INTRALOK®

BONDING AGENT
SEALTIGHT INTRALOK Bonding Agent is a tough, durable, ready-to-use interface or intramix bonding agent. It assures a tenacious bond on interior concrete repairs between new-to-old or new-to-new concrete.

TECHNICAL DESCRIPTION
SEALTIGHT INTRALOK Bonding Agent is a high-solids content, water dispersion of bonding polymers compounded specifically for modifying Portland Cement compositions. It is a milky-white, non-yellowing liquid ready for use as an interface or intramix bonding agent. When properly mixed and applied, INTRALOK forms a bond between new-to-old or new-to-new concrete.

Cement mortars modified with INTRALOK are hard, tough and durable. It offers superior flexural, adhesive and impact strengths plus excellent abrasion resistance. INTRALOK reduces permeability and chloride intrusion, improving freeze/thaw resistance and reducing rebar corrosion.

INTRALOK-modified concrete is unaffected by most industrial chemicals and will not yellow or discolor.

USES
INTRALOK's most common uses are for interior patching and resurfacing, spray and fill coats, precast repairs and industrial flooring applications.

INTRALOK is ideal for interior bonding, topping, leveling, patching and dressing of concrete and masonry. As a bonding grout, it improves the adhesion of pneumatically applied concrete or mortar. INTRALOK-modified mortars provide excellent adhesion to a variety of surfaces, including concrete, masonry and brick. The result is a more attractive, durable, uniform concrete finish which costs far less than polishing or rubbing.

INTRALOK is also ideal for use as an interface or intramix bonding agent in bonding grouts, topping mixtures, finishing and mortar mixes.

FEATURES AND BENEFITS

For normal mixing, dry blend the Portland Cement and sand. Mix the INTRALOK and water together, add the cement-sand mix and then mechanically blend the complete mix thoroughly. The quantity of water should be determined by trial mix...where only 50% of the water is first added to the INTRALOK before adding to the sand-cement mix. After thorough preliminary mixing, add increments of additional water until the desired consistency is obtained.

Application Mixes by Volume

1. Bonding Slurry:

1 part INTRALOK
5 parts Portland Cement
2.5 parts fine sand (ASTM C 144)
Water: Enough for a thick, creamy consistency (Approximately 1 part).

One-gallon unit of INTRALOK used to mix a bonding slurry will yield approximately 0.47 cubic feet (.014m²), enough to cover an area of 90.24 feet (8.45m²) at 1/16" (1.59mm) thickness or 45 square feet at 1/8" (3.18mm) thickness. Apply with a stiff bristle brush, be sure to work bonding slurry into existing concrete pores.

2. Topping and Shallow Patching Mix:

1 part INTRALOK
5 parts Portland Cement
15 parts fine sand (ASTM C 404, Size #2)
Water: Enough for trowelable consistency (Approximately 2 parts).

3. Mortar Mix:

1 part INTRALOK
5 parts Portland Cement
15 parts fine sand (ASTM C 404, Size #2)
Water: Enough for desired consistency (Approximately 1-1/2 to 2 parts).

One gallon of INTRALOK used in a topping or mortar mix will yield approximately 1.8 cubic feet (.05m³) to cover an area of 86 square feet (7.99m²) at 1/4" (6.35mm) thickness. Topping or mortar mix should be applied while the INTRALOK Bonding Grout is still soft and plastic.

4. Finish Mix: (For non-traffic surfaces)

1 part INTRALOK
10 parts Portland Cement
10 parts fine sand (ASTM C 404, Size #2)
Water: Enough for stiff, brushable consistency (Approximately 4 parts).

INTRALOK Bonding Grout must be thoroughly worked and scrubbed onto the prepared concrete surface in order to realize maximum bonding efficiency.

Packaging
1 gallon (3.79 L) Units (4 per carton)
5 gallon (18.93 L) Pails
55 gallon (208.20 L) Drums

COVERAGE
Approximately 300 square feet per gallon (7.36m²/L) straight; diluted with equal parts of water, approximately 600 ft.² per gallon (14.73m²/L).

PRECAUTIONS
Keep from freezing. Approximate work life is 30-40 minutes at 70°F. Use care in finishing thin overlays. Wood float when possible. Steel troweling should be limited to a minimum number of passes 10-15 minutes after placement. When INTRALOK is used in a bonding grout and the patch topping is plain concrete, use a membrane curing compound. If the patch or topping contains INTRALOK as an admixture, wet curing is not recommended.

INTRALOK Bonding Grout or Topping Mix should be mixed thoroughly to remove lumps. Avoid air entrapment. Clean tools with water immediately. Follow all cautions on container labels. Do not add to premixed grouts. Specifier and user shall determine suitability of product for specific applications and assume all responsibilities in connection therewith. INTRALOK has an effective shelf life of 6 months from the date of manufacture.

Note: Increased amounts of various fillers, extenders or additives in the concrete mix can result in the concrete having a higher than normal porosity and some very porous hot spots. Coverage ratios must be adjusted to compensate for resulting penetration and additional coverage coats required to provide proper surface treatment. Read and follow application information and precautions. Refer to Material Safety Data Sheet for complete Health and Safety Information.
