Epoxy Polysulphide Elastomeric Coating System
VETOPROOF 722 is a two component polysulphide modified epoxy protective coating system for concrete and steel surfaces consisting of a flexible primer EP722 and a flexible coating EC722. It is specifically developed as lining and waterproofing coating for potable water retaining structures. Its flexibility and ease of application also make it ideal for use as crack sealing coating.
- Vetoproof EP722 is supplied in 4 & 15 Liter Kit - Yield 8-12 m²/Liter @ 100 microns Thickness
- Vetoproof EC722 is supplied in 4 & 15 Liter Kit - Yield 5 m²/ Liter @ 200 microns Thickness
Original sealed bag of Vetoproof 722 has a shelf life of 12 months provided it is stored clear of ground in a tightly closed containers and in sheltered and dry place below 35ºC
The clean and dry surface to be treated with VETOPROOF EC722 should be primed using EP722, a two component solvent free flexible epoxy primer.
Add the entire content of the Hardener (Part B) to the Base (Part A) and mix thoroughly for at least 2 minutes using a drill and spiral mixing head. Apply the mixed material immediately to the substrate, using a medium or short hair roller. The primer should be well scrubbed into the substrate to ensure full coverage. If the substrate is very porous, apply a second coat of primer.
Allow the primer to be tack free before over coating with VETOPROOF EC722.
Broadcasting of silica sand on top of EP722 can be done to enhance adhesion of the top coat.
VETOPROOF EC722 is supplied in two preweighed components. Thoroughly stir the contents of the base can. Pour component B hardener into Component A pail and mix well with a mechanical jiffy.-type mixer operated at low speed. Scrape the side of the pail to ensure the entire product has been properly mixed.
After mixing VETOPROOF EC722 should be immediately applied by short handed brush or good quality rollers or by airless spray, to the surface ensuring a continuous coating of uniform thickness. The second coat can be applied as soon as the first coat has dried (within 8-10 hours), depending on the ambient and surface temperatures.
VETOPROOF CE722 System must be applied at a minimum total dry film thickness of 500 microns.
The coating can be applied as a flexible crack bridging wear coat with an anti slip finish for the parking deck system.
Graded sand/quartz can be broadcasted on the first coat while it is still wet and allowed to dry completely. After overnight drying, the excess sand/quartz can be brushed away and the second coat be applied.
Vetoproof EC722 should be removed from tools and equipment with Vetonit Solvent 1 immediately after use. Hardened material can only be removed mechanically.
The surface should be sound, clean, dry and free from loose and flaking materials, efflorescence, laitance, curing compounds, dirt, oil, grease or other contaminants. Wet substrates should be sponge dried to remove all free surface water, then air dried. Treat oil or grease contamination with degreaser followed by water or steam cleaning. Mechanical methods like grinding or grit/captive blasting in order to provide a suitable profiled open textured surface is strongly recommended.
New concrete or cementitious surfaces should be at least 28 days old and have moisture content not exceeding 5%. Old or existing floor should be refurbished mechanically to ensure clear sound substrate.
Surface irregularities and blow holes shall be repaired with ER350 or ER351 (for application details refer to Technical Data Sheet). Cracks, expansion joint and control joints should be properly addressed, prior to application. After all preparation is complete, ensure dust is removed from the surface using an industrial vacuum.
Steel Surfaces should be grit blasted to surface quality SA 2 1/2. Coat the surface before it starts to oxidize.
The product must be handled with caution. Use gloves, protective creams and goggles to avoid the contact with eyes and skin. All tools used in the preparation and application of VETOPROOF CE722 must be cleaned with VETOSOLVENT XX400 before hardening.
In case of skin contact clean immediately with a resin removing cream, followed by soap and water.
In case of contact with eyes, use clean water to wash the eyes and seek doctor medical attention immediately.
