Ensure that the outside temperature and the temperature of the surface being treated do not fall below +5°C during application and drying. Protect from weather conditions that might prevent the product from drying correctly, such as rain, wind, frost or direct sunlight. The product can be stored in a dry place for up to 12 months, pursuant to Annex XVII of Directive 1907/2006/EC, at 20°C and with a relative humidity level of 65%. Packaging date on the packaging.

This is the second phase, after rough coating, of a repair system for masonry with damp and/or salt problems
Suitable for treating old and new external walls of buildings, but also internal walls in cellars, basements etc. that are exposed to rising damp
Preparation of surfaces:
Identify precisely which area of the masonry is affected by rising damp, salt formations and any mould. Remove all plaster layers up to 1 metre above the edge of the damaged masonry area. Scrape the joints to a depth of approximately 2 cm. Immediately dispose of the removed material: the salts that had saturated the old plaster might seep back into the soil in case of rain. Prepare the substrate so that it is solid, substantial, as dry as possible, free of dust and any chemical materials or compounds (such as release agents). If it is necessary to improve the adhesion or adjust the degree of absorption of the substrate, apply a rough coat to approximately 60% of the surface using Würth Rinnova D Rough Coat
Preparation of the mixture:
Mix one sackful of RINNOVA D PLASTER (25 kg) with 6.25 litres of clean water, using a suitable mixer, for as long as it takes to obtain a uniform mixture. The mixing should be done at low speed in order to promote the incorporation of air. The mixing time for manual mixing is 2 to 3 minutes. Avoid longer times because this would degrade the consistency of the plaster. Once the material has set, it must not be mixed again
Wait for the rough coat to set, if previously applied. Apply Rinnova D Plaster using a trowel, then smooth it over with an aluminium straight edge. Alternatively, the product can also be worked by machine using a plastering machine with a suitable shaft mixer and auger, as well as a secondary mixer. The waiting time between one coat of plaster and the next is 1 day per mm thickness applied. Before applying a coat to a refurbishment plaster, the refurbishment plaster must be completely dry. The fresh mortar is only workable within the first 2 hours. When applying several coats, apply in minimum thicknesses of 20–25 mm per coat. For better adhesion, immediately roughen each coat horizontally before it is fully set. The application of the plaster will be 40% in direct contact with the masonry, and 60% covering the substrate treated with rough coat. All coatings, whether finishings or paints, must comply with the WTA directive. Unsuitable coatings, e.g. non-breathable, could compromise the effectiveness of the repair system. In very damp conditions or where there is salt contamination (see classification in ÖNORM B3355-1) or very thick plaster, at least two or more coats should be applied
