Design Criteria

Vetotop XT423 is designed to be a permanent surface hardener and dust-proofer. Vetotop XT423 in liquid solution penetrates the concrete surface layer and reacts with concretes free lime to permanently seal pores and harden the surface. It is important to follow the usage instructions and wash the treated surface with plenty of water within an hour of application to prevent permanent surface crystallization that disturbs the aesthetics of the floor.

Application

Ensure that the surface to be treated is dry and apply the mixed Vetotop XT423 at a rate of approximately 1 liter to every 6.5-10 m2 depends on the surface condition and concrete porosity  using soft broom or brush.

Allow the solution to be absorbed into the floor for a period of up to 2 hours, any solution not absorbed after this period should be removed. Failure to do so will result in the formation of a weak, glossy surface film following the drying.

Normally a two or three coat application is recommended for complete treatment, however, very dense, well trowelled surfaces such as granolithic
toppings, power floated or vacuum dewatered concrete will generally require only a single coat. If a second application is necessary, reapply the solution after 24 hours ensuring that the floor is dry. All surplus solution must be removed as stated previously. The same procedure will apply for a third application if required.
