Frequently Asked Questions for Pentacryl™
“The Wood Stabilizer”
Pentacryl, a compound of modified polymers, was originally developed for the treatment of waterlogged wood. It has since been marketed for woodcarving, woodturning, furniture making and other general woodworking to keep green wood from cracking and splitting as it dries. Pentacryl is formulated to penetrate green, wet wood as the moisture in the wood helps the penetration.
Pentacryl works by completely saturating the wood cells and displacing the water. Once the wood dries, the Pentacryl leaves a thin coating on the wood cell walls. This process keeps the cells from shrinking, which reduces cracking, checking and irregular drying. Shrinkage is reduced up to 600% depending on the orientation of the wood grain.
Pentacryl 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.
Tests have been carried out for over 17 years with excellent results. Many types of wood have been treated including Eastern White Pine, Basswood, Tupelo, Walnut, Apple Wood, Hawthorne, Cherry, Rock Maple, Soft Maple, Ash, Madrone, Bamboo, Exotic Wood and others.
Pentacryl can be brushed on or the wood can be immersed (soaked) into a 100% solution of Pentacryl. Although soaking is the preferred method, excellent results are still obtained by using the brushing method.
When the Pentacryl treated wood has dried, the wood can be finished with various finishes. Easy soap and water clean up.
