4mm Sempafloor is made from a natural latex, with a non-woven polyester surface which provides an ideal finish for the application of all types of floor covering including carpet vinyl, wood panel and tiles. Sempafloor is flexible and provides excellent indentation recovery which allows it to be used in the heaviest of traffic areas. Sempafloor will not deteriorate or crumble and is very hard wearing and resilient to point loading. It is is supplied in rolls 12.5 long and 1 metre wide. Floor surfaces require minimal preparation, and, in most circumstances, it is not necessary to remove skirting. It can be used as either thermal insulation for cold surfaces or as acoustic insulation where impact noise is a problem.
CHARACTERISTICS
- Simple and easy to install,
- Warms floors,
- Reduces condensation problems and mould growth,
- Excellent sound absorption,
- Overcomes the problem of foam backed carpets sweating up against concrete floors,
- Reduces heat loss,
- Saves money.
- Thermal insulation for cold surfaces,
- Acoustic insulation where impact noise is a problem,
- Where cold bridging is the cause of condensation and mould growth on concrete floors, solid floors,
- Ideal for use on rooms over garages or driveways, rooms over external passageways, park home floors and rooms over cellars/basements.
- Ensure floor surface is firm, dry, free from dust, mould, grease and all other contaminants.
- Screw down loose, squeaking floor boards.
- Uneven timber floors should be boarded out with 5-6mm ply prior to the installation.
- Mould contaminated surfaces must be sterilised using RLT Bactadet 05. Dilute at 1:4 with warm water and apply by brush, cloth or sponge to remove mould.
- Allow surfaces to dry thoroughly.
- Highly absorbent surfaces (concrete, etc) will require priming with one coat of Sempatap A Primer. Apply one coat by brush and allow to dry before proceeding.
- Fill any large gaps, cracks and holes in concrete floors.
- If Sempafloor is used as acoustic insulation remove all skirting to allow for upstand behind the skirting.
- Cut Sempafloor to length, allowing appropriate overlap at each end and around the perimeter of the room. (For thermal use allow 25mm excess.)
- Roll-up cut length of Sempafloor with foam facing out.
- Apply one coat of Sempatap Adhesive with Sempatap Adhesive Spreader, notched trowel or medium pile roller to an area not more than 5-6 square metres, 1 metre width.
- Unroll first metre of Sempafloor (keep remainder rolled-up), and apply foam side to wet adhesive. Smooth out using Sempatap Spatula. Tuck Sempafloor into wall or floor junction and under skirting.
- Roll out remainder of Sempafloor and ensure it is smoothed out with the spatula and firmly positioned.
- Butt join subsequent lengths of roll and continue application until the entire floor is covered.
- Trim surplus using a sharp-bladed knife.
- If before the application of the final floor finish there is to be a covering of plywood or similar material, the overlap should be cut away after the application of such materials. Ensure boards are applied cross lined to the direction of Sempafloor.
- Cover with chosen floor finish.
