Existing Solid Floors:
Parquet blocks can be laid on numerous solid substrates such as
concrete, dry
screed, self-levelling compound or flooring grade ply wood or
chipboard, but never
directly onto floor-boards.
All substrates must be structurally sound, flat and dry.
All new screed or concrete
must be completely dry – allow at least1 month for every inch
depth of new
concrete. !isting screeds"concrete must be checked for
moisture– this can easily
be done by hiring a specialist meter #hygrometer$.
A reading equal to or greater than %&mc by volume
indicates that a suitable damp-
proof membrane must always be installed – either a ' coat"' part
liquid layer #e.g.
(ewmar or )ika$ or a properly installed non-permeable layer
#make sure the ends of
the plastic are continued up into the walls to fully protect the
wooden floor$.
*f the screed is between '-%&mc it may be advisable to use
one coat of the liquid
+P as a moisture barrier.
he only way of fi!ing block flooring is to glue the blocks to a
solid surface.
ou do not need to use a fle!ible adhesive when gluing blocks as
they tend to be
small pieces of wood and therefore any e!pansion or contraction
is at a minimum.
he rigid adhesive recommended is Lecol 5500. *f you are
installing new larger
continental-style blocks it would be better to use a fle!ible
adhesive such
as Sikabond T5.
!"#" /% adhesive cannot be used with old blocks which still have
bitumen glue on
them.
)anding must be carried out carefully and methodically to avoid
unsightly scores or
ridges.
he best finishes to protect a hardwood floor are either a water
based lacquer or ahardwa! oil.
