Pentaryl – 1 Quart (32 oz.)This is a common question from woodworkers using Pentacryl to stabilize their wood. There are 2 key factors to using Pentacryl successfully:

  1. Completely saturate the wood with Pentacryl (by soaking it or brushing it on)
  2. Dry the wood SLOWLY

By drying the wood slowly, we mean let the Pentacryl treated wood dry naturally in an area away from a lot of air movement, heat source, direct sunlight, etc. Smaller pieces can be put in a paper bag, a cardboard box or even dried in a pile of wood shavings, while larger pieces can have cardboard taped to the sides or End Grain Sealer applied to slow down the surface drying. See our step-by-step guide to treating a cross-cut section of wood with Pentacryl.

End_Grain_SealerThere is not a general answer to drying time as the time it takes wood to dry varies considerably depending upon the original moisture content, the type and size of the wood (it’s thickness) and the temperature and humidity in the drying area. If the wood is a turning or cross-cut section (cookie) that is thin, it may be dry enough to finish in 1-3 months. If the piece is a large carving or block of wood, it could take 1-3 years to completely dry and stabilize.

To help determine if the wood is dry, a moisture meter can be used as Pentacryl will not effect the reading. Keep in mind though, that a moisture meter will only read the moisture level of the wood surface (as far as the prongs will go) and is not a good indicator for measuring the inside moisture content of large pieces.

By displacing the moisture in the wood, Pentacryl does help to speed the drying process by up to 30%. It is not the Pentacryl that you are waiting to dry, it is the water in the green wood.

Pentacryl is a great choice for a wood stabilizer, so just be careful and patient with the drying process so all your efforts won’t be wasted on cracked wood.
