What is it?
It's a wax emulsion for sealing the ends of timber, logs etc. It can go on green or dry timber and helps reduce end cracking. Log Shield takes over from the old Mobil CerM which is no longer available.

Wax Emulsion Sealer Overview:

Few surface coating products have been as beneficial to wood turners trying to successfully season green timber, as modern wax emulsion sealers. These sealers are specifically formulated to control the rate of moisture loss in green timber by forming a durable wax membrane between the exposed end/side grain and the surrounding ambient atmosphere.
The goal is not to prevent moisture from moving through the wax coating, but instead to slow the rate of moisture evaporation, thereby reducing drying defects like end grain checking and warping.



Wax emulsions must be applied as soon as the log is cut for maximum protection. Application of the sealer to dried log surfaces will reduce the overall protection level achieved and may not stop the continued progression of any existing surface checks.


Log Shield is a microcrystalline wax-based coating. It contains microcrystalline wax, water and a surfactant it is also milky-white in appearance. Non-staining
The inside and outside end grain portions of these bowls were first wet-turned from Ancient Kauri then treated with log shield my success rate of usable bowls went from 30% to 88%
Many joiners, and milling operations use this product.
