Uses
AD-FLOOR EXTERIOR is an ideal underlay for levelling most common
internal subfloor prior to the installation of floor coverings such as
ceramic floor tiles, carpet, vinyl and wood flooring (minimum
levelling thickness 5mm). Suitable for use with underfloor heating.
It also contains powdered latex eliminating the need for separate
expensive latex liquids. Durable and hard wearing and can be used
to patch repair rough concrete in domestic situations subject to
foot traffic and light wheeled traffic. Ideal for use on domestic
garage floors as a final wear coat or can
be overpainted with Bond It ALKYD
FLOOR PAINT.
Substrates
May be used over:
- Concrete and cement based substrates.
- Calcium sulphate (gypsum) screeds
(sanded and vacuumed).
- Properly prepared old Ceramic tiles, natural stone, terrazzo.
- Properly prepared old water resistant adhesive residues.
- New mastic asphalt screeds must be flooring grade (IC10, IC15)
with layer thickness 3-5mm.

Preparation
Sub-floors should be clean, dry, structurally sound and free from
grease, oil, paint, polish or other contaminants that may hinder
adhesion. Any adhesive or paint residues must be mechanically
removed back to a sound base, likewise all friable areas must be
removed and the substrate repaired with a suitable repair
compound as required. It is essential that ambient conditions do
not exceed 55% relative humidity for at least 28 days after
application. Increased levels of humidity can lead to product
failure.
• All sub-floors on or below ground level should have an effective
damp proof membrane and for subsequent laying of flexible
floorcoverings or timber should have a moisture content of 75%
RH or below. For moisture levels above 75% RH, a surface damp
proof membrane should be applied. Contact Technical Services.
• Gypsum and Anhydrite screeds should always be free from
moisture. Do not use surface damp proof membranes on gypsum
substrates as a method of controlling moisture content.
• Old ceramic tiles should be thoroughly cleaned and abraded.
• Old water-soluble adhesives, should be removed completely
and the surface then primed with a waterproof primer such as
PRIMER AND FLEXIBLE ADMIXTURE.
• Old water-resistant adhesives should be mechanically removed
as far as possible and remaining residue firmly bonded.
Vacuum clean the surface before application of waterproof primer.
ABSORBENT SURFACES such as concrete and cement should be
primed with a waterproof primer such as Bond It
PRIMER AND FLEXIBLE ADMIXTURE. Note: PVA is not
suitable for priming prior to application of AD-FLOOR
EXTERIOR.
NON-ABSORBENT SURFACES should be cleaned and
primed with a suitable primer. Bond It EXTERIOR
PREGRIT is also recommended for this purpose.
• Ceramic should be clean and free from grease
before priming.
• Water resistant adhesive residues should be removed as far as
possible before priming.
• New sanded mastic asphalt should be vacuumed before
priming. Recommended layer thickness over mastic asphalt is
maximum 3-4mm.
• Wooden floors should be over boarded with 15mm exterior
grade plywood rigidly fixed with screws at 300mm centres. Prime
as for absorbent surfaces.
• Calcium Sulphate / gypsum screeds should be sanded and
vacuumed before priming with 2 coats of Bond It PRIMER AND
FLEXIBLE ADMIXTURE and left to dry for 24
hours. If AD-FLOOR EXTERIOR is to be used at
thicknesses above 10mm over a gypsum
screed (contact Technical Services). Note: Not
suitable for use over old mastic screeds.

Mixing
Use 3.6L of clean water for every 20Kg bag of
LevelMaster AD-FLOOR EXTERIOR. Slowly add
the powder to the water whilst stirring with a
suitable heavy duty slow speed drill or
paddle. Stir for approximately 3 minutes until
a homogenous lump free mix is formed. Do
not overwater! Foam while mixing, or settling
of the sand aggregate while placing, indicates
over-watering.

Application
Pour the AD-FLOOR EXTERIOR onto the
prepared surface and trowel to a smooth
finish. Even surfaces can be obtained using a
pin leveller and in higher thicknesses a spiked
roller is recommended, Do not mix more than
can be laid in 20 minutes. Never add extra
water to this product once it has started to
set. For higher layer thicknesses (above 3mm)
contact with vertical surfaces should be
avoided by using edging strip. Edge, interior
and movement joints in the floor should not
be covered by AD-FLOOR EXTERIOR and should
be closed with suitable measures. Do not use
at temperatures below 5˚C. LevelMaster ADFLOOR EXTERIOR will accept light foot traffic
after approx 4 hours.

Ready For Covering
• 3 to 10mm thickness of AD-FLOOR EXTERIOR
can be covered with FLEXIBLE floor coverings
after approx. 24 hours.
• Up to 50mm thickness over internal
concrete and be covered with CERAMIC TILES
after approx 4 hours.
• For non porous surfaces the following
drying times are recommended before
application of CERAMIC TILES:
• Up to 10mm – 1 day
• 10-20mm approx. 3 days
• 20-30mm approx. 7 days
• 30-40mm approx. 10 days
• 40-50mm approx. 14 days.

Coverage
One 20Kg bag is sufficient to cover
approximately 4m2 at a thickness of 3mm.

Cleaning
All tools and equipment should be cleaned in
water. Cured material can only be removed
by mechanical means.
