TB 800 serves for the adhesion and then for the levelling of all types of panels that are usually used for the realization of thermal insulation systems, such as: Styrofoam, polyurethane, wool stone, wool glass, graphite, mineral fibres in brick w , concrete or cement based mortar. TB 800 is a pre-prepared, grey or white, cement-based, Portland material of excellent quality, with carbonate stone sand of selected granulometry, synthetic resins and special additives, which improve the workability, adhesiveness on rough surfaces and increase the hydrophobicity of the strengthened mortar against rains. The levelling of the panels should be made in two layers, combining those with glass- fibres mesh, which is resistant to alkali.

The supports must be compact, seasoned and steady, without cracks, oils, paints or detachable parts. Check to see if the bricks are securely attached and do not have parts that can detach. If there are such parts, remove them and repair surface with mortar. Walls that are coated with grout must be scraped in order to verify if the surface under it was painted with old and badly attached paints, or if there are detachable parts. Powdered surfaces should be treated with primer MEGAGRUND. Superficial cracks can be caulked with TB 800, while deep structural cracks should be treated in a way to eliminate the causes and the possibility of repetition.

Dilute the product Picasso Classic VN-35 with 10-15% water, except for bases D and TR which are recommended to be diluted with not more than 5% water. Use a low speed electric mixer to make the mixture as uniform and complete as possible.

In order to achieve a steady installation, before you start to adhere panels, it is necessary to fix metallic profiles as levelling fasteners. For installations in irregular surfaces, such as unplastered brick walls, the adhesive is applied with a trowel, by putting it as a tape at the edges of the panels, and some drops in its centre (or forming an X in the centre of the panel) in a certain thickness to compensate unevenness. For applications in flat surfaces, it is recommended to spread the adhesive in the entire surface of the panel through e notched trowel (from 8 up to 10 mm). Caution must be paid to the surface covered with adhesive, which should be at least 40 % of the total panel surface. Panels should be installed in horizontal direction, starting from the bottom and continuing up. Caution to the panels' joints; do not leave empty spaces or unevenness. Then, proceed with the mechanic fixation of wall anchors (for usual panels 50 x 100 cm, it is recommended to pour 8 adhesive drops for meter square). The above data are applicable in temperatures from (23 ±2°C) and in (50 ±5) % relative humidity. Lower temperatures prolong the time of maturity and solidifying.

12 months, if stored in normal environments and in its original packaging, protected from direct exposure to the sun and frost.
