A) Composition
Dex-O-Tex Neotex-261 is a troweled, jointless floor. It is a water-phase
resin material which is applied in a series of coats to achieve a smooth
finish. It can also form an integral, sanitary coved base. Dex-O-Tex Neotex-261
is resistant to a wide range of acids, solvents and food fats (contact
Crossfield Products Corp. for separate chemical resistance tables). In
itself, the material is waterproof but for positive protection against
leakage due to cracking of the surface over which Dex-O-Tex is applied,
a Dex-O-Tex Waterproof Membrane should be specified (see pertinent Dex-O-Tex
Product Description Sheets). Dex-O-Tex Neotex-261 can be installed over
concrete, metal or wood surfaces (consult Crossfield Products Corp. for
detailed specifications for wood surfaces).
Thickness of Dex-O-Tex Neotex-261 is approximately 1/4" (6.35 mm). See
Dex-O-Tex Color Chart for colors. Final finish of Dex-O-Tex is available
in choice of several gradations of slip-resistance.
As compared to epoxy flooring materials, Dex-O-Tex Neotex-261 is virtually
unaffected by moisture vapor transmission coming upwards through concrete
floors.
B) Typical Uses
Floors for animal housing, many industrial uses, television studios,
institutional service, lockers, toilet and shower rooms – in general, areas
where sanitation, waterproofness and chemical resistance are important.
C) Advantages – Limitations
Advantages
1. Monolithic, including integral base where specified.
2. Resistant to many chemicals.
3. Can be installed over wide range of new and existing surfaces with
excellent adhesion.
4. No toxic odors during installation.
5. Low burning rate and negligible smoke production.
6. Waterproof – in conjunction with Dex-O-Tex Membrane.
7. Installed only by Qualified Dex-O-Tex Contractors – factory trained
and approved.
Limitations
1. Not designed for constant heavy steel-wheeled trucking.
2. If sub-surface cracks, Dex-O-Tex Neotex may reflect cracks to some
degree.

D) Trowel apply 1/4" body coat
E) Apply two grout coats to fill in and smooth off body coat.
F) Power sand to remove trowel marks.
G) Roller apply two coats of saturating final-finish dressing in texture
as selected.
Note: Special Dex-O-Tex Drains, Floor Cleanouts, etc., are available
from most major drain manufacturers. These should be used in conjunction
with Dex-O-Tex Neotex. Consult Crossfield Products Corp. for current listing
and plumbing roughings.
Crossfield Products Corp. maintains offices and/or factories at all
addresses listed above. Qualified Dex-O-Tex Contractors are established
in all major trading areas in the United States, Canada and various European
and Far Eastern nations.
After period of sustained abrasive wear, floor may require a repeat
maintenance roller coat of final-finish dressing.
Consult Crossfield Products Corp. for specification assistance, detailing,
etc. This consultation is highly recommended prior to specification.
