Kemseal P14-Fibre is a liquid applied polyurethane
modified copolymer waterproofing membrane containing a fibrous filament
reinforcing. When fully cured, Kemseal P14-Fibre forms a Class III flexible
waterproof lining to showers and wet areas as described in AS 4858- 2004. Waterproofing Wet Areas within Residential
buildings. Kemseal P14-Fibre may be applied to most building materials
including reinforced concrete, cement render, wet area plasterboard, compressed
fibre-cement sheeting, plywood and particleboard wet area flooring. USE AREAS:
Shower Recesses. Wet Areas. Flashings. Balconies and Decks. Exposed Roof. Walls
Seamless- no joints or cracks.
User Friendly- water-based.
Balconies and Decks
COVERAGE: 1.5 Litres/ m2
SHELF LIFE: 12 months.
TOUCH DRY: 4-24 hrs +/-
depending on temperature.
COLOUR: Grey or Green.
RECOAT: 4-24 hours
SOLVENT RESISTANCE: Not Resistant
WEATHER RESISTANCE: UV stable - may be top coated with
Kemseal AC or other compatible waterbased coating. TILING: Kemforte P14-Fibre
may be tiled over when fully cured with a compatible one or two-part cement
based adhesive. Externally, provide sufficient measures for full allowance of
expansion and contraction in overlaying tiles and topping – particularly
important with sheet flooring externally, or damage to the membrane may occur
SURFACE PREPARATION: Ensure surface is firmly
placed/fixed to manufacturers directions. Surface must be free of dirt, dust,
loose particles, oil, contaminates, curing compounds and flaking concrete etc.
Acid etch if necessary. Concrete must be a minimum strength of 20 mpa and have
cured a minimum of 28 days. Surface must be dry.
Kemseal P14-Fibre is often self-priming when used on
internal surfaces eg. villaboard, chipboard, sound concrete, block work.
Absorbent surfaces may require priming with Kemseal P14 thinned with 20 - 50%
water or with Kemseal WBE applied at 6 m2/Litre. Prime damp areas and areas
subject to rising damp with Kemseal WBE. Plastic/Plumbing fittings shall be
etched and primed with Kemseal WBE. Allow to fully cure prior to membrane
Install leak control flanges around all pipe
penetrations. Fill all screw holes, cracks and voids with neutral cure
silicone. To all corners such as wall/floor, floor/hob, hob/wall junctions,
apply 12mm min cove of silicone sealant as a bond breaker. Apply sealant to
internal wall/wall joints to 1.8m above the shower tray, around tap flanges and
other discontinuities. Where angles are installed such as across bathroom
doorways or under shower screens (hobless shower) angle is to be firmly adhered
into a bead of sealant. Around pipe penetrations and floor waste outlets, apply
membrane to 1.5mm thick reinforced with polyester fabric 100mm wide across
REINFORCEMENT / BONDBREAKERS: A reinforcing fabric and/or
bondbreaker tape, should be used as necessary over the following areas:
Expansion joints, cracks, footing/floor to wall junctions, shower tray and hob,
joints in sheet flooring, vertical corners above shower tray, around floor/wall
penetrations, down into floor waste pipes and any other area where movement
will occur. Apply a bond breaking tape (eg 50mm PVC duct tape) over joints in
sheet flooring, or 1.5 mm x 20mm wide silicone sealant. Reinforcement may also
be required over voids in off form concrete. Reinforcement shall be laid into
the wet base coat and immediately over coated and worked in carefully to fully
saturate fabric. Refer to Kemforte for full specification on expansion joints.
APPLICATION: To the prepared surface, apply Kemseal
P14-Fibre by brush or roller in one or more coats to achieve a minimum dry film
thickness of 1.2mm. This will require min.1.5L/m2 . Turn membrane up at walls
and penetrations and down into drainage outlets. When dry, check for pinholes
or misses and rectify if necessary. Re-coat when dry. If membrane becomes dirty
or wet between coats, thoroughly clean or re-prime clean to ensure inter-coat
adhesion. Allow to fully cure before covering- generally 2-4 days.
PRECAUTIONS: Do not use Kemseal P15-Fibre
membrane in any situation beyond its physical limitations. Do not apply above
42oC or below 8oC ambient temperature. Wash equipment with water before dry. Do
not fix tiles until fully dry. Protect membrane against damage before and
during backfilling, tiling or covering. Where used externally, Kemseal 14-Fibre
may be top coating with Kemseal AC or covered with tiles, sand-cement topping
or soil etc. When tiled over externally, provide slip sheet of polyethylene
plastic sheet over membrane prior to sand-cement topping, in a manner to allow
for expansion and contraction of overlaying topping.
