Floor Coating - to create a vapour proof membrane

 

Damp Concrete - 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.

Easy to apply by Brush or Roller


Quick Test

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.

Epoxy Based - Ultra Epoxy Seal Coat has high chemical resistance, is a full vapour barrier, is easy to apply over smooth renders, screeds or 'tanking' layers.

Epoxy Paint Coloured Coatings are also available - grey and red in stock, other colours to order.

Apply one or two coats to ground floors, two coats to below ground floors.


Ensure that you seal the floor to wall joint before applying the coating.

This can be sealed using Structural Epoxy Pouring Resin or our Fillet Seal or BondAcryl mixed with sand and cement.

Ultra Epoxy Coating - available in 500cc, 2.5 and 5 litre containers, supplied as 2 liquids which have to be mixed together.

Available in Clear from stock.

Standard colours available - grey and red - others to Order.

Testing to find the water source

A. Ask your local water Authority to test your Water Mains pipe for leaks. Particularly ask them to test your neighbour's supplies on both sides: if you live on a hill with properties above you check all those on the high side of your house. This service should be free of charge.

B. If you have liquid water in your building (on a solid floor, or in a basement) ask the Water Authority for an analysis - this will tell you where the water comes from - mains, sewerage or spring/ground water.

C. Test your own drains - test the foul water by finding the man hole cover, lifting it and running a tap to see which hole your water flows from. Block this hole with a rubber bung (Hire Shop or Builders Merchant - 4 inch or 6 inch). Then fill up a sink or loo with water and mark the level. Leave over night - if not at the same level next day you need a Drains Company with a camera to investigate. Don't forget to remove the bung!

D. Test the surface water drains - place a Dye Bag or granules of drains testing dye (Builders Merchant) into the drain and fill up with water. Using a torch, at night, look for signs of the coloured dye - it glows in the dark.
