The GFRC Blend Concrete Mix was engineered to be the perfect universal concrete bagged mix for any concrete application. Many concrete mixes are engineered too specifically towards unique applications, leaving a void for a user friendly experience. This is a perfect mix for both precast or cast in place applications. Whether you are casting a concrete countertops, sinks, fireplace surrounds, or even wall panels, this concrete bagged makes the process consistent and easy to get great results.
Applications for GFRC Blend Bag Mix:
- Easy to train with and very forgiving for new learners
- Perfect GFRC face coat spray viscosity and very temperable
- Great for flowable SCC PVA or GFRC pours
- Grabs and bonds to face coats effortlessly
- Excellent vertical wall hold and grip
- Consistent in texture, slump, and worktime
- Great hold and limited slump on high vertical walls
- Each concrete bag contains 24.3 lbs of cementitious material
- Coverage = 5 sqft at 1" thick
- This concrete bag mix is set to perform at a 30% water loading
GFRC Blend Face Coat Mixing Process:
Each climate type will yield distinct results in mix time and fluidization. Provided below is a guideline for GFRC Blend to perform well in mix temperatures at or below 70°F. Note that you may have to fine tune this process if you are using this mix at more extreme temperatures. HB7 has approximately 24.3 lbs of cementitious material per bag. For the best results, follow a rigid and consistent mix process every time.
Prep:
- Weigh out pigments in a small dish. Be sure to sift all facecoat pigments through a fine mesh screen for clean and consistent color.
- Weigh out 5 to 8 grams of Dryflow into a small dish. Amount may vary depending on geography and time of year.
- Weigh 50 lbs of dry mix (GFRC) in a clean 5 gal bucket
- Weigh out Batch Water: With or Without ice
- With Ice: In a separate & clean 5 gal bucket, add 4.3 lbs water + 1.5 lbs ice + 3 lbs of Liquid Acrylic Polymer
- Without Ice: In a separate & clean 5 gal bucket, add 5.8 lbs water + 3 lbs of Liquid Acrylic Polymer
Stage 1:
- Add 75% of the dry mix + all pigments into the water / ice (if applicable) / acrylic bucket
- Mix at high speed with a handheld mixer
- Add in the remainder of dry mix and mix at high speed until all of the dry mix has been completely blended
- Add 5 to 8 grams of Dryflow to achieve the proper mix fluidization
- Allow the mix to sit for 5 minutes
Stage 2:
- After the mix has rested for 5 minutes, mix at high speed to ensure the consistency resembles a medium viscosity milkshake
- If required, trim the mix using Liquiflow Plasticizer. We suggest keeping Liquiflow in a ketchup squirt-bottle, and only adding a little at a time to trim to the desired mix fluidization. Do not trim with water.
GFRC Blend SCC & Backer Mixing Process:
Prep:
- Weigh out pigments in a small dish. Be sure to sift all pigments through a fine mesh screen 1 for clean and consistent color. If the mix is being used as a backer coat, there is no need to sift pigments.
- For SCC mixes - Weigh out 15 grams of Dryflow into a small dish
- Weigh out 1.5 lbs of 19 mm AR Fiber - If using PVA or Acrylic fiber, choose correct loading and weight
- Pour 1 bag of dry mix (GFRC) into a clean 5 gal bucket
- Weigh out Batch Water: With or Without Ice 2
- With Ice: In a separate & clean 5 gal bucket, add 4.3 lbs water + 1.5 lbs ice + 3 lbs of Liquid Acrylic Polymer
Mixing:
- Add 75% of the dry mix + all pigments into the water / ice (if applicable) / acrylic bucket
- Mix at high speed with a handheld mixer until color and mix has fully dispersed
- Add in the remainder of dry mix and mix at high speed until all of the dry mix has been completely blended
- For SCC - Add 15 grams of Dryflow plasticizer to achieve proper mix fluidization
- For Vertical Backer Coat - Do Not add any plasticizer.
- Slowly run the hand held mixer while lifting up and down in the bucket and begin adding the 1.5 lbs of AR Fiber into the mix. Do not run the mixer at high speeds, as it will break the fiber bundles.
