EVERY FINISH STARTS HERE
HOW TO APPLY
Ensure the plaster surface is fully dry before applying. Allow a minimum of 24 hours after the final coat.
Undiluted: apply a light layer with a plastic trowel, lint-free cloth or paintbrush. Do not over-apply. Diluted (up to 25% lukewarm water): apply with a sponge or lint-free cloth, spreading uniformly. Product appears white but dries clear.
Allow to dry. Remove any excess product with a soft cloth. The natural brightness of the finish will appear as excess is removed.
After approximately 30 min (no more than 2 hours), polish with a clean cloth or polishing machine fitted with wool pads.
- GRASSELLO (polished lime plaster)
- RIVO (satin Venetian Marmorino)
- RIALTO (note: may increase shine -- see below)
- Polished and satin lime plaster finishes
- Exterior surfaces (with penetrating sealer in rain-exposed areas)
- PRIMO STRATO (primer, sealer not applicable)
- Non-lime or synthetic wall coatings
- Designed primarily for gloss and satin lime finishes. Can be applied to RIALTO but may increase surface shine, which is typically at odds with RIALTO's intended matte character.
- For exterior use in areas exposed to rain, SOAPSTONE must be used in combination with a penetrating sealer. SOAPSTONE alone is not sufficient waterproofing for rain-exposed surfaces.
- Product appears white but dries clear. Allow to dry fully before assessing the finish.
- Do not over-apply. Excess product can deepen lighter colors and cause cloudiness in deep or dark colors.
- Protect exterior surfaces from rain for a minimum of 12 hours after application.
- Refer to the SOAPSTONE Safety Data Sheet for full handling, PPE, and disposal requirements.
