Chestnut Plank Flooring Restoration – Ministry of Justice
San Bernardo building · Central Madrid · Chestnut plank floor over a historic floor structure

Work performed
Full restoration of the chestnut plank floor at the Ministry of Justice. The historic building is on Calle San Bernardo in Madrid.
Characteristics of the base
The floorboards rest on timber battens over an old floor structure. Iberian chestnut gives good dimensional stability through Madrid’s humidity swings.
Technical intervention and finish
We fastened the boards to the battens with concealed fixings. Sanding with cyclonic dust extraction removed the dark varnish while taking off as little wood as possible. We applied an isolating, tannin-blocking primer and three coats of heavy-duty 2K waterborne varnish with a reaction-to-fire classification from the manufacturer.
