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.
Tip: 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 joineries, and milling operations use this product.
APPLICATION DETAILS
Brush the end grain free of any loose surface material prior to application.
Liberally apply a single coat of End Seal to the end grain.
Thinning, if required, may be achieved by thorough stirring. Water should not be added, as this will reduce the effectiveness of End Seal.
Application of the sealer to ends of timber posts, beams, log surfaces, bowl blanks that are not coated with anything will help the overall protection level and may help stop surface checks, etc. although we advise that End Seal must be applied as soon as the timber is available for maximum protection .
Be cautious as not to get End Seal on any ascetic, dressed faces
Use a dedicated speed brush or brush that can be disposed of on completion of works as the nature of the product will not allow cleaning.
Log Shield/End Grain is a wax emulsion for sealing the cut ends of timber posts, beams, wet turned woodturning, timber slabs etc and is an effective and easy to use preventative reducing checking in sawn timbers, It can go on green, dry. Also Used to stop sap staining before milling.
Used in architectural builds where exposed ends on beams, cladding or screens made of Cedar, etc need ultimate protection for low maintenance and timber stability.
This sealer is specifically formulated to control the rate of moisture ingress and loss in timber by forming a durable wax membrane between the exposed end/side grain and the surrounding ambient atmosphere, thereby reducing defects like end grain checking and warping.
- Protects against end checking
- Easy to apply by brush
- Exceptionally low water permeability
