M2 is a solvent-borne water repelling penetrating wood oil sealer. The product has been formulated specifically for application on low to medium density hardwoods, Although the product can also be applied to high-density wooden surfaces. Application: Brush, Spray or Dip Spread Rate: Approximately 10-12m² Please Note:  Darker Colours tend to absorb more solar energy and therefore thanks to expansion and contraction will cause more thermal stress on the structure of doors and window frames. This added stress will in turn lead to cracking of timber and delamination essentially destroying the structural integrity of the products it is applied to. K Parker Joinery cannot be held liable for damages as a result of the application of unsuited paints and stains. The use of dark stains and or paints on surfaces which are exposed to sunlight (even partially) will thus void the warrantee of products they are part of.
