Recommended Uses

Residential, commercial, industrial and storage buildings and others.


Coverage

Application Conditions

The temperature of air, mortar and substrate must be at least +5 °C. Working in hot air, strong winds, direct sunlight, rain or before rain should be avoided.


Surface preparation

The substrate to be plastered must be clean and intact. Salt, cement glue, dust and other impurities that weaken adhesion must be removed by using a water sand blaster, for example. A dry substrate must be moistened in advance. However, when the plastering begins, the substrate must be absorbent. On smooth concrete substrates where a net is not used Finnseco Kuitulaasti or Finnseco Ohutrappauslaasti should be used as grout. The surface of a grout layer is combed open using a comb spatula in order to ensure the adhesion of a rough-cast layer. PREPARING THE MORTAR Finnseco Paksurappauslaasti is added to clean water and mechanically mixed to an even mass, after which it is let to water for about 10 minutes before re-mixing and beginning to work.


Painting

First coat:

Grout is applied manually or sprayed tightly onto the substrate so that it covers 90-95% of the area. The grout must harden for at least one day before rough-cast finishing. Spray the rough-cast finish with a plaster pump or apply it manually. The suitable thickness of a single rough-cast layer is around 15 mm. If the layer thickness exceeds 20 mm, casting must be done as several layers. It is recommended to use a metal plastering net attached to the surface on wide areas with layer thickness above 30 mm. A plastering net must also be used on fragile and cracked substrates. The rough-cast surface is leveled using a board and smoothed carefully with a wood float. If the surface is smoothed to a shiny finish, the surface must be torn open with a cross float once it is set. Finnseco Paksurappauslaasti Hieno mortar is used for the plaster finish or troweling of the Finngard Thick Render System when mortar is left on paint surface.
