For cast-in-place and or precast concrete countertops.


For optimal results, mix and formwork temperatures should be maintained between 5 °C and 30 °C (40 °F and 86 °F) for at least 24 hours prior to and 24 hours after placement.

3.0 L of water + 1 pail of SAKRETE Countertop Magic + 1 bag of SAKRETE Concrete Mix

Single pail of SAKRETE Countertop Magic and single bag of SAKRETE Concrete Mix.

First, add approximately 3.0 L (3.25 qts) of clean water into a 20 L (5 US gallon) pail and add the contents of the 5 KG (11 lb) pail of SAKRETE Countertop Magic, while mixing with a drill mixer. Then, gradually add the 30 KG (66 lb) bag of SAKRETE Concrete Mix into the pail during the mixing procedure. Once all of the components have been added to the pail, continue mixing for a minimum of 2 minutes and stop only after the material has obtained a consistent, homogeneous mix.

Multiple pails of SAKRETE Countertop Magic and multiple bags of SAKRETE Concrete Mix.

First, add the water into a concrete drum mixer. Add approximately 3.0 L (3.25 qts) of clean water for each 5 KG (11 lb) pail of SAKRETE Countertop Magic and 30 KG (66 lb) bag of SAKRETE Concrete Mix. Add the contents of the 5 KG (11 lb) pails of SAKRETE Countertop Magic and 30 KG (66 lb) bags of SAKRETE Concrete Mix into the drum of the concrete mixer, while the mixer is running. Continue mixing for a minimum of 3 minutes and stop only after the material has obtained a consistent, homogeneous mix. NOTE: For optimal results, do not exceed ½ of the recommended volume of the concrete drum mixer. Mix only enough concrete that can be placed within 30 minutes after mixing. Avoid a soupy mix. Excess water reduces strength and durability and can cause cracking.

Surface Preparation: Support the formwork in order to carry the load of the freshly placed and hardened concrete. Prepare and secure all knockouts, falsework and reinforcing steel/wire mesh (if necessary), in order to ensure movement is restricted during pouring. Ensure all surfaces to be in contact with fresh concrete are free of debris, dust and other foreign substances that may alter the surface of the finished product. Some form and knockout materials (i.e. wood) may require a light coating of form release agent to facilitate proper demoulding.

Placing: After mixing the concrete, place and consolidate inside the countertop mold. Rod the fresh concrete and tap the formwork with a hammer to help eliminate entrapped air voids. Light mechanical vibration will provide the best results and may be required for forms containing large amounts of reinforcement or closely spaced knockouts. Avoid excess vibration, as it can cause bleeding or segregation. Level concrete by moving a straight-edged board in a sawing motion, across the concrete, to remove any excess and to fill low areas. Allow freshly placed concrete to set before finishing. Set time will vary with temperature.

Precast Concrete Countertops: After concrete reaches initial set (can resist light finger pressure), finish the exposed surface as desired. Use a steel trowel, wood, magnesium or an aluminium float trowel for a smooth surface or the desired texture.

Cast-in-Place Concrete Countertops: After concrete reaches initial set (can resist light finger pressure), finish the exposed surface as desired. Use a steel trowel, wood, magnesium or an aluminum float trowel for a smooth surface or the desired texture. If the desired finish on the sides of the countertop are to match the finish of the top surface, the sides of the formwork should be removed and the sides of the countertop should also be finished at this time. Alternatively, if the finish on the sides of the countertop are not to match that of the formwork used, the form edges do not need to be removed at this time. NOTE: Finishing cementitious materials too early, or over-working the materials, can cause dusting, cracking, scaling and a weak surface.


Curing means maintaining proper moisture and temperature. Concrete should be covered with a plastic sheet that is suspended over the concrete surface, for 24 hours. Placed concrete can be removed from formwork after 24 hours.


If desired, the finished concrete countertop surface can be ground and polished, after the concrete has cured for a minimum of 3 days. Grinding and polishing should be performed using a variable speed grinder and diamond pads. Grinding will expose the aggregate present under the finished surface. Use a coarser diamond pad to expose more aggregate or a finer diamond pad to expose less aggregate. Alternatively, the surface can be polished without grinding, using a very fine grit, diamond pad. Move progressively from coarser to finer diamond pads until the desired finish has been reached. All concrete countertops intended for kitchen or bathroom use should be sealed using a penetrating or topical sealer designed for use in conjunction with concrete (refer to the sealer manufacturer for application directions and limitations). Sealing of concrete countertops intended for kitchen or bathroom use is required for sanitary purposes and to protect the finished surface from staining and wear.

Appropriate Engineering Controls
If user operations generate dust, fume, or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit.

Individual Protection Measures

Eye/Face Protection
Wear ANSI- or CSA-approved safety glasses with side shields or goggles. Provide emergency eyewash stations. In extremely dusty environments and unpredictable environments wear un vented or indirectly vented goggles to avoid eye irritation or injury. Contact lenses should NOT be worn when working with Portland cement products.

Skin Protection
Prevention is essential to avoiding potentially severe skin injury. Avoid contact with cement products. If contact occurs, promptly wash affected area with soap and water. In case of severe contact, provide emergency showers. Clothing saturated with wet concrete products should be promptly removed and replaced with clean, dry clothing. Where prolonged exposure to cement products might occur, wear impervious clothing and cut/abrasion resistant (Heavyweight Nitrile coated Safety Cuff) gloves to eliminate skin contact. Where required, wear boots that are impervious to water to eliminate foot and ankle exposure.

Respiratory Protection
Avoid actions that cause dust to become airborne. Use NIOSH-approved respirators (N95 rating or greater) for dust, if an applicable exposure limit is exceeded or when dust levels cause discomfort or irritation.

Acute Toxicity

Chemical Name LC50 LD50 (oral) LD50 (dermal)
Calcium Carbonate 6450 mg/kg (rat)


Skin Corrosion/Irritation
No information was located.
Discomfort or pain cannot be relied upon to alert a person to a hazardous skin exposure. Consequently, the only effective means of avoiding skin injury or illness involves minimizing skin contact, particularly contact with wet cement. Exposed persons may not feel discomfort until hours after the exposure, and significant injury has occurred.

Exposure to dry cement products may cause drying of the skin with consequent mild irritation or more significant effects attributable to aggravation of other conditions. Skin contact with wet or dry cement products may cause more severe skin effects including thickening, cracking or fissuring of the skin. Prolonged skin contact can cause severe chemical burns.

Some ultra-sensitive individuals may exhibit an allergic response upon exposure to cement products, possibly due to trace amounts of chromium (hexavalent chromium salts). The response may appear in a variety of forms ranging from mild rash to severe skin ulcers. Persons already sensitized might react to their first contact with the product; others might experience this effect only after years of contact with cement products. Do not rely solely on barrier creams in place of gloves.

Serious Eye Damage/Irritation
No information was located.
Airborne dust may cause immediate or delayed irritation or inflammation.

STOT (Specific Target Organ Toxicity) – Single Exposure

Mildly toxic.
Although small quantities of dust are not known to be harmful, ill effects are possible if larger quantities are accidentally consumed.

STOT (Specific Target Organ Toxicity) – Repeated Exposure
Risk of injury depends on duration and level of exposure.

Not known to cause cancer.
Key to abbreviations
IARC = International Agency for Research on Cancer. Group 1 = Carcinogenic to humans. ACGIH® = American Conference of Governmental Industrial Hygienists. A1 = Confirmed human carcinogen. NTP = National Toxicology Program.

Other Information
Chromates & Nickel Compounds – Cement products may contain trace amounts of hexavalent chromium and nickel compounds. Soluble chromates in cement have been stated to be the cause of cement dermatitis in some workers. Inorganic nickel compounds – pure or trace amounts – are not absorbed through the skin in amounts sufficient to cause systemic intoxication. However, their capability to cause contact dermatitis in sensitized individuals is well known.

More Information

*To ensure consistent colour and texture throughout a multiple application project, avoid using alternative concrete mixes. It is recommended to complete a small, test-batch when using concrete mixes other than SAKRETE Concrete Mix. To ensure a flowable mix that does not separate when filling forms, and to permit a smooth finish, adjusting the water quantity per batch may be required.
