AdhesiveAltro TrowelEasy 19 Plus is the only recommended
adhesive. Altro only approves the adhesives
recommended here; always follow detailed
application and usage instructions on data
sheet or as supplied with the adhesive. For more
detailed information please see page 5.
GroovingA 3mm groove must be cut evenly along each
floor joint (except internal/external mitres) using
a hand or automatic rotary grooving tool. Use of
the special Altro automatic grooving blades is
recommended as standard blades are quickly
destroyed when used on safety flooring.
Forming a hot welded jointAfter cutting in and adhering the sheet vinyl
flooring, all joints must be hot welded with Altro
Weldrod™, using a hot air welding gun fitted
with a 5mm high speed welding nozzle. Internal
and external mitres should be hot welded. After
a long period of use, the filter of the welding
gun may become clogged with debris. This
must be kept clear to reach the optimum weld
temperature. Where possible, allow 12 hours
between laying and welding, to ensure the
adhesive is properly set.
WeldingThe internal and external mitres on the coved
sections should be welded first. Turn the speed
nozzle at the end of the welding gun to the up
position for easier starting. Once the mitres are
finished, turn the nozzle to the down position to
hot weld the grooved floor joints.
FinishingOnce the weld has cooled and set, trim the weld
with the most appropriate tool such as a spatula
fitted with a spatula guide or sledge. Then, using
the spatula only, trim the weld flush with the surface
of the flooring material. For external mitres use the
square router blade and for internal mitres the
round router blade. For details on equipment and
tools, refer to Altro’s Recommended Equipment
and Tools data sheet.

Seam Grooving
• All seams in Altro Safety Flooring must be
grooved prior to heat welding.
A 3mm wide groove must be cut evenly
along each joint.
• Due to the metal particles and quartz
crystals in the Altro Flooring, do not use standard hand or electric grooving tools. Fit a diamond- cutting blade to
electric grooving tool if required for use.
Eye protection should be worn.
• Do not attempt to groove seams in
Altro Flooring until the adhesive has set.
Minimum 24 hours.
• Do not attempt to groove seams by ‘free hand’. Always use a straight edge as a
guide.
• Seam grooving by hand shall be
accomplished using the Altro grooving tool and the grooving blade. One
grooving blade with 4 cutting edges will
groove approximately 20 l/m. Change
grooving blades regularly.
• Align centre of grooving blade to exact
centre in Altro Flooring seam.
Grooving tool shall be held at the
correct angle (of approximately 45°)
to ensure optimum cutting of required
groove.
• The Altro hand groover must be used
by pulling along the centre of the seam
guided by the straight edge.
• The depth of the groove shall be to a
minimum of ½ to maximum of 2/3 of the thickness of the Altro Flooring.
Transition with Clamping Drain
For locations where the drainage of liquid spillages from floors is a necessity and a watertight seal must be formed with the drain. For clamping ring type gullies* which have been installed in accordance with the manufacturer’s instructions. The sheet vinyl flooring must be dressed down and adhered with a water resistant adhesive into the drain outlet and be secured by the clamping ring. *For example those manufactured by Wade International, Tel 01787 475151; Fax 01787 475579; e-mail [email protected].

Did you know?
Altro safety flooring can be
installed over wood and
many other types of flexible
subfloor including metal walk-
in coolers, whereas ceramic
tiles would crack or debond
Altro: the modern alternative to tiles
With the range of colour from Altro Whiterock White and Altro Whiterock Satins, you can have the colour range choices that tiles provide, without the worry of contamination.
As a result, businesses can enjoy reduced long-term maintenance costs, with a significantly reduced risk of contamination or, should the worst happen – an incidence of food poisoning occur – possible litigation or even closure. All this makes it perfect for use in any catering area.
Altro Whiterock can even be installed over existing tiles

Transition with other floor surfaces
For locations where sheet vinyl flooring must be
finished to another floor surface with a water
tight seal. A Visedge VR vinyl securing strip*
should be installed along the transition. The sheet
vinyl flooring is fixed down then cut in, grooved
and hot welded to the PVC insert within the
Visedge system.

Properties
TrowelEasy Plus is a solvent and water-free,
two-part polyurethane adhesive supplied in the
correct quantities for mixing. Both A and B parts
are held within the container.
Supplied in 3kg, and 6kg units.
Subfloors and site conditions - must conform
with AS 1884-2012
TrowEleasy Plus can be used on dry, dust-free
subfloors such as sand/cement, granolite,
plywood, chipboard, hardboard, metal and
epoxy surfaces, damp- proof membranes and
power float concrete. It is important that the
subfloor is as smooth as possible, any undulation
may cause pockets of adhesive to form bubbles
in the floor covering.
Mixing of parts A and B
Part A is a viscous paste. Part B is a fluid
liquid supplied in silver foil sachets. Stir part A
thoroughly. Transfer part B into large container
holding part A and mix thoroughly until a
uniform consistency is obtained throughout.
A drill with a paddle attachment should be
used to ensure complete mixing. Scrape sides
thoroughly during this process. Care should be
taken to avoid spillage when mixing, as staining
of the floor surface may occur.
Application
Apply adhesive to subfloor only, as soon as
possible before adhesive thickens (within 15-20
minutes of mixing, depending on temperature).
Spread evenly with a notched trowel. It is
important to use a small notched trowel to avoid
entrapment of air between the floor covering
and subfloor. Place covering into wet adhesive,
do not roll, and expel all trapped air with the use
of a flat wooden or Perspex trowel, wrapped in a
soft textile material which has been pre-wetted.
Limit trafficking of the floorcovering when the
adhesive is still fresh. If any corners, joints or edges
are lifting while the adhesive is setting, these must
be weighted. Leave weight undisturbed and the
floor covering traffic free until the adhesive has
set. Where this procedure is not followed, special
care should be taken to check all joints etc,
before leaving site for the day.
Health & safety
TrowelEasy Plus component B is hazardous if
inhaled. It also may irritate the skin, the eyes
and the respiratory apparatus, and may cause
allergic reactions in those subjects predisposed.
While preparing and applying the product, we
recommend protecting the throat and lungs, and
the use of protective gloves and goggles.

Apply the product in well-ventilated areas. In the
case of accidents, or a feeling of nausea, seek
medical attention.
