Features & Benefits

• Prosfas is a blend of silicates in water solution with low viscosity and therefore high penetration properties
• It can penetrate to a depth of several centimetres and when dried, it improves the cohesion of cementitious surfaces
• Ready-to-use and need not be diluted
• Customs class: 3823 90 95

Recommendations

• Do not use Prosfas on non-absorbent or wet surfaces
• Do not use on Mapecem or Mapecem Pronto screeds
• Do not use on anhydrite surfaces
• Do not dilute with water or solvents
• Immediately clean up any drops of Prosfas from ceramic tile, glass, marble, and metal surfaces

How to Use

Substrate preparation:

• The substrate must be dry, clean, free of oils, varnish, levelling compounds and other materials which might prevent the Prosfas from penetrating

Application:

• Pour the Prosfas on the surface with a sprinkler or pump and distribute it evenly with a broom, brush, or roller until it is completely absorbed
• Very friable or porous substrates may need more than one coat, in which case wait until the previous coat is dry
• Do not allow pools of excess Prosfas to accumulate because they form a shiny anti-adhesive film
• To prevent the film from forming, sprinkle sand over the last coat of Prosfas and remove the excess sand when dry
• Proceed with levelling or installation of flooring after making sure the surface is dry
• Drying time varies with the amount of product used, and ambient temperature and humidity
• The recommended application temperature is from +5°C to +35°C

Cleaning: 

• Hands, tools and surfaces in contact with Prosfas must be cleaned immediately with abundant water
• Once it hardens, removal is difficult and can only be done mechanically

Consumption:

• Surfaces of screeds can be repaired using 0.5 to 0.7kg/m² of Prosfas but very porous surfaces may require four to six times as much
• Test a small area, especially on very damaged surfaces
• Apply several coats to evaluate how much Prosfas is needed to consolidate the substrates

Storage and Safety Instructions

Storage:

• Prosfas is stable for at least 24 months when stored in a dry place in its original packaging
• Protect from frost

Safety Instructions:

• Prosfas may irritate the skin and breathing system
• Serious damage may be caused if it comes into contact with the eyes
• We recommend the use of suitable protective gloves and protection for the eyes and face
• If the product comes into contact with the eyes, rinse off well with plenty of clean water and seek specialist medical advice
• Hazard classification according to EC 1999/45: Irritant
• Refer to Safety Data Sheet (see 'Data Sheets' section above) before use
