Vetotop CS535

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

Vetotop CS535 can be laid as a bonded screed by applying Vetobond PB434 slurry to the prepared concrete substrate as a bonding and priming layer. 

Alternatively, an epoxy bonding agent can be used, such as Vetobond EB430 or Vetobond EB431. 

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 achieving a smooth consistency. Scrub the mixed slurry into the concrete surface. While the slurry is wet, apply Vetotop CS535 to ensure good adhesion with the substrate.

For the mixture’s preparation, pour into a container 6.5-8 liters of water for each 50Kg bag of Vetotop CS535. 

Add the powder to the water and mix with a low-speed electric drill fitted with a suitable paddle until achieving a uniform, lump-free consistency mix. Do not add further water to the mix. Do not add water to the mix once it starts to set. 

Add the required aggregate type to the mixed screed slowly while continuing mixing until a uniform consistency is achieved.

Pour the mixed material onto the surface and spread it to the desired thickness using a steel trowel or suitable tools.

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