Interior varnish

In order to select a protective coating for your interior flooring or walls, you must first determine the intended use of the surface.
For moderate traffic (stairways, bedrooms, etc.) use Harmony Premium Concrete Sealer, in satin or matte finish.
For heavy traffic (kitchens, showers, work surfaces, stores, etc.), use Harmony Pore Sealant + Harmony Optimum Concrete Sealer, in matte, satin or gloss finish.
For potentially slippery surfaces (patios, exterior stairways, showers), add anti-slip powder to your lacquer.
