Instructions for use

  1. Check that the application surface is suitable and ready for use.
  2. Moisten surfaces before applying the product.
  3. Use of 4.7-5 liters of clean water in an electric mixer at low rpm until you obtain a smooth, lump-free paste.
  4. Leave the paste to stand for 2 minutes and mix again before applying.
  5. Spread over the surface in thickness not exceeding 5 mm.
  6. Once the mortar has started to harden, smoothed with a plastic or wood trowel.
  7. Moisten the mortar 24 hours after application. Repeat for 2 to 3 days.
Warnings and recommendations
  • Do not cover the surface of TX cement mortars, as it could affect its depolluting properties.
  • Do not apply directly to the enclosure (brick, concrete block, etc.).
  • Do not apply onto plaster surfaces.
  • Do not apply this product when frost or rain are forecasted.
  • Do not apply at temperatures below 5 ºC or above 35 ºC.
  • Do not apply onto smooth or non porous water repellent surfaces.
  • It is advisable to moisten absorbent or very hot surfaces before applying the product and 24 hours afterwards in order to prevent the mortar from becoming overly dry or less strong.
  • Use aplicaRev Fix as an adhesive bridge on concrete and on smooth or non porous surfaces.
  • This product is ready to mix with water. Do not add any kind of additional substance which may alter its properties.

Technical Features

Available Formats

Capafina TX Descontaminante is available in 25 kg paper sacks with moisture-proof plastic lining, dispatched on shrink-wrapped pallets weighing a total of 1,000 kg (40 sacks).

Application Surfaces
  • Stable and healthy mortar renderings with a proper absorption, roughness, flatness and strength.
  • Check that the application surface is suitably flat. Ensure that there is no dust, disintegrating parts, remains of plaster, paint and surface water repellents that avoid proper placing and anchoring.

Photocatalytic cements, incorporating the active principle TX, in the presence of light transform permanently air pollutant substances into gases or salts that have no impact on the environment and on people’s health. By action of the photocatalytic effect, gaseous pollutants are trapped on the surface of TX cement mortars. Thereafter, oxidation-reduction reactions become harmful gaseous substances, eliminating air pollution agents.

Depolluting mortar, produced from TX cements can reduce by 20% and 80%, depending on weather conditions and light, harmful substances produced by human activity such as nitrogen oxides (NOx), sulfur oxides (SOx), NHX (gas), volatile organic compounds or VOCs (benzene, toluene…), fine particulate (PM10, PM2,5) and other… Capafina TX Descontaminante has been designed specifically for the performance of façade finishes, able to actively contribute to reducing air pollution.
