Everflex Supaprime

Q: How long must concrete cure before applying Supaprime?

A: Concrete must cure for a minimum of 28 days before it is ready for the application of Supaprime.

Q: What is the pot life of Everflex Supaprime once opened?

A: Everflex Supaprime has a strict 10 to 15-minute pot life due to its rapid moisture-curing nature.

Q: What are the visual and physical indicators that the primer is ready for the next coat?

A: The primer is ready when the film appears translucent and feels tacky to the touch, but is no longer wet.

• Fast drying
• Very low viscosity
• Excellent adhesion to most common porous building materials (preliminary tests suggested)
• Ready to use, Single pack, user-friendly
• Non-corrosive
• Deep penetration into the substrate, providing exceptional adhesion
• Proven long-term durability and resilience
• Suitable for internal & external applications
• Resists mould & mildew in hot and humid environments

Application

Surface Preparation

All surfaces must be structurally sound, stable, dry, clean, and free of dust, loose, flaking, friable material and free from oils, grease, form release agents, curing compounds, and any other surface contamination that may hinder adhesion.

If mechanical preparation is required, prepare the floor using recommended methods, such as dry diamond grinding to provide a roughened, clean, sound, and open porous surface. Thoroughly vacuum loose material and dust. Do not use solvents or acid etching to clean the subfloor. Substrate must be free from surface water and continual dampness.

Concrete must be allowed to cure for at least 28 days. Sand cement screeds to be a 3:1 ratio, and cement render must be allowed to cure for at least 4 days prior to application. Failure to do so may result in poor adhesion and subsequent delamination.

Priming Concrete Surfaces

Apply by brush and/or roller, ensuring the entire area is completely primed. The primer should stay wet on the surface for 2 minutes. Exceptionally porous substrates may require a second coat of Primer 2001. Allow 60 minutes for curing.

Determining Substrate Porosity

To determine whether the substrate is porous or non-porous, dispense water onto the substrate to form a puddle approximately the size of a 1-dollar coin.

• If the water absorbs into the substrate in less than two minutes, the substrate is porous.
• If the puddle remains, the substrate is non-porous.

Limitations

• Do not apply when temperatures are below 10 °C or above 35 °C
• Limited UV resistance (not designed for long-term UV exposure and must be overcoated)
• Do not apply on damp, wet or contaminated substrates, if it is raining or if rain is imminent
• Not suitable for areas subject to hydrostatic pressure or rising damp; Everflex VBS or Megapoxy H is recommended

Health and Safety

First Aid Measures

Inhalation

If fumes or combustion products are inhaled, remove from contaminated area. Lay patient down. Keep warm and rested. Prostheses such as false teeth, which may block airway, should be removed where possible prior to initiating first aid procedures. Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary. Transport to hospital or doctor without delay.

Following uptake by inhalation, move person to an area free from risk of further exposure. Oxygen or artificial respiration should be administered as needed. Asthmatic-type symptoms may develop and may be immediate or delayed up to several hours. Treatment is essentially symptomatic. A physician should be consulted.

Skin Contact

Quickly but gently wipe material off skin with a dry, clean cloth. Immediately remove all contaminated clothing, including footwear. Wash skin and hair with running water. Continue flushing with water until advised to stop by the Poisons Information Centre. Transport to hospital or doctor.

Eye Contact

Wash out immediately with fresh running water. Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. Seek medical attention without delay; if pain persists or recurs seek medical attention. Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.

Ingestion

If swallowed, refer for medical attention where possible without delay. For advice, contact a Poisons Information Centre or a doctor. Urgent hospital treatment is likely to be needed.

In the meantime, qualified first-aid personnel should treat the patient following observation and employing supportive measures as indicated by the patient's condition. If the services of a medical officer or doctor are readily available, the patient should be placed in their care and a copy of the SDS should be provided. Further action will be the responsibility of the medical specialist.

If medical attention is not available on the worksite or surroundings, send the patient to a hospital together with a copy of the SDS. Where medical attention is not immediately available or where the patient is more than 15 minutes from a hospital (unless instructed otherwise):

• Induce vomiting with fingers down the back of the throat ONLY IF CONSCIOUS.
• Lean patient forward or place on left side (head-down position if possible) to maintain open airway and prevent aspiration.
• Wear a protective glove when inducing vomiting by mechanical means.
• Avoid giving milk or oils.
• Avoid giving alcohol.
• If spontaneous vomiting occurs, hold patient's head lower than hips to avoid aspiration.

PPE for First Aiders

Wear rubber boots, overalls, gloves, and a respirator. Use with adequate ventilation. If inhalation risk exists, wear an organic vapour/particulate respirator meeting the requirements of AS/NZS 1715 and AS/NZS 1716.

Available information suggests that gloves made from nitrate should be suitable for intermittent contact; however, due to variations in glove construction and local conditions, the user should make a final assessment.

Always wash your hands before smoking, eating, drinking, or using the toilet. Wash contaminated clothing and other protective equipment before storing or re-using.

Notes to Physician

Treat symptomatically. Effects may be delayed.
