Mixes ought to be tested, and tweaked if preferred, each and every fabricator's discretion. For those who have a recipe you want to see featured here, please call us.

Make certain to look at our 40oz. Mixing Cups (offered here). very helpful for those stages of mixing and dosing concrete, additives, and color- additionally to mixing the concrete sealers.
Fundamental Concrete Countertop Mix. (by Expressions Limited)

• 1x 80 lb. bag of normal concrete mix (out of your local home improvement store of preference)
• 5 lbs. Portland I/II Cement (offered in 94 lb. bags usually, local home improvement store)
• 2 oz. AR Glass Fibers (in regards to a golf-ball sized portion) - Offered HERE
• two tablespoons Riteks SP7000 Superplasticizer/Water Reducer - Offered HERE
• MIX: Combine 80 lb. bag of concrete with 5 lbs. of Portland Cement and AR Glass Fibers. In clean 5-gallon bucket, add 2 quarts of fresh water, and blend by 50 percent Tablespoons Riteks SP7000 Superplasticizer. Combine mix water with concrete, and start mixing. Add small quantities of additional water** until concrete mix resembles those of thick oatmeal.
  • **Some applications may need a drier concrete mix (for example pressing very dry concrete right into a form with the aim of creating large voids- to become filled later having a different colored cement slurry), or perhaps a wetter mix (filling a vessel sink 2-part sink mold), so adjust water accordingly.
• COVERAGE, WEIGHT, and charges:
  • Coverage: This combination will product just a little above .6 cubic ft of concrete. At 1.5" thickness, it'll yield roughly 4.8 square ft. At 2" thickness, it'll yield roughly 3.6 square ft.
  • Weight: At 1.5" thickness, approximately. 21 lbs. per sq. foot. At 2" thickness, approximately. 28 lbs. per sq. foot.
  • Costs: Material costs for concrete, cement, fiber, and plasticizer is @$4.10 per bag. This equals to be $.85 per sq. foot. at 1.5" thickness, $1.14 per sq. foot. at 2" thickness.
• Notes: Most traditional 80 lb. bags of concrete mix cost around $3.00, and also have somewhere near 15 lbs. price of Portland Cement inside them- the remainder is sand and gravel. Growing the Cement content as much as around 20 lbs. is the same as the greater costly concrete mix, for example "Quikrete 5000" concrete mix. The primary idea behind mixing concrete is by using minimal quantity of water to get the concrete to become workable. The less water used, the more powerful the cured concrete is going to be. Utilization of additives, for example Plasticizer (also referred to as Water Reducer) permit the concrete to 'flow' so that you can use it, using less actual water.

Supreme Concrete Countertop Mix. (by Expressions Limited)

• 1x 80 lb. bag of normal concrete mix (out of your local home improvement store of preference)

On Your Own Countertop Mix. (by Expressions Limited)

• 25 lbs. Portland Cement (Use Type I rather of Type I/II for pre-cast)
  • This recipe is nice if you wish to use White-colored Portland Cement for the mix.
• 60 lbs of sand/stones. Make certain it's washed so there's no dirt or fine dust. It's okay for that sand to become moist when weighing it. A great beginning point is 40 lbs. sand 20 lbs. stones.
  
  • Think about using quarta movement sand (it's white-colored) if using White-colored Portland Cement, to assist the concrete piece be as white-colored as you possibly can.
• 2 oz. AR Glass Fibers (in regards to a golf-ball sized portion) - Offered HERE
• two tablespoons Riteks SP7000 Superplasticizer/Water Reducer - Offered HERE
  • Optional (For any more powerful, better concrete): Add 5 lbs. VCAS (Replaces the five lbs. of Portland Cement, therefore if adding VCAS you need to lessen the Portland Cement in the first step to twenty lbs.). - VCAS Offered HERE .
  • Optional: (For any more powerful, better concrete) Add 2 lbs. Polyplex with mix water just before mixing with concrete. - Offered HERE
    
• MIX: Combine sand/gravel in mixer and let mix a couple of minutes. Include Portland Cement (and VCAS if utilizing it), and blend (cover mixer if at all possible to avoid dust messes). Add some AR Glass Fibers and blend just lengthy enough to spread them out. In clean 5-gallon bucket, add 2 quarts of fresh water, include two tablespoons of Riteks SP7000 Superplasticizer (and add some 2 lbs. of Polyplex if utilizing it). Combine mix water with concrete, and start mixing. Add small quantities of additional water** until concrete mix resembles those of thick oatmeal.

  • Weight: At 1.5" thickness, approximately. 21 lbs. per sq. foot. At 2" thickness, approximately. 28 lbs. per sq. foot.
  • Costs: Average material costs for cement, sand, gravel, fiber, and plasticizer is @$4.25 per batch. This equals to be $.89 per sq. foot. at 1.5" thickness, $1.18 per sq. foot. at 2" thickness.
• Notes: Most Portland Cement bags are 94 lbs. then sell for approximately $9.00. Sand and Gravel can be bought in a home improvement store, already bagged, for any premium cost. The greater economical method of getting sand/gravel is to buy it from the gravel pit, or frequently occasions a concrete plant (the people using the concrete trucks driving around) enables you to come buy some inexpensive, or create it for you free of charge for a small amount.
  

GFRC (Glass Fiber Reinforced Concrete) Mix. (by Expressions Limited)

GFRC (Glass Fiber Reinforced Concrete) is lighter, more powerful, faster, and less expensive than most frequent concrete mixes.

GFRC pieces could be de-molded after 24 hrs.

An Average GFRC mix 1:1 ratio means One 90 lb. sack of cement and something 100 lb. bag of sand.

For a lot of countertop type applications, smaller sized batches are sufficient, for example 1/4 this amount.

The Expressions-Limited Fundamental GFRC Mix below is effective for GFRC countertops, sinks, and furnishings.

The Equipment: 5 Gallon Bucket. Durable Electric Mixer and Paddle Mixing Blade. Scale. Calculating Cup(s). Hopper Sprayer and Air Compressor. Compaction Roller(s).

• FACE COAT:
  • Add 6.5 lbs. water (about 3 quarts) to some clean 5 gallon bucket.
  • Add 2.5 lbs. of Polyplex Curing Aid.
  • Add 1 Fl. Ounce of SP 7000 Super Plasticizer.
  • Add 23.5 lbs. of #30 Silica Sand (#30 may be the sand size, and offered at the local home improvement store).
  • Add 17.5 lbs. Portland Cement (white-colored or grey, offered at the local home improvement store)
  • Add 6 lbs. Vitro Minerals Pozzolans (VCAS).
  • Optional: Add any Integral Color. if preferred.
  • Add extra water as needed, in a small amount, until mix is creamy.
  • Let mix 'set' (usually about a few minutes) after which remix briefly.
  • Spray Face Coat of the mix within the mold/form work utilizing a Hopper Sprayer. Face coat ought to be 1/8" - 3/16" thick.
  • Coverage: It takes approximately 2 lbs. from the cement mix to pay for 1 sq. foot. (meaning should you chose to make this batch within this exact size, you can anticipate around 25-30 sq. foot. of coverage for that face coat)
  • Allow face coat to sit down lengthy enough to stiffen, but remain moist (Time varies, usually 30-an hour).

• BACKER LAYERS:
  • Mix another batch, same formula as above.
  • Gradually add 1.6 lbs. of threeOr4" Length AR Glass Fibers.
  • Hands lay the fiber-wealthy backer layer mix over the top of mold/form in a 3/8" - 1/2" thickness.
  • Use Compaction Rollers to balance out this layer, condense, and take away any air pockets.
  • Convey a second backer layer, again 3/8" - 1/2" thickness, little with rollers.
  • Finished piece ought to be 3/4" - 1" thick at least.
  • Coverage: It takes approximately 6 lbs. from the cement mix to pay for 1 sq. foot. around 3/8" thickness (meaning should you chose to make this batch within this exact size, you can anticipate around 8-10 sq. foot. of coverage per backer layer)
  • Additional layers could be added, or perhaps a slightly wetter mix may be used last to 'top off' the mold form, and even out the concrete.

• EXTRA REINFORCING:
  • Extra Reinforcing: Fiberglass Scrim Fabric can be put between GFRC Backer layers.
  • Fiberglass Scrim can help increase overall strength and versatility. Well suited for reinforcing around integral concrete sinks.
  • Keep Scrim 1/2" from the Face Coat, to prevent ghosting (faint lines showing a picture of something hidden within the concrete).
  • Another layer of Scrim could be set within the final coat of GFRC, and gently folded lower in to the cement surface.

• COVERAGE, WEIGHT, and charges:
  • Face Coat Batch: Covers approximately. 80 sq. foot. at 1/8" thickness.
  • Backer Layer Batch: Covers approximately. 30 sq. foot. at 3/8" thickness.
  • Finished GFRC Piece Weight: At 3/4" thickness: 8 lbs per sq. foot. At 1" thickness: 10.5 lbs per sq. foot.
  • Material Cost Approximates: At 3/4" thickness: @$1.99 per sq. foot. At 1" thickness: @$2.65 per sq. foot.
