Asciugo TD

Thermo-insulating and dehumidifying plaster

Premixed dehumidifying plaster, multifunctional, undecomposable, with good thermo-insulating features, anti-condensation, composed by hydraulic bonding agents, selected mineral inerts, fiberglass and constant granulometry (diameter 2mm curve) expanded polystyrene beads, non-toxic, totally CFC and HCFC free, which eliminates molds and condensation formation, being totally free from nutrition for fungi and bacteria.


Fields of application

The product is used for dehumidification, resonation and thermal insulation of walls affected by rising damp. Effectively breaks down thermal bridges and reduces energy consumption, reducing CO2 emissions. Used as plaster to protect facades from rain.

Can be applied both outdoor and indoor, on surfaces composed by:

  • Mixed stone
  • Tuff
  • Bricks
  • Pre-existent masonries affected by rising damp
Support preparation

Substrate must be perfectly solid, free from duest, dirt, failing parts and efflorescences. Clean the surfaces by sanding or sandblasting, then wash with pressurized water to remove any residue.

As thermo-insulating plaster, on crumbling or excessively absorbent surfaces it is recommended to apply a coat of Isoplast 581.

As de-humidifying plaster, remove existing plaster from treated walls by 1 meter from damp marks. In the presence of salt efflorescences, apply SalMur in advance.

It is recommended to apply a 5mm coat of Asciugo Rinzaffo TD in advance, to even the absorption of the support and enhance adhesion of the plaster.

Prepare the vertical guides with the Asciugo TD plaster.

Mixture Preparation

To apply by hand, mix with a cement mixer or a low-rounds stirrer, adding to the content of a 15 Kg bag 10-12 l of clean water (given the nature of the product, it is recommended to mix the content of the bag in one solution). Stir for 5-10 minutes.

To apply via plastering machine, use a elical mixer with solid screw, stator specific for lightweight mortars, long-pitched screws and 14mm diameter nozzle.


Apply a first coat in 1cm thickness and level with a steel spatula. Wait the coat to grip (not less then 4 hours and not more than 24 hours), then apply a second coat in 2cm thickness and level with a trapezoidal aluminum stadia. To add further thickness, repeat the same procedure (Min 3cm – Max 12cm). Once totally cured, proceed with the application of smoothing products and breathable finishes.


Use clean, non-brackish water. Apply between 5°C and 35°C. Do not apply in high sun exposure and on rainy/windy days. Protect from rain, wind, sun and rapid desiccation for 24-48 hours after application. In case of application during summer, ensure a constant desiccation by using Sunshieldings/Windbreakers. Do not add materials, cement or other bonding agents in the bag. It is recommended to mix the entire content of the bag in one solution. It is recommended to wet the substrates the day before application.
