    Allowed supports
    Cement-based or lime-based mortars
    Mixed walls (bricks and stones)
    Stone walls
    Preparation of supports

    Remove the soilings and saline manifestations by vigorous brushing. Then eliminate the residual dust. Saturated with water until you reach the condition of "saturated with dry surface".

    Mode of use

    Apply by spraying, proceeding from the bottom up: it can also be applied with a brush with natural long bristles. In the presence of pronounced degradations proceed with several applications, wet on wet.

    It can cause the opacification of aluminium surfaces, glass, ceramised tiles etc. which must therefore be protected during application. Do not apply on mineral surfaces (plaster, bricks etc.), destined to remain exposed, without carrying out a preliminary test, as there is a risk of latent salt crystallisation. Sanastark is a moderately caustic solution at the implementation stage: do not ingest, wear protective gloves, goggles and clothing, take the necessary precautions.
