Mixing

It is essential that proper mixing methods and tools are used to ensure proper application of Sikagard®-7600 HG.

• Mixing Drill: Low Speed Mixing Drill ( 400-600 rpm)
• Mixing Paddle: Jiffy Mixer ( 5-50 Gallon Model) or Mud Mixing Paddle ( 9-5/8" WIDE x 6-1/4" DEEP)
• Premixing: Premix each pail of Sikagard®-7600 HG Part-B (4.05 gal.) using the recommended drill and mixing paddle at slow speed for a minimum of 1.5 minutes to ensure Sikagard®-7600 HG Part B is a homogeneous mixture.
• Mixing A & B component: With mixing paddle in the Part-B, turn on mixing drill and begin mixing Sikagard®-7600 HG Part B, and while the mixing paddle is spinning slowly add one 0.45 gallon can of Sikagard®-7600 HG Part-A to the center of the vortex created by the mixing paddle. Once Part-A has been added, mix continuously for an additional 3 minutes using a very slow up and down motion, making sure full pail is mixed evenly, including the sides of the pail.
• NOTE:  Take care not to allow entrapment of air into the material. Do not mix in an aggressive up and down motion. Do not estimate mixing time. Do not thin. Do not hand mix. Mix the whole pail. Do not batch down.  If a greenish hue can be seen at the top of the pail then product has not been mixed properly.

Phase 1 (Primer): When required; prime the surface at the rate of 1 gal / 200 - 300 sq.ft. . Apply using a brush or phenolic core roller. This will result in 5 - 7 dry mils of coating. Priming is optional. Don’t prime over an existing detail coat.

NOTE: For rough or porous concrete or when outgassing is a concern, use Sikalastic® PF Lo-VOC Primer or Sikalastic FTP LoVOC Primer at an approximate rate of 180 - 230 sq.ft/1 gal. This rate may vary on the porosity of the substrate. Allow primer to become tack free before proceeding to the next phase.

Phase 2 ( Cracks, Joints, Detailing):

Detail Coat: Apply 30 mils of detail coat Sikagard® 7600 over all joints, transitions, cracks and flashing. Cracks in concrete/asphalt over 1/8” must be filled with Sikagard® 7600. Using Sikagard® 7600 as caulking compound will shorten the curing time over conventional polyurethane caulks.

Reinforced Detail Coat: Apply 15 mils of detail coat Sikagard® 7600  over all joints, cracks and flashing. Cracks in concrete/asphalt over 1/8” must be filled with Sikagard® 7600. Bridge joints, cracks, and flashings with 3” or 6” FlexiTape Heavy pushing it into the Sikagard® 7600 HG  over all joints, cracks and flashings. Over reinforcement , apply 10–15 mils stripe coat of Sikagard® 7600 and taper it onto adjacent surface. Allow the surface to cure for 4-6 hours before the next phase.

Reinforced Joint Detail : Apply 60 mils strip coat of Sikagard® 7600 HG 6" on each side of the joint.  Bridge joint with 12” Sika Fleece 120 strip pushing it into the Sikagard® 7600 HG . Over reinforcement, apply 60 mils stripe coat of Sikagard® 7600 and taper it onto adjacent surface. Allow the surface to cure for 4-6 hours before the next phase.

Phase 3 (Coat #1): The first coat of Sikagard® 7600 HG  should be applied at the rate of 48 sq.ft/1 gal. resulting in 30  dry mils of membrane . Allow to cure (4-6 hours) before proceeding to Phase 4.

Phase 4 (Coat #2): Apply the second coat of Sikagard® 7600 HG  at the rate of 48 sq.ft./1gal.  resulting in 30  dry mils  of membrane.

NOTE: If priming is not required skip Phase 1, and proceed with Phase 2 . Any adhesion test is to be performed 3 days after product application.

Sikagard 7600 HG can be applied over horizontal  and vertical surface. Apply using a 3/8” roller or notched squeegee and back-roll .  Please note that pot life for Sikagard 7600 HG is only 30 minutes.

Recoat: At 75 °F (24 °C) and 50 % relative humidity, recoating and multiple or second coats must be completed within 16 hours of previous

applications of Sikagard® 7600 HG. After this 16 hour window, it is necessary to abrade, clean and prime surface  prior to recoating.

Reinforcement: please contact Sika Technical Service (polyester scrim is optional).

Removal: Equipment should be immediately cleaned with an environmentally safe solvent, as permitted under local regulations.
