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.

Priming: When primer is required use the following coverages for concrete and metal; Sikalastic® FTP LoVOC primer at 200 sq. ft/gal or Sikalastic® PF Lo-VOC Primer at 200 sq. ft/gal. Apply using a brush or phenolic core roller. This will result in 8 dry mils of primer. Don’t prime over an existing crack detail coat.For primer application over asphalt contact Sika Technical Services for recommendation.  Due to age and porosity of asphalt coverage rates can change drastically.

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. The surface must be totally covered with primer with no dry spots or spots where the primer has completely absorbed into the substrate. Allow primer to become tack free before proceeding to the next phase.

Detailing:

Detail Coat: All cracks and joints between 1/16” – 1/8” must be detailed prior to installing Sikagard®-7600 HG.  Any cracks or joints under 1/16” need no special detailing prior to installation of Sikagard®-7600 HG.  To properly detail apply 6" wide and 30 mils of Sikagard®-7600 HG over all cracks and joints.

Application: Sikagard®-7600 HG can be applied at different thicknesses to accommodate different warranty requirements.  For best results Sikagard®-7600 HG should be applied in two coats.  Please follow the coverage rate section above to determine proper coverage for 30, 60, 90 mil coating layers. Allow to cure (4-6 hourshours or until surface is walkable without damaging the membrane) after initial coat and before proceeding.Sikagard® 7600 HG should be applied in the shade or during evening hours.  When applying the direct sun light it’s possible that the surface of the coating can cure too quickly and entrap solvent resulting in blisters. 

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. The maximum application thickness on vertical surfaces is 45 mils.

Recoat: At 75 °F (24 °C) and 50 % relative humidity, recoating and multiple or second coats must be completed within 16 hours from the start of the previous applications of Sikagard®-7600 HG. After this 16 hour window, it is necessary to abrade, clean and prime with Sikalastic Recoat Primer.
