Damp
Concrete -
situations where you need to seal a concrete floor: 1.
New concrete floor - where the moisture content is too high to safely lay
timber flooring, parquet flooring, underlay or carpet - typical in new build or
extensions. If the floor is not sealed dampness will build up under the flooring
leading to mould growth. Timber floors may expand, lift and buckle. 2.
Old concrete or slab floor - where you cannot be sure if a waterproof membrane
exists under the floor or where it may have been damaged. Old tiles or flooring
may have been lifted leaving old glue, asphalt or bitumen. 3.
Original Asphalt Floors - where the asphalt has cracked or dried out, allowing
moisture vapour to surface. 4.
Parquet, Wood Block Floors - where the bitumen adhesive has failed, causing
blocks to swell and lift.

Quick
Damp Test - no tools required Before
sealing a floor always check for water leaks (see below
). You can carry out a simple test on the concrete to see if moisture vapour
is coming up through the floor (rather than Condensation forming on the floor
due to high humidity in the room). Brush
the floor to remove dust. Take a square of clear plastic about 6 inches x 6 inches
(150mm x 150mm) and seal around the edges using plastic insulation tape. Leave
over night. The next day inspect the plastic for water droplets inside - if there
is moisture present you have a damp floor.
