The method of finishing BLACK WOOD Worktops
 |
the baseboard is a BLACK WOOD and is of high density. The baseboard material is of black colour, 11,6 mm thick |
|
the work surface is covered with HPL laminate (with protective film) |
|
the underside of the top is covered with backing paper to prevent deformation. The top also provides additional protection against moisture |
|
on the underside of the top, UV varnish is applied along the entire length, on both sides, approximately 10 cm from the edge. This is done to protect the product against moisture and the effects of water vapour |
IMPORTANT NOTES!
All visible (external) worktop edges necessarily have to be protected in order to close their surface and protect them against dirt, abrasion and water penetration, as well as for aesthetic reasons (use of wax deepens the black colour of the base board). For this purpose, we recommend:
-
use of colourless coatings like: hard wax, varnish. Warning: We particularly recommend use of OSMO hard wax.
-
edgeband, e.g. ABS one, glued with the use of polyurethane glue.
The BLACK WOOD worktop should not be used for suspended sinks.
All important information and recommendations for installation and use are contained in "SWISS KRONO BLACK WOOD Worktop Processing, Installation and Use Manual".
