Technical Information
Product Description

Vetotop XT423 is ready to use, liquid-based silicate hardener that works by reaction with free lime present in the concrete to prevent dusting and harden the concrete surface. The product has penetration properties that enable the product to permanently perform across a layer of the concrete surface rather than superficial.

  • Fast, easy to apply.
  • Surface improvement against oils and chemicals.
  • Eliminates surface dusting.
  • Cost-effective.
  • Enhances surface resistance to abrasion.
  • Enhances surface resistance to water penetration.
  • Monolithic, does not add thickness to the concrete surface.
Packaging & Coverage

Vetotop XT423 is supplied in 20 Liters metal buckets.

Yield: 6.5 - 10.0 m2 / liter of liquid for 1 coat.

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


Shelf Life & Storage

The original sealed bucket of Vetotop XT423 has a shelf life of 12 months, provided it is stored clear of ground in a dry and shaded place below 35ºC.

Instructions for use

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 floor's aesthetics.


Ensure that the surface to be treated is fully dry. 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. Use a soft broom or brush.

Allow the solution to be absorbed into the floor for up to 2 hours; remove any solution not absorbed after this period. Failure to do so will result in forming 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 vacuumed dewatered concrete will generally require only a single coat.

If a second application is necessary, re-apply the solution after 24 hours, ensuring that the floor is dry. All surplus solutions must be removed as stated previously. Apply the same procedure for a third application if required.

Surface Preparation

Surfaces to be treated with Vetotop XT423 must be structurally sound and free from loose materials. Repair cracks or holes using a recommended Saveto repair material which should be allowed to cure before proceeding with the application of Vetotop XT423.

Treat oil and grease contaminated surfaces with a suitable chemical de-greaser followed by washing with clean water and allowed to dry.

Remove any laitance or existing coating before application, as these will prevent the Vetotop XT423 from penetrating the concrete surface.

Allow new concrete floors to cure for 14 days before the treatment. Allow the colored floors to cure for 28 days before the treatment. Test a small area with Vetotop XT423 to assess the effect on the color.

Vetotop XT423 must only be applied to dry surfaces to maximize penetration.

Additional Information
Health & Sefety

Vetotop XT423 is alkaline and should not come into contact with skin or eyes or be swallowed.
