Installation
Preparation
Concrete subfloors must be fully cured, moisture free and have no efflorescence. The
substrate surface shall be clean, dust and contaminant free. Cracks should be filled with
a crack filler or an elastomeric compound. Plumbing or electrical penetrations should be
packed with insulation and sealed.
Priming
To promote proper hydration and to ensure a solid bond, the subfloor must be coated with
Maxxon Floor Primer. Level-Right PLUS should not be poured without first priming the
subfloor.
Mixing
The Level-Right PLUS should be mixed using Maxxon-approved pumping equipment.
Testing
For Level-Right PLUS, field testing must be performed in accordance with modified ASTM C
109. Before independent sampling, contact the Maxxon quality control department to ensure
that proper procedures are followed.
Limitations
(1) Do not pour Level-Right PLUS where the floor temperature is less than 40º F
(4.5º C) or greater than 100º F (37.7º C)
(2) Protect the poured mortar from wind and sun, and from
freezing temperatures for the first 72 hours.
(3) The concrete subfloor must be structurally sound and able
to withstand live and dead loads with a deflection limitation of L/360.
(4) Level-Right PLUS is for interior use only; it is not a
wearing surface.
(5) Level-Right PLUS will not structurally bridge over
expansion joints, saw cuts or structural cracks. They should be allowed to continue
through the Level-Right PLUS. The architect or structural engineer must specify expansion
joints and show their location in areas that will receive hard surface floor goods such as
ceramic or marble tile, and hardwood flooring.
(6) For deeper fills, call Maxxon Corporation for the
Application Bulletin.
(7) For applications other than those over structural
concrete call Maxxon Corporation for the Application Bulletin.
(8) Concrete, moisture or vapor emission must be eliminated
by others prior to a Level-Right PLUS application for below grade, on grade or suspended
slabs.
