Mixing

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

• Mixing Drill: Mechanical Mixer ( 400-600 rpm)
• Mixing Paddles: Jiffy Style Paddle ( 5-50 Gallon Model) or Mud Mixing Paddle ( 9-5/8" WIDE x 6-1/4" DEEP)
• Premixing: Premix each pail of Sikagard®-7600 VG Part-B (4.05 gal.) by using a mechanical mixer with a jiffy style paddle or a mud mixing paddle at slow speed for a minimum of 1.5 minutes to ensure Sikagard®-7600 VG Part B is a homogeneous mixture in pail.
• Mixing A & B component: After premixing continue to mix Sikagard®-7600 VG Part B, slowly add one 0.45 gallon pail of Sikagard®-7600 VG Part-A to the vortex created while mixing Sikagard®-7600 VG Part B. Once Part-A has been added, mix continuously for 3 minutes.
• Take care not to allow entrapment of air into the material. Ensure mixed evenly including sides of pail.  Do not mix in an aggressive up and down motion. Do not estimate mixing time to avoid any errors. Do not thin. Do not hand mix. Mix the whole pail. Do not batch down.

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.f/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 over all joints, cracks and flashings. Over reinforcement tape, 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.   

Phase 3 (Coat #1): The first coat of Sikagard® 7600 VG  should be applied at the rate of 48 - 24  sq.f/1 gal.  resulting in 30 - 60 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 VG  at the rate of 48 - 24 sq.ft./1gal.  resulting in 30 - 60 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 VG can be applied over vertical and overhead surface. Apply using a trowel. Please not that potlife for SG 7600 VG is only 20 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 VG . 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.
