Nida MULTI Task

Instructions for use:

The boards can be joined only after they are fixed durably and stably, according to the mounting rules, when there are no changes in the size of the boards due to humidity or temperature. The room temperature and humidity shall be stabilised. Sudden changes in the room humidity and temperature shall be prevented. The substrate shall be dry, load-bearing, solid enough and free of any impurities. Cut edges and other places on the board where there is no cardboard shall be cleaned of dust, primed, or moistened with water to even out the absorption capacity of the surface. If the above recommendations are not followed, the product may dry faster at the contact of the jointing and skimming compound with the dry plaster inside the board, which could result in cracking. When applied to the entire surface, the substrate shall be cleaned of loose particles, residues of old paint layers and any impurities, e.g. dust, oils or waxes that may limit adhesion and affect the drying of the product. The substrate shall not be wet or frozen. Mould, moss, or fungus deposits shall be removed. Before starting work, the contractor is required to assess the surface and decide whether a primer is needed (on absorbent, loose surfaces, smooth concrete surfaces).
The product shall be applied at an ambient and substrate temperature above 10°C. The ready-mix Nida Multitask jointing and skimming compound has a dry foam consistency and shall be mixed before application. In the case of manual or mechanized application, the product can be diluted with cold, clean water in small quantities (approx. 0.25 l), mixing after each addition of water. A maximum of 0.75 l of clean water can be added to 18 kg of product (for jointing) and a maximum of 1 l of clean water to 18 kg of product (for finishing). No dilution is required for covering corners and screws. Mechanized, the product shall be applied with a No. 531 nozzle. The optimal thickness of one layer is maximum 3 mm, and the next layer shall be applied after the previous one is dried. Drying time approx. 2 to 2.5 h/mm (at a temperature of approx. 25°C / 70% relative humidity). After drying, the jointing and skimming compound shall be sanded with 150-240 grit sandpaper, no later than 3-4 days after application. After this time, the surface becomes hard and strong.

Handling and storage:

The product shall be transported and stored at a temperature of 0°C to 30°C. Keep away from high temperatures or repeated freezing. The packaging shall be kept away from direct sunlight. When frozen, the product shall be left for several hours in a warm room, and then it will be stirred with a mixer at low speed.
Shelf life - 9 months from the date of manufacturing marked on the lid.
