Floor,
previously treated with PV67, where the finish
is in good conditions only need to be sanded
lightly before the application of Sadolin
PV67 as long as the surface is free from gease,
polish etc.
If the previous floor finish contains
wax, has been damaged or is very uneven
the floor should be sanded back to bare
wood. All resinous wood has to be treated
immediately after sanding to bare wood.
Pine wood with a large amount of heartwood
has to be sealed with Sadolin PV67 Sealer
to avoid a reddish tinge.
If Sadolin PV67 is applied on stained
floor, please make sure that the stains
sre solvent based and have dried properly,
normally for 3-5 days.
