PRODUCT DESCRIPTION:

  Epoxy.com Product #450HT is a liquid-applied, single component, moisture-cured, seamless, slip resistant, polyurethane, waterproof deck coating. The system consists of Epoxy.com Product #452HT BASE COAT and INTERMEDIATE COAT, and Epoxy.com Product #416HT TOP COAT, and a primer, where necessary. MANUFACTURER: Epoxy.com a division of Epoxy Systems, Inc.

BASIC USES:

For waterproofing parking decks and concrete roof decks. Epoxy.com Product #450HT can be used on all decks where a skid-resistant, long lasting, wear-resistant surface is required. It may be used on new decks as well as on existing concrete decks which are damaged or cracked. The system is suitable for exterior, as well as interior applications in all kinds of climates. The coating retains its elastomeric properties in below freezing weather, as well as in very hot climates.

LIMITATIONS:

All materials shall be delivered to the job site in unopened containers clearly marked and labeled. Containers that have been opened must be used up within one or two days since it is a moisture-reactive material. The material will cure when exposed to air. All surfaces must be completely free of foreign matter and primed, where necessary.

STANDARDS:

A.S.T.M. C-957-05. COLORS: Concrete grey and tan.

MATERIALS:

Recommended materials and their uses are as follows: Epoxy.com Product #910 is a one part, self-leveling or gungrade, non-staining, polyurethane sealant which cures at ambient temperature to a firm, flexible tear-resistant rubber. It is highly resilient and has excellent recovery characteristics after extended periods of compression or elongation. Epoxy.com Product #886: A two-component, solvent based epoxy primer for use on concrete or metal surfaces. Epoxy.com Product #452HT COATING: A one-part, self-leveling, polyurethane coating used as the elastomeric waterproof membrane of the system, and also to lock in the aggregate. Epoxy.com Product #416HT COATING: A one-part, moisture- cured, aliphatic polyurethane topcoat which protects the Epoxy.com Product #450HT from U.V exposure.

 

AGGREGATE:

20 mesh Monterey sand or equal, which imparts the slip resistant texture and contributes to wear resistance.

CONDITION OF SURFACES:

A. Before coating work is commenced, surface shall be reinspected and treated as necessary to remove laitance, loose material on the surface, grease, oil and other contaminants which will affect bond of the coating. The following paragraph requires a “mat test” which is accomplished by placing a 2’ x 2’ (0.6m x 0.6m) non-breathing rubber or vinyl mat directly onto the substrate. The edges of the mat are to be taped to the surface. The mat is removed after a minimum of 4 daylight hours. If there is no visible condensate, the Applicator may begin coating operations.

B. Concrete surfaces shall be visibly dry and pass a 4-hour rubber mat test (no condensate) prior to application of coating system. Mat shall be taped to deck on all sides.

C. Verify that only sodium silicate based curing compounds have been used to cure concrete in areas to be coated

D. Metal surfaces shall be dry, clean, free of grease, oil, dirt, rust and corrosion, other coatings and contaminants which could affect bond of coating system, and without sharp edges or offsets at joints.

E. Commencement of coating installation implies acceptance of that surface area, as it regards the suitability of the surface to accept the coating systems.

INSTALLATION SURFACE PREPARATION:

A. Thoroughly clean all surfaces to receive coating materials in strict compliance with Manufacturer’s written instructions and recommendations. Remove oil and grease with a commercial grade alkaline cleaner; thoroughly rinse and dry. Prepare all concrete surfaces by sandblasting, shotblasting, or acid etching with a 10-15% solution of muriatic acid. Flush all acid with clean water and allow to dry.

B. Rout or sawcut all cracks exceeding 1/16” (.16cm) in width and caulk with Epoxy.com Product #910 or Epoxy.com Product #906 or #907.

C. Caulk all expansion, control and construction joints to be overcoated by deck coating with Epoxy.com Product #910.

D. Protect adjacent surfaces with drop cloths or masking as required.

FLASHINGS:

A. Provide fluid applied flashings at all locations where a horizontal surface abutts a vertical surface and at all deck penetration as specified.

B. At locations of potential high movement such as wall/slab intersections which are not structurally and rigidly connected, provide 10" (25.4 cm) min. width of precured sheet flashing or reinforce coating with one layer of uncoated, woven fiberglass cloth. Where sheet flashings are used, they shall be free or unbonded to the substrate within 2" (5.08 cm) on vertical surface and 4” (10.16 cm) on horizontal surface. Do not use precured sheet flashings over expansion joints in horizontal surfaces.

C. At projections through deck coatings such as posts, vents, pipes, stanchions, railings and similar locations of potential slight movement, provide a 1/4" (0.64 cm) bead of Epoxy.com Product #910. Tool sealant to form a cove and allow to cure before overcoating.

PRIMER AND DETAIL WORK:

A. Primer: Prime all concrete, masonry and metal surfaces, except for waiver in writing from manufacturer. Apply primers at coating Manufacturer’s recommended rate. Prime coat may be allowed to completely dry but shall not be applied more than 8 hours preceding application of deck coating. Epoxy.com Product #886 shall be applied at the rate of 300 sq.ft. per gallon (7.36 m2/liter). Mix only enough for use over a 2 hour period (max.). Allow a minimum dry time of 1 hour. Install deck coating base coat on the same day.

B. Apply 25 mil (0.63 mm) dry film thickness of base coat material over all flashings (sheet flashings, sealant coves and rigid corners). Extend coating 2" (5.08 cm) beyond flashing out onto adjacent deck surface. Unless otherwise indicated on Drawings or where limited by height of base, extend coating a minimum of 1” (2.54 cm) above the top of the flashing and terminate in a neat straight line. Use masking tape for such purpose.

C. Apply 25 mil (0.63 mm) dry film thickness of base coat material over and for a distance of 1-1/2" (3.8 cm) on each side of all cracks. Do not permit coating to extend over any joints larger than 1" (2.54 cm) nominal width and/or any joints which may move in excess of 25% of nominal dimension. This requirement shall apply to detail coatings as well as deck coatings.

D. Apply 25 mil (0.63) dry film thickness of base coat material over and for a distance of 2" (5.08 cm) on each side of all expansion joints, control joints and construction joints to be coated.

APPLICATION:

A. MEDIUM AND HEAVY DUTY DECKS.

Step (1) Epoxy.com Product #452HT shall be applied to the primed concrete at a rate of 64 square feet per gallon (1.57 m2/liter) resulting in a film thickness of 25 mils (.63 cm). Application must be made uniformly to avoid thin spots and care must be taken to avoid pinholes and repair them should they occur.

Step (2) Following an overnight cure, apply Epoxy.com Product #452HT at a rate of 100 square feet per gallon (2.45 m2/liter) for a thickness of 16 mils (0.4 mm). It is preferable to use a heavy duty roller for even distribution.

Step (3) Immediately broadcast 1 gallon (3.785 liters) of 20 mesh Monterey sand, or equivalent, uniformly into the wet coating, per 100 sq.ft. (2.45 m2/liter). Assure that the coating is backrolled for even distribution of the sand. Do not broadcast to refusal. Allow to cure overnight.

*Step (4) Repeat Steps 2 and 3, where needed, as advised by the manufacturer. Allow an overnight cure of ELASTODECK 5001 HT. *For heavy-duty traffic areas.

Step (5) Apply Epoxy.com Product #416HT by roller, brush or spray at 150 sq.ft. per gallon (3.68 m2/liter) to equal 10 mils (0.25mm). Allow 72 hours for complete cure of the system. Top coat must be the same color as the preceding sand coat.

B. LIGHT DUTY PEDESTRIAN DECKS.

Step (1) As under A. Allow an overnight cure.

Step (2) Apply Epoxy.com Product #416HT at 100 square feet per gallon (2.45 m2/liter) or 16 (0.4mm) wet mils. Immediately broadcast 1 gallon of 20 mesh Monterey sand, or equivalent, uniformly into the wet coating, per 100 sq.ft (9.29 m2). Assure that the coating is backrolled for even distribution of the sand. Allow an overnight cure before permitting light traffic.

MAINTENANCE:

Since, as with all deck coatings, the topcoat is subject to staining by such foreign matter as nitrates, fertilizers, hard water, and other substances, it must be maintained. Please contact Epoxy.com Technical Support for proper maintenance procedures. The manufacturer is not liable for staining caused by hard water deposits, nitrates, fertilizers and other foreign matter. If Epoxy.com Product #450HT is damaged, it can be repaired by cleaning the surface and recoating it with Epoxy.com Product #450HT
