Black Japan Floor Finish

Semi-Transparent Traditional Black Japan Flooring Stain & Varnish

Black JapanTM Floor Finish is an oil based interior floor finish which combines a traditional Black JapanTM stain with a professional clear polyurethane for a one-step ‘Black Japan look’ and durable protection on interior timber and parquetry floors.

The semi-transparent coating adds rich colour whilst allowing the grain pattern of timber to remain visible.

surface preparation

New or bare timber/cork
Punch exposed nails below the surface. Holes and imperfections should be filled with timber putty. Sand timber to an even, smooth surface. Vacuum and wipe to remove dust. Prepare uncoated cork tiles in accordance with the supplier's recommendation.  

Previously Coated Timber
Previously coated surfaces need to be sanded back to bare timber. Remove all sanding dust before coating.



Stir Black JapanTM Floor Finish thoroughly before and during use with a flat blade stirrer, being careful not to introduce bubbles.

If using more than one can of the same colour to complete a job, combine both cans and stir thoroughly.

Test colour on an off-cut or inconspicuous area prior to coating the whole job to ensure satisfaction with colour choice.

Apply with a Feast Watson Floor Finish Applicator, brush or short nap mohair roller. Work along the whole length of 3 to 4 floorboards at a time, maintaining a wet edge to prevent lap marks and lay off in the direction of the grain. Take care to not introduce bubbles.

This is a three coat flooring system. If the desired colour is achieved in less than three coats, complete the system with a Feast Watson Floorclear as per label instructions.

Stronger colour can be developed with further coats of Black JapanTM Floor Finish. Continue applying coats by the above procedure, sanding between coats, until the desired colour is achieved.


Regularly clean using Feast Watson Floorclean. Monitor the surface for signs of colour loss or surface defects. When floor requires an additional coat of Black JapanTM Floor Finish, apply as per the instructions for Previously Coated Surfaces
