycryl. Be sure to bring the Polycryl to room temperature before using. Note: the wood should also be at room temperature to insure proper penetration.

Q. What is the shelf life of Polycryl?
A. Polycryl has an indefinite shelf life.
