Mixing

Mix each pail (4.05 gal.) of Sikagard® 7600 HG Part-B by using a mechanical mixer and jiffy style paddle at slow speed for 1.5 minutes minimum to ensure a homogeneous material. Take care not to allow entrapment of air into the material. Do not mix in an up and down motion. While mixing, slowly add one 0.45 gallon pail of Sikagard® 7600 Part-A to the pail. Once Part-A has been added, mix for 3 minutes. Please do not estimate to avoid any mixing errors. Do not thin. Do not hand mix. Mix the whole pail. Do not batch.

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 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® 7600HG 6" on each side of the joint.  Bridge joint with 12” Sika Fleece 120 strip pushing it into the Sikagard® 7600HG . 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.f/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 squeege and backroll .  Please note that potlife 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.
