GARDOX®

HORIZONTAL JOINT SEALANT
Seals concrete horizontal joints against water infiltration with a durable and flexible rubber-like seal.

SEALTIGHT GARDOX Horizontal Joint Sealant is a pourable, two-component, cold-applied compound that forms a tough, durable, rubber-like seal in horizontal concrete joints.

Description
SEALTIGHT GARDOX Horizontal Joint Sealant is a pourable, two-component, cold-applied compound for sealing joints in concrete. Chemically reactive polymers, plasticized with coal tar, cure to a durable, rubber-like joint seal that offers a firm, smooth, non-tracking surface retaining flexibility from -20ºF (-29ºC) to over +200ºF (93ºC). Effectively seals the joint against water infiltration and rejects incompressibles.

GARDOX is resistant to jet fuels, most common solvents and chemicals. GARDOX will accommodate a joint movement of ±25% when correct joint design techniques are followed in regard to the accommodations of anticipated joint movement and the proper joint width of twice the depth [1/2'' (12.7mm) minimum] ratios.

Uses
SEALTIGHT GARDOX Horizontal Joint Sealant is recommended for sealing horizontal joints on highways, airport runways, bridges, plaza decks and driveways. Interior uses include sealing joints in industrial floors, garage floors, airplane hanger floor joints, etc.

Application Tools

 

 
Electric drill with flat-bladed paddle

 
Wooden hand paddle

Application
JOINT SIZES: GARDOX Horizontal Joint Sealant should be used in joints not less than 1/4" (6.35mm) wide. A 2:1 width-to-depth ratio should be maintained. However, in no case should joint sealant depth be less than 1/4' or exceed 1/2". Proper joint design practices and application techniques must be followed for successful performance.

JOINT PREPARATION: Remove foreign substances, incompressibles and free water from joint opening. For proper adhesion, joints must be clean and dry. Dust, dirt and laitance should be removed prior to application. GARDOX adheres well to unprimed concrete; however, the use of P/G Primer is recommended for optimum adhesion.

To control sealant depth, insert SEALTIGHT KOOL-ROD Backer Rod in the joint before sealing. For larger joints, where additional support is required, use a non-asphaltic joint filler such as CERAMAR Flexible Foam Expansion Joint Filler. For straight joint edges, mask off top surfaces with masking tape.

METHOD OF APPLICATION: Pour polymer component into larger base material container. Blend in a 1:1 ratio. Mix entire unit. Blend thoroughly, either by hand mixing with a wooden paddle or with a slow-speed drill and flatbladed paddle.

NOTE: GARDOX has a work life of approximately 3 hours; less at temperatures above 70ºF (21ºC). Next, pour GARDOX into joint with suitable pouring container Clean tools with Xylene or Toluene and remove masking tape before the sealant cures. GARDOX will self-level and cure to a rubber-like compound in 72 hours at air and surface temperatures above 70ºF (21ºC). Sealant will be tack-free in 12 hours.

Coverage
7.47 gal./ft³ (1,000 L/m³). A 1/2" x 1/2" (12.7 x 12.7mm) joint will require 1.3 gallons/100 lineal feet (16 L/100m).

Limitations / Precautions
GARDOX components are pre-measured to exact quantities. Mix all materials in container; do not mix partial units or dilute. Do not use GARDOX at temperatures below 40ºF (4ºC) or in wet joints. If expected movement is greater than +/- 25%, GARDOX should not be used in this application. Do not apply GARDOX to galvanized surfaces. GARDOX may be used on steel and other non-galvanized metals only when the surfaces are first cleaned to bright metal, acid etched and P/G Primer is used.

GARDOX is not recommended for swimming pools, joints subjected to hydrostatic pressure, joints in ice rinks or parking decks. GARDOX is not compatible with asphaltic joint fillers or asphaltic concrete pavements.

Health Hazards
Avoid contact with skin or prolonged breathing of vapors. Refer to Material Safety Data Sheet for complete Health and Safety Information.

Packaging
1 gallon Unit consists of a 1/2 gallon (1.89 liters) of base and 1/2 gallon (1.89 liters) of catalyst in an imperial gallon container.
4 gallon Unit consists of 2 gallons (7.57 liters) of catalyst in a two-compartment 5 gallon (18.93 liter) pail.

Shelf Life
GARDOX should be stored in a cool warehouse. Like many top-quality, two-component sealants, GARDOX has a limited (maximum 6 months) shelf life and should be used as quickly as possible after purchase.

NOTE: Do not open pail until ready to use as this significantly reduces shelf life.
