PART 3 EXECUTION
3.1
EXAMINATION
1.
Examine surfaces to receive moisture vapor reduction barrier, underlayments, and toppings and
conditions under which they will be installed.
2.
Assure that surfaces to be installed upon do not contain any kind of sealer or organic compounds.
8/13/13
5
3.
Before installation, use tests (ASTM F 1869, ASTM F 2170, and/or ASTM F 2420) carried out by
Architect/Engineer during study phase, and confirm by testing through installer or independent
laboratory prior to installation.
4.
Test the surface for direct tensile bond strength per ASTM C 1583 prior to installation. The pull-out
value must be ≥ 200 psi (1.2Mpa) with the failure at a depth of ≥ ¼“ (6mm) into the base with ≥
50% failure of the substrate
5.
Do not proceed with work until surfaces and conditions comply with requirements required by
manufacturer's printed instructions.
3.2
PREPARATION
1.
Inspect the concrete substrate with regard to the suitability of receiving a moisture vapor reduction
coating with manufacturer’s representative.
2.
Protect adjacent surfaces not designated to receive moisture vapor reduction coating.
3.
Concrete Substrates:
1.
2.
3.
4.
5.
6.
7.
4.
Expansion Joints:
1.
2.
3.
5.
Substrates shall be stable, solid, structurally sound and >3,000 psi compressive strength after 28 days
when tested in accordance with Test Method ASTM C 109.
Concrete patching materials shall be moisture-, mildew-, and alkali-resistant, and shall be >3,000 psi
compressive strength after 28 days, when tested in accordance with Test Method ASTM C 109
Remove existing floor coverings, coatings, adhesives, curing and/or sealing compounds,
efflorescence, dust, grease, asphalt, dirt, and any other contaminates that will inhibit the bond or deter
the proper pentration of the Moisture Guard Max onto the concrete substrate.
Concrete substrate must be pourous to acheive full pentration of the Moisture Guard Max. Roughen
the surface of all smooth formed concrete such as hard troweled surfaces, and precast panels to an
open coarse texture to increase pentration.
The concrete surface shall be mechanically profiled by shot blasting, sand blasting or scarifying to
achieve a CSP 3 to CSP 5 standard. Grinding is allowed only in areas not accessible by shot blasting,
sand blasting or scarifying. Surface preparation by acid etching is not permitted.
Concrete substrate must be free from liquid and/or standing water to ensure full pentration of the
Moisture Guard Max.
The surface must be a minumum of 5 degrees F above the dew point temperature and not have
hydrostatic pressure at the time of application.
Honor all expansion and control joints.
Remove all loose material from the joint. Coat the inside of the joint with Moisture Guard Max to the
desired thickness.
Allow Moisture Guard Max to cure a minimum of 12 hours prior to the installation of the backer rod and
sealant.
Non-Moving Cracks and Voids:
1.
2.
3.
4.
Thoroughly clean and repair all non-moving cracks and voids prior to installation of Moisture Guard
Max.
Remove all loose debris from the non-moving cracks and voids.
For openings less 1/8“ (3mm) width, Moisture Guard Max can be used neat.
For openings greater 1/8“ (3mm) width, use 48 ozs of mixed Moisture Guard Max mixed with 5 lbs. Of
ProSpec Feather Edge or ProSpec Floor Patch Pro.

Mixing:
1.
8/13/13
INSTALLATION
Do not mix more material than can be applied in 15-20 minutes. Higher temperatures will reduce the
working time.

7.
8.
9.
2.
Allow Moisture Guard Max to acclimate to room temperature at 65 degree F – 75 degrees F (18°-24°C)
for a minimum of 24 hours.
Mixing ratio is 2 parts A to 1 part B, by volume.
Remove part A and Part B containers from the outer mixing pail. Add part B (yellow) to the mixing pail,
scraping the sides to remove all material
Pour part A (blue) into Part B making sure all of Part A is transferred into Part B.
Mix for two (2) minutes with a jiffy (paint) style mixing paddle attached to an industrial drill at low speed
(< 400 rpm).
Scrape the sides and corners of the mixing pail to incorporate any unmixed material. Continue mixing
until a smooth, homogeneous, translucent green consistancy, typically 1 (one) minute.
Avoid over-mixing as this will incorporate air into the mixture.
Immediately pour the mixed material in a ribbon onto the surface, empty pail completely.
Application:

5.
6.
Temperature shall be a minimum of 50 degrees F (10 degrees C) and shall not exceed 90 degrees F
(32 degrees C).
Apply a smooth even coating over the concrete substrate using a flat squeegee followed by a 3/8“ nap
roller to achieve the desired thickness.
Due to its low viscosity the Moisture Guard Max will flow into low areas filling all voids in the concrete
substrate.
Allow the coating to cure for a minimum of 12 hours before appling any material on top of the Moisture
Guard Max.
After curing, imperfection such as low coating thickness and/or pinholes must be corrected with a
second application of Moisture Guard Max, prior to installation of any material. Allow the first coat to
cure a minimum of 12 hours prior to application of a second coat.
Apply the next layer of the finished flooring system within a maximum of 5 days of the final coat and
only with an approved primer for use over the Moisture Guard Max.
3.4
1.
2.
Clean tools immediately and before the Moisture Guard Max cures using Xylene or MEK following all
handling and safety precautions listed on the solvent container. Be sure to use rubber gloves when
cleaning and have plenty of ventilation
Cured Moisture Guard Max can be removed only be mechanical abrasion
