Premixed 20 to 100 mm thick cementitious bonded screed.
Vetotop CS537 is a single component cementitious bonded floor screed composed of hydraulic binders, silica sand, selected aggregates, and special additives. It is supplied as a dry powder in pre-weighed bags ready to use on-site, once mixed it will form a screed-able trowellable mortar that is applied in thicknesses between 20 and 100 mm.
50 Kg Bag
21.7 - 27.8 Ltr
An original sealed bag of Vetotop CS537 has a shelf life of 12 months provided it is stored clear of ground in a dry and shaded place below 35ºC.
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.
Product Data Sheet
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.
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.
