Tenaci

Before starting, all substrates must be clean, dry and strong enough to support the weight of the tiles, tile adhesive and grout. Remove all dust, dirt, oil, grease, old adhesive, levelling compounds and paint residues and other contaminants that may affect adhesion.

Remove impairing layers by mechanically brushing, abrading, scabbling or shot blasting. 

Calcium sulphate screeds must be abraded, then vacuumed followed by priming with Validus Para.

The moisture content, when measured by a carbide hygrometer (CM device), must not exceed:

• Cement-based screed on insulation or separating layers in interior areas: 2%

• Calcium sulphate screeds without underfloor heating: 0.5%

• Calcium sulphate screeds with underfloor heating: 0.3%

• Gypsum based plaster: 1%

Validus Tenaci is ready to use. Do not dilute the product.  Stir thoroughly before use. Apply an even thin coat of Validus Tenaci using a roller.

If the substrate is very absorbent or an anhydrite based screed we recommend applying a second coat of Validus Tenaci. When applying a second coat, only do so if the first is dry to touch.

Drying time is approximately 1 hour. On absorbent substrates, tiles, can be laid as soon as the Validus Tenaci is touch dry.  Do not wait more than 24 hours before tile laying.

When applying Validus Tenaci protect areas not to be treated.  Wash off splashes immediately with water. Use on dry substrate only. Do not apply with temperatures lower than 5°C and higher than 40°C.

Coverage:
Approximately 200 gr/m² depending on the absorption of the substrate.

Storage:
The product must be stored in unopened and sealed, in its original packaging in a cool, dry place.

Shelf Life:
Approximately 12 months from the date printed on the side of the packaging.
