5.4 Subfloor Surfaces
5.4.1 Wood and Wood like floors
Pound down or remove any nails or metal obstruction to avoid blade
damage.
Glued hard wood flooring
A 25 cm blade is recommended for regular adhesive, a 15 cm blade
for epoxy.
For proper removal of hardwood flooring (plank solid, plank laminated,
parkay, parquetry laminated)flooring must be scored to blade width.
This is done by using a circular saw set at a depth of 99% of the
thickness of the board, just missing the subfloor surface when on concrete
A chalk line for scoring lines can be used across the floor the width of
the blade
See figure 5.4 - A and 5.4 - B
True parkay flooring scoring is not necessary.
It will come up in small pieces.
When working over plywood sub-flooring, try to run machine in the same
direction
as
the grain in the wood. Blade in most cases bevel down.
On solid wood floors like plank, run in the same direction as the plank, not cross grain
or cross plank.
Removing the front counterweight will help on all soft surfaces.
5.4.2 Concrete
When working on concrete slab, normal blade position is bevel up for best performance,
especially when cleaning adhesive. On occasion, bevel down gives better
blade life.
5.4.3 Gibcrete and Soft Poured Flooring
Usually require blade level down to create a better wearing surface, although bevel
up may work if front counterweight is removed.
Beware of expansion joints and floor mounted receptacles or other obstacles
in the floor.
