Sempatap 5mm Insulation

• EASY AND QUICK TO INSTAL
• ELIMATES MOULD PROBLEMS
• MAKES ROOMS WARMER IMMEDIATELY
• STOPS HEALTH RISK
• REDUCES CONDENSATION
• EXCELLENT SOUND ABOPTION

Sempatap is thermal insulation on a roll as simple and easy as wallpaper to apply and is the economical solution for resolving condensation problems and reducing heat loss.  It has been specified and successfully used by Local Authorities, Housing Associations, private landlords and homeowners throughout the UK and Europe for over 30 years.

Condensation and mould:

Condensation and black mould complaints are problems faced by maintenance and housing managers throughout the UK.  SEMPATAP is a quick and easy to apply remedy which alleviates condensation problems and makes cold, damp rooms immediately warmer.  When applied to wall or ceiling surfaces SEMPATAP dramatically reduces the “u” value – which, in turn, reciprocally raises the room temperature.  It provides a surface on which condensation will not form and is excellent for use on cold solid walls, concrete ceilings, cantilever beams, cold bridges, ring beams etc.  Mould in houses, even in a small contamination, is a serious health risk which can result in asthma, upper respiratory diseases and food poisoning.  Furthermore, several independent reports confirm that mould spores are detrimental to the wellbeing of adults and children and, as such, are classified as a statutory nuisance.

Sound properties:

SEMPATAP has very good sound absorption properties and is particularly effective in the range of unpleasant high frequencies.  SEMPATAP is particularly useful in helping to overcome problems of reverberation and sound transmittance between neighbouring flats or in high and low rise blocks of flats.

Sempatap insulation:

SEMPATAP is made from a natural material – latex – with a durable woven fibre-glass face.  It is in an open and closed cellular construction, which allows the substrate to breathe.  It is very easy to apply and operatives do not need any special skills or tools – SEMPATAP rolls are 1 metre wide and 12.5 metres long, therefore it is just like wallpaper – you can get five drops out of a roll.  The adhesive is water-based, therefore there are no nasty smells and work can be undertaken with tenants in situ – it is not necessary to vacate the property.  It can be decorated with virtually anything – emulsion, wallpaper, even tiled and redecoration presents no problems – the fibre-glass finish allows the removal of old wallpaper via any method without damage to the SEMPATAP.  Using SEMPATAP in conjunction with MGC’s proven mould eradication treatments eliminates black mould problems, dramatically reduces condensation and provides warmer, healthier living conditions.

How to Apply Sempatap 5mm Insulation

Mould growth on walls and ceilings to be treated in accordance with MGC specification for the eradication of mould.  Mould infected surfaces must be sterilized with RLT BACTDET 05.  Dilute at 1:4 with warm water and apply by brush, cloth or sponge, extending treatment one metre beyond visible signs of infection.  Wallpapered surfaces must be washed down with RLT BACTDET 05 solution prior to stripping.  Bag up wallpaper, seal and remove from the premises immediately.  Wash infected area again with RLT BACTDET 05 solution and allow to dry before proceeding.  Apply by brush one coat of RLT HALOPHEN diluted at 1:4 with water to previously mould infected areas, extending treatment one metre beyond visible signs of contamination.

Surface Preparation

 Existing wallpaper should be removed, Artex ceilings should be de-nibed to remove all high peaks.  Fill all large cracks, holes etc using a good quality filler.  Remove all flaking paint, gloss painted walls to be lightly abraded wet to key the surface and washed with sugar soap then rinsed clear.  All highly porous surfaces, chalking substrates and Artex ceilings to be primed with one coat of SEMPATAP ‘A’ PRIMER and allowed to dry.  Prior to application of SEMPATAP ensure that all surfaces are firm, dry and free from mould.

Cut SEMPATAP to length, allowing 25mm overlap at each end.

Roll-up cut length of SEMPATAP with foam facing out.

Apply SEMPATAP ADHESIVE with serrated MGC ADHESIVE SPREADER, suitable notched trowel or medium pile roller.  Only apply adhesive to one drop length area at a time.

Hold the roll-up piece of SEMPATAP in one hand and unroll the first half metre, (keep remainder rolled-up), and apply foam side to the wet adhesive.  Keep the roll on the wet adhesive.  Unroll another half metre.  Using light hand pressure, smooth out the unrolled piece that is in contact with adhesive.  If light pressure is used, SEMPATAP can at this point be repositioned by sliding into place.

When SEMPATAP is in the required position, use the SEMPATAP SPATULA to firm up.  The remainder can then be unrolled down the wet adhesive and smoothed out with the same tool removing any entrapped air bubbles. Firmly push SEMPATAP into sharp internal angles – ceiling line, skirtings etc with SEMPATAP SPATULA.  Trim the top and bottom edges using a sharp bladed knife.  (The type of knife with a snap-off blade is ideal). Apply subsequent pieces as above but leave a narrow gap between each piece.  The gap should be approximately 1-2mm. Complete the application of SEMPATAP to the area being treated.

SEMPATAP can be decorated with virtually any finish – wallpaper, emulsion, even tiles.  For a perfect finish when using emulsion, cross line with lining paper to totally hide the joints.

EMULSION – Apply two coats of BIOCHECK Matt or Silk Emulsion by brush or roller at a coverage of approximately 12 square metres per litre, per coat.  The first coat may be diluted with 10% clean water.  It is recommended that SILK is used in kitchens and bathrooms.

WALLPAPER FINISH – To hang wallcoverings (including lining papers and woodchip), seal the surface of the SEMPATAP by applying a coat of PVA primer or SEMPATAP ‘A’ PRIMER and allow to dry thoroughly.  Read fully and carefully follow the wallcovering manufacturers instructions.  Use the recommended wallpaper paste/adhesive made up in accordance with the manufacturers instructions.

Add two MGC FUNGICIDAL ADDITIVES per five litres of paste or size and mix well in for all wall papering.  For embossed and woodchip papers apply two coats of BIOCHECK Matt or Silk Emulsion.
