Heavy Duty Epoxy Patch

DESCRIPTION: Premium quality, 100% solids epoxy resin binder specifically designed for aggregate filled flooring systems. Contains no solvents (zero VOC) or carcinogens and has minimal odor to assure low toxicity and ease of application. Excellent wetting ability and provides an exceptional bond to concrete surfaces. As an aggregate filled binder, develops high compressive and flexural strength for optimum performance.

SUGGESTED USES:

Moisture tolerant concrete primer

Binder for aggregate filled mortars

Self-leveling slurry binder

Crack repairs

May be used to bond wood, steel, and other dis-similar products to concrete substrate

Follow general surface preparation and application procedures specified in ACI 503.1-4.

Do not apply to concrete less than 30 days old.

Do not apply to concrete with curing or sealing membranes.

Do not apply to base concrete at a temperature less than 50⁰ F.

Concrete surfaces must be structurally sound and free from contaminants such as dust, oil or dirt. Surfaces must be shot blasted or mechanically abraded to achieve a minimum 5 mil profile. Coated surfaces must be mechanically cleaned and abraded with 60-80 mesh sandpaper and approved by the manufacturer before coating. A calcium chloride test is recommended and hydrostatic pressure must be <5psi before epoxy coatings application. Free-standing water must be removed.

Thorough and complete mixing is critical, a Jiffy mixer is recommended. First mix each component separately. Proportion each component at the ratio of 2 parts A (resin) to 1 part B (hardener) by volume or, if using 1-gallon kits, pour all of Part B (hardener) into Part A (resin) and mix at 400-600 RPM for 3-5 minutes. In case of pigmented material, no stripes or color variation should be visible. Use an up and down motion, scraping the mixing container sides and bottom. Mix no more material than may be applied in 20 minutes.

Prime surfaces with patching compound by roller, brush or squeegee. Normally applied at a rate of 175 - 200 sq.ft. per gallon. Application of mortar can proceed while primer is still wet. Allow primer to become tacky before applying a slurry or mortar.

Mix parts "A" and "B" thoroughly first, then add 3-7 parts suitable aggregate (such as B-23 washed river rock) and mix until the aggregate is completely wetted and uniform. Apply by trowel to desired thickness. Chemical resistance and appearance is enhanced by applying a neat coat of patch over the cured mortar prior to top coat application. Note that product working life is extended when mixed with aggregate, dependent on batch size and temperature.

Mix parts "A" and "B" thoroughly first, then add 1 part by volume suitable slurry filler (such as "marble-white") and mix until uniform. Apply the slurry by squeegee.

Ultimate Patch is suitable for repairing of cracks in concrete slabs. It may be poured or injected.
