Single component penetrating waterproofing system for concrete
VETOPROOF CM741 provides total and permanent waterproofing solution to water leakage, ingress or seepage in concrete structures or any cementitious substrates due its unique, surface applied penetrative capillary water proofing system. VETOPROOF CM741 works through internal crystallization that seals the pores and hairline cracks in the concretes thus blocking effectively further passage of water. The active chemical that made up VETOPROOF CM741 serves as a catalyst to reactivate crystallization process every time water penetrates into the structure through newly formed capillaries therefore ensuring permanent water tightness.
- Non-toxic and does not contain any momentary organic components
- Excellent resistance to freeze-thaw cycles
- Can be applied even on humid surface
- Guarantees permanent water sealing of concrete
- Can be applied on all structurally sound concrete whether old or new
- Active components present in the watertight concrete reactivates upon impact with water
- Treated concrete are completely watertight after 5 days
- Highly resistant to deicing salts, sulphuric acid and hydrochloric acid during at least 35 days
- Shields concrete and reinforcement from corrosion due to water
- ASTM D4799
- ASTM E96
- ASTM D4060

Application
In the event that the use of masonry brush is the method for application, mix 7 - 7.5 liters of water with 25 kg of Vetoproof CM741, while when a power spray gun is being used, prepare a mixture of 8 – 8.5 liters of water with 25 kg of the product. Mix only as much product as necessary and ensure to stir the mixture regularly. In the event that the mixture starts to set, it is not advisable to add more water, instead simply re-stir the prepared mixture in order to reinstate its workability. Apply Vetoproof CM741 into two coats with the use of a masonry brush or power spray gun. Make sure to apply the second coat while the first coat is still “green”. All areas where Vetoproof CM741 is applied should be kept damp, protected against direct exposure from sunlight, wind and frost by covering the area with polythene sheeting, damp hessian cloth etc. for a period of 5-7 days. Ensure that the period between the application of the first and second layer is between 3 – 4 hours at a temperature of 20°C.
Cleaning
All tools employed for the application of Vetoproof CM741 can be cleaned with water before it hardens otherwise mechanical means are needed.
All surfaces where Vetoproof CM741 has to be applied must be clean and have an open capillary system. Eliminate laitance, dirt, grease and other loose materials by means of high pressure water jetting or wet sand blasting. Defective concretes such as cracks and honeycombs, etc. has to be chased out and repaired prior to the application. In addition, make sure that all surfaces must be damp but not totally wet before progressing the work.
Do not apply Vetoproof CM741 on temperatures below 5°C.
Vetoproof CM741 could not be used as anadditive to concrete or plasters.
Vetoproof CM741 contains cement powders which, when mixed or become damp, release alkalies which can be harmful to the skin. During use, avoid inhalation of dust and contact with skin and eyes. Wear suitable protective clothing, gloves, eye protection and respiratory protective equipment. The use of barrier creams provide additional skin protection. In case of contact with skin, rinse with plenty of clean water, then cleanse with soap and water. In case of contact with eye, rinse immediately with plenty of clean water and seek medical advice. If swallowed, seek medical attention immediately – do not induce vomiting.
Vetoproof CR747 is non-flammable.
