Vetoproof EC722

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 a degreaser followed by water or steam cleaning. Mechanical methods like grinding or grit/captive blasting to provide a suitable profiled open textured surface are strongly recommended.

New concrete or cementitious surfaces should be at least 28 days old and have moisture content not exceeding 5%. The old or existing floor should be refurbished mechanically to ensure a clear sound substrate. Repair surface irregularities and blowholes with Vetorep ER350 or Vetorep ER351 (refer to Technical Data Sheet) for application details. Properly treat cracks, expansion joints, and control joints before application. When preparation is complete, ensure to remove dust from the surface using an industrial vacuum.

Vetoproof EC722 does not require a primer. For porous surfaces, apply 1 coat of Vetoprime EP490 at 11 m2/ Liter @ 50 microns DFT.

Add the Hardener (Part B) entire content 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 overcoating with Vetoproof EC722.

Broadcast silica sand on top of Vetoprime EP490 to enhance adhesion of the topcoat.

Vetoproof EC722 is supplied in two preweighed components. Thoroughly stir the contents of the base container. Pour component B hardener into Component A container and mix well with a mechanical jiffy-type mixer operated at low speed. Scrape the side of the container to ensure the entire product has been properly mixed.Remove any excess water using a sponge. Stop any running water with a suitable plugging mortar such as Vetoproof CR747. Contact the local Saveto office for further advice on other suitable water-stopping materials.

After mixing, apply Vetoproof EC722 immediately by short-handed brush, or good quality rollers, or by airless spray to the surface. Ensure a continuous coating of uniform thickness. Apply the second coat as soon as the first coat has dried (within 8-10 hours), depending on the ambient and surface temperatures.

Apply Vetoproof EC722 System at a minimum total dry film thickness of 500 microns.

Apply the coating as a flexible crack bridging wear coat with an anti-slip finish for the parking deck system.

Broadcast graded sand/quartz on the first coat while still wet; allow to dry completely. After overnight drying, brush away the excess sand/quartz, and then apply the second coat.

Remove Vetoproof EC722 from tools and equipment with Vetonit Solvent XX400 immediately after use. Remove hardened material mechanically.

• As with all epoxies, Vetoproof EC722 will yellow when exposed to UV.
• Before filling the tank with water, Vetoproof EC722 must be fully cured for 7days at 20°C.
