5. They improve resistance to salt but not to aggressive corrosive
chemicals such as hydrochloric or sulfuric acid.
The success of monolithic surfacing installationsisvery much predicated
on the qualifications of the design, engineering, and installation personnel,
be they in-house or outside contractors.
The following fundamental rules arei mportantt ot he success of any
monolithic surfacing installation:
1. Substrate mustb ep roperly engineered to be structurally sound,
free of cracks, and properly slopedt odrains.
2. New as well as existing slabs must be clean and dry,freeoflaitance
and contaminants, with ac oarse surfacep rofile.
3. Ambients lab and materials to be installed should be 65–858 F
(18–298 C). Special catalyst and hardening systems area vailable
to accommodate higher or lower temperatures, if required.
4. Thoroughly primes ubstrate beforea pplying anym onolithic
surfacing. Follow manufacturer’s instructions.
5. Thoroughly mixindividualand combined components at amaximum
speed of 500 rpmtominimizeair entrainment during installation.
6. Uncuredm aterials must be protectedf romm oisturea nd
contamination.
Monolithic surfacings are unique, versatile materials used primarily as
flooring systems. They area vailable in av ariety of formulationst o
accommodatev ariousm ethods of application. They employ manyo ft he
installation methods that have been successfully utilizedi nt he Portland
cement concrete industry.T he most popular methods are:
1. Hand-troweled
2. Power-troweled
3. Spray
4. Pour-in-place/self-level
5. Broadcast
Hand-troweled applications are approximately 1/4 in.( 6mm) thick and
are suggestedf or small areas or areas with multiple obstructions such as
piers, curbs, column foundations,t renches, ands umps.T he finished
application is tight and dense,a nd it has ah igh-friction finish. Topcoat
sealers are recommended to provide increased density and imperviousness
with asmooth, easy-to-clean finish. High- and low-friction finishes are easily
accomplished predicated on end use requirements.
