Surface
Preparation: Typical for All Surfaces:
- Floor should be free of oils, waxes, curing compounds,
sealers and any foreign material.
- Clean floors with a mechanical scrubber with a vacuum pick
up or shot blasting equipment to remove dust and dirt. DO NOT broom sweep.
- Use hand metal scrubbers. Mop or wet dry vacuum in small
areas where a mechanical scrubber is impractical. Note: Refer to specific floor sections
below for further instructions.
New and Old Concrete Surfaces:
- Surface should be hard, dense and non-dusting.
- Surface should be twenty-eight days or older and free of all
curing agents, sealers etc.
- Patching materials that are loose or unsound should be
removed. Refer to "Special Surfaces" for further details.
- Test the Steel Services & Supplies Ameri Floor Prime* on
the prepared surface to insure good adhesion:
Step A: Apply the Steel Services & Supplies Ameri Floor Prime to a 4' by 4'
(1.22 m x 1.22 m) area with broom or mop and allow it to dry.
Step B: Using the pointed end of a knife or a sharp device, scrape through the
Steel Services & Supplies Ameri Floor Prime. If the Ameri Floor Prime can be peeled
up, it is not a suitable application. If the scraper only scratches the Ameri Floor Prime,
the surface is suitable for application.
Old Concrete Surfaces with Cut back:
- Refer to the general procedures for "New and Old
Concrete".
- Areas with heavy or loose cut-back must be removed.
- Shot blasting is recommended.
- Use Steel Services & Supplies Ameri Orange peel to
remove any residual cut-back.
Tile and Terrazzo Surfaces:
- Must be free of all waxes, oils, sealers, or grease and any
loose or foreign material.
- The Steel Services & Supplies Ameri Floor Prime test is
critical. Refer to the Steel Services & Supplies Ameri Floor Prime instructions in
"New and Old Concrete".
Wood Floor and Wood Floors With Cut-back Surfaces:
- Refer to the general procedures for "New and Old
Concrete" steps 1-4
- The construction of the floor should be sufficient for the
intended loading and use without any flexing or moving.
- Because concrete and wood have very different expansion
movement characteristics it is recommended that reinforcing such as hardware cloth be used
and attached with staples on a minimum of 12" (30.5 cm) centers.
- Steel Services & Supplies Ameri Prime can be applied
before or after the installation of wire.
Wear Surface: Steel Services & Supplies Ameri Floor SL
can be used as an interior wearing surface for foot traffic when coated with an
appropriate Steel Services & Supplies Sealer. Please consult Steel Services &
Supplies for specific recommendations for your application.
Shot Blasted or Standard Surface:
- Refer to the general procedures for "New and Old
Concrete" steps 1-4.
- These surfaces can be very dusty requiring extra care in
removing dust.
- Because these surfaces are more porous, extra Steel Services
& Supplies Ameri Floor Prime will be required.
- At least patch should be applied to determine if surface is
properly primed and sealed. Numerous pinholes appearing either during or after placing the
primer indicates the floor is not adequately primed and sealed.
Special Surfaces: Special surfaces require special
procedures and should be referred to the manufacturer's representative. Special surfaces
such as: Gypsum, latex cement, lightweight concrete, ceramic tile and vinyl tile.
*Primer Application: Steel Services & Supplies Ameri
Prime, a special adhesive agent made especially for Steel Services & Supplies Ameri
Floor SL, is critical to the installation of Steel Services & Supplies Ameri Floor SL.
The purpose of Steel Services & Supplies Ameri Floor Prime is to seal the surfaces
which otherwise absorb water from the material and do not allow proper hydration or
provide a suitable surface for adhesion or Steel Services & Supplies Ameri Floor SL.
- The Steel Services & Supplies Ameri Floor Prime comes
ready-to-use. Coverage is 100-300 square ft. per gallon (2.5-7.4 m²/L) depending on the
porosity of the surface.
- Apply with a mop or broom. Drying time is 2-3 hours at
75°F(23.9°C) but slightly longer with a decrease in temperatures and slightly less with
an increase in temperatures. Steel Services & Supplies Ameri Floor Prime will remain
slightly tacky when dry. NOTE: Poor ventilation will delay normal drying time. Fans will
help increase circulation to increase drying time.
- Any Steel Services & Supplies Ameri Floor Prime puddled
in low areas should be wiped up.
- Primed surfaces are good for 24 hours providing it is not
subjected to traffic. If the placing of the leveler exceeds 48 hours or there has been
traffic across the floor a reapplication of primer is necessary.
- Very porous surfaces require at least two applications of
Steel Services & Supplies Ameri Floor Prime. The first application may be diluted at a
ratio of 1:1 with water and the second coat at full strength.
- It is recommended that in all cases a primer test be
performed prior to placing Steel Services & Supplies Ameri Floor SL. Refer to the
"New and Old Concrete" instructions.
Materiel Installation - hand Equipment Required:
- 1/2" (1.27 cm) electric drill 6.50 r.p.m.
- Marked container for measuring water.
- Mixing container size: minimum 5 gal. pail (18.9 L) a 15 gal
pail (56.7 L) is recommended.
- Mixing Paddle: wire or egg beater type.
Mixing: Place pre-measured water into mixing container.
Start drill and ass Steel Services & Supplies Ameri Floor SL slowly but DO NOT exceed
two to three minutes. Water may be adjusted slightly to procedure desired consistency.
CAUTION: Excessive water will cause segregation and cracking, reducing compressive
strength resulting in bond failure.
Water Requirements: Interior 45 lb. Steel Services &
Supplies Ameri Floor SL (1 bag) (20.4 kg) 9.5 -10.5 pints of water (4.5-4.9 L)
NOTE: The data shown is based on controlled laboratory
testing. Reasonable variation from results shown can be expected. Field and laboratory
testing should be controlled on the basis of the desired placing consistency, rather than
strictly on the water content.
Placing: It is recommended that placing should be in lanes
15' (4.6 m) in width formed using foam tape or other suitable forming material. Place in a
continuous operation by pouring back and forth within the width of the formed area. It is
important that this be done in a continuos operation to achieve proper merging of the
material. DO NOT exceed 2-3 minutes in placing material. Crew sizes, equipment and
material should be of such a size to continuously place in 2-3 minutes.
Pimping: There are carious type of pumps manufactured and
available for the application of Steel Services & Supplies Ameri Floor SL. Consult
with your local representative for their names, availability and recommendations.
