NOVABOND THERMO

Substrate preparation:

Cement based substrates must be compact, without cracks, free of dust, salts, grease and any other materials that could reduce adhesion of NOVABOND THERMO to them. Concrete substrates should be mechanically prepared, for example, by grinding to achieve a uniform surface of open porosity. For gypsum-based substrates, it is necessary to prime the substrate with NOVAPRIMER prior to the bonding of the insulating boards. In cases where the application is done upon absorbent substrates such as concrete, cement screeds etc. properly saturate the substrate with water. On surfaces with reduced absorbency, the application of the quartz primer PLANO CONTACT is recommended. For additional information, refer to the relative Technical Data Sheets of the products.

Preparation of the mix:

Mix the contents of a bag of NOVABOND THERMO (25 kg) with 5.5 - 6.0 liters of clean water using an electric mixer at low speed for at least 3 - 5 minutes. The mixing should be done until a homogeneous mixture is achieved. In warm weather conditions and in general, it is advisable not to expose the materials to sunlight (dust and liquids) before use, as this significantly reduces the open application time of the mixture. Wetting the substrate before application is recommended.

Application of the mix:

For flat substrates, apply NOVABOND THERMO directly onto the back of the thermal insulation board using a trowel. Use a notched trowel to spread the adhesive so that it is evenly distributed over the entire surface.

For uneven substrates, apply the adhesive with a trowel in spots at the center and around the perimeter of the thermal insulation board. Apply pressure to place the thermal insulation board in the desired position.

As a smoothing coat, apply the adhesive to the entire surface using a notched trowel and place the alkali-resistant fiberglass mesh NOVATHERM NET onto the wet surface. Embed the mesh in the fresh mixture using the smooth side of the trowel. Apply a second coat after 12 - 24 hours.

Recommendations:

• Do not apply when ambient temperature is less than +5°C or higher than +35°C
• Do not exceed 15 mm of thickness in one single layer
• Do not apply upon metal, wood or deformable surfaces
• Do not apply upon surfaces such as polyurethane coatings, paints, acrylics and substrates subjected to big movements
• Do not apply upon PVC and bitumen membranes and in general materials which polymerize in the long ran
• Do not apply upon loose substrates or substrates not properly cured
• Do not apply upon non-absorbent substrates not properly primed
• Do not apply upon existing expansion or movement joints of the substrate
• Do not apply the mixture under direct sunlight exposure and/or strong wind
• Do not exceed the recommended quantity of mixing water
• Protect the application surface from rain or frost the first 24 hours
• Do not add cement, gypsum, lime or other materials that might affect the properties of the mortar
• The application must be performed by a professional installer

Cleaning:

Tools, buckets, coverings etc. can be cleaned with water as long as NOVABOND THERMO is still fresh. Once the material dries, cleaning can be done only by mechanical means.
