Application Information
Surface Preparation

Surface Preparation

The surface should be sound, clean, free from loose material, grease, laitance, dirt curing compound, etc.


Vetotop CS537 is a bonded screed that can be laid in thickness between 20 - 100 mm.

For more adhesion, an epoxy bonding agent can be used such as Vetobond EB430 or Vetobond EB431. Vetobond PB434 slurry can also be used.

To prepare the slurry primer mix 1 volume of Vetobond PB434 to 1 volume of clean water with 3 volumes of fresh cement and mix until a smooth consistency is achieved. Scrub the mixed slurry into the concrete surface, while the slurry is wet apply Vetotop CS537 in order to ensure good adhesion with the substrate.

Stated consumptions data are for general guidance. Actual consumption depends on the nature of the substrate, method of application and wastage.



For mixture preparation, pour into a container 4.5-5 liters of water for 50 Kg bag of Vetotop CS537.

Add the powder to the water and mix with a low speed electric drill fitted with a suitable paddle, until   a uniform, lump free consistency mix is achieved. No further water should be added to the mix. Do not add water to the mix once it starts to set.


Pour the mixed product onto the surface and spread to the desired thickness using steel trowel or suitable tools. Cover the screed with a plastic sheet to avoid drying.

Cure the screed as per standard concrete curing practices. Do not subject the screed to vehicular traffic for 28 days till ensure full cure and systems ability to withstand designed traffic loads.

A concrete sealer is required for enhancing the screed durability and resistance to ingress of water, apply Vetoseal XW770 at a rate of 8 to 12 m2 per liter. Make sure that the sealer is uniformly applied and covering all screed surface.


Clean tools with water promptly before material hardens. Hardened material can be mechanically removed.

  • Do not apply the product at a temperature of less than +5ºC.
  • Vetotop CS537 should be checked for its suitability when concrete is steam cured. Also, carry out prior tests for its suitability when gypsum or colored mixes are being used.
