Building Surface Repair Coating(RMO), Factory supply.
Concrete Repair Polymer(RMO) is a proprietary admixture designed to
be used as a modifier for Portland cement. It gives Portland cement
unusual and unique properties not obtainable from other admixtures
or modifiers. Goodcrete RMO contains proprietary copolymer
components, which induce cross linking in the presence of Portland
cement, producing a chemical as well as mechanical bond both
adhesively and cohesively.
1. Superior adhesive strength.
2. Flexibility without fatigue.
3. Superior freeze-thaw capabilities.
4. Waterproofs and seals.
5. Excellent primer/bond coat for secondary coatings & systems.
6. Weather, abrasion and UV resistant.
7. Easy to apply, clean with water.
8. Non-toxic, environmentally friendly.
9. Non-reemulsifiable waterborne copolymer.
10. Creates virtually any type of surface texture.
All concrete, wood, asphalt, masonry, metal and other surfaces must
be structurally sound, clean and
free of coatings, curing compounds, dirt, oils, grease, laitance,
efflorescence, mildew, fungus, or any
contaminant that prevents good adhesion.Remove coatings &
contaminants using approved methods
such as shot blasting, sand blasting or high pressure water
Allow new concrete to cure a minimum of 72 hours prior to
Surfaces must be secured with screws to the structure, and all
holes, seams and cracks shall be
filled and then reinforced using anti-alkaline reinforcing fabric.
Minor cracks or spalls do not require pre-filling. GOODCRETE RMO
made into a flowable "Squeegee"
mix will penetrate the cracks and substrate surface creating better
adhesion than drier patching mixes.
Another method is to pour the Squeegee mix directly into the
cracks, voids, and spalled areas and
allow to self level.
Depending on the extent of cracking, an anti-alkaline ,reinforcing
fabric should be embedded into the
Squeegee mix. Refer to Squeegee Mix Application Guidelines.
Asphalt Surfaces and Cracks:
Surfaces and cracks must be completely dry prior to application.
GOODCRETE RMO makes an excep
tional repair mortar for asphalt cracks.
Note: Do not use immediately over Hot mix asphalt applications.
Chalky, dusting, and pigmented surfaces should be pre-treated with
GOODCRETE DPS and RMO
and allowed to cure for 24 hrs. Prime areas with (1) part GOODCRETE
RMO to (1-2) parts of clean
water immediately prior to application of squeegee mixes, overlays
Existing expansion joints should always be maintained. Previously
filled joints should be masked off
prior to application. Unfilled expansion joints should be treated
using two (2) brush applications of
RMO Squeegee Mix to the joint surface to provide a continuous
waterproof surface. When dry,
expansion joints can be filled with an approved joint compound.

GOODCRETE RMO cement mixtures may be opened up to normal traffic
after the first 12-24 hours
and can normally be coated 24 to 48 hours after application. For
interior applications or those not in direct sunlight, allow 72
hours prior to overcoating.
Coverage rates vary according to design mix, porosity and profile
of surface. For example: Five
gallons of GOODCRETE RMO, mixed per standard Squeegee Mix
instructions, will yield 46 gallons
of mix. Using # 60 mesh sand and applying the mixture with a
"squeegee" will yield approximately
2,000 square feet per coat. Finer grades of sand can increase the
Do not apply GOODCRETE RMO when surface and ambient temperatures
are expected to fall below
50°F within 12 hrs.
Do not apply when precipitation is expected within 24 hours
following completion of application.
Packing: 5 US Gallon/Pail, 55 US Gallon/Pail, or 20KG/Pail, 220KG /Pail.
