Ecologic Lime Plaster TOPCOAT Platinum is a structural, breathable lime mortar that can be used for everything from interior plastering to exterior stucco work (lime render) to parge coats. It can even be used as a general lime mortar for repointing historic brick and stone and for laying up new masonry units, wether they receive a lime render overtop or not.
Ecologic TOPCOAT Platinum can also be applied over a base coat of Ecologic TAKCOAT Platinum when transitioning from smooth substrates that offer no mechanical key, such as new or painted drywall, magnesium board, Dense-glass®, or soundly painted masonry.
TOPCOAT Platinum is a pre-blended dry powder based on hydraulic lime and aggregate, and it contains no Portland Cement and no VOCs.
Mixes differ according to application
Type G is a diverse, coarse-sanded mix that can be used as the base coat placed directly over porous and stable raw masonry, or over non-rusting lath for framed walls, or as the leveling “brown coat” in a three-coat plaster/stucco system. It can also then be used as the final, coarse-textured topcoat, as the name implies. Since TOPCOATPlatinum Type G is composed of Hydraulic Lime and aggregates it is almost universal and serves many purposes.
Type F is a diverse, fine-sanded mix that can not only be used as the final, fine-textured topcoat for plaster and stucco, but it can also be used as lime mortar for repointing narrow brick and stone joints, ⅜" wide and under.
Type XF is an extra-fine-sanded mix that is used as a final finish coat of interior lime plaster.
The coverage of a 50 Lb bag of TOPCOAT Platinum will vary depending on the thickness of the coat of material applied.
