FINE FINISHING PLASTER
Gypsum-based smoothing plaster for interiors.
YESOFIX is used as a smoothing plaster on walls covered with gypsum-based render. It allows to obtain extremely white surfaces and facilitates subsequent painting and decoration work. For damp rooms (bathrooms, kitchens, garages) avoid the use of YESOFIX; it is recommended to use lime and cement based plasters.
The surface must be dry and free of dust, dirt, salt efflorescence, etc. Possible remains of oils, fats, waxes, etc. must be previously removed. For the application of YESOFIX, the plaster must be smooth.
Pour the product into the corresponding amount of clean water (indicated in the Technical Data) and mix by hand or with a mechanical stirrer until obtaining a homogeneous mixture without lumps. The mixture is applied with a metal spatula, with horizontal and vertical strokes. To apply the second coat it is necessary that the first coat is not completely dry. The total application thickness must not exceed 3 mm. After being mixed with water, the mortar must be applied before the workability time indicated in the table has elapsed. The start of hardening depends on the environmental conditions and the absorption power of the support.
