No, Natural Soap does not enhance waterproofing once the plaster has dried. The crystallization of the soap and lime particles occurs during application while the waterproof plaster is still wet. Once the lime plaster has set, the chemical conditions required for this process are no longer present.

For added water resistance after the plaster has cured, Wax Soap is the best solution. It enhances waterproofing while maintaining the breathability and natural look of the lime plaster.

However, Natural Soap remains an excellent choice for regular cleaning of waterproofed plaster. As a mild agent, it effectively cleans without damaging or deteriorating the lime wall, helping to preserve its finish over time.

Both Artisan Stucco Natural Soap and Waterproof Finish can make your Fresco Stucco waterproof, but they work in different ways. For waterproofing to occur, crystallization must take place, meaning both products need to be applied wet-in-wet onto the Fresco Stucco layer using a finishing trowel.

Natural Soap is a colourless paste that penetrates into the wet Fresco Stucco, providing waterproofing without altering the colour. It can be used with any shade.

Waterproof Finish is a coloured paste that fills open pores in the Fresco Stucco while also adding pigment to the surface. You can match the colour to your base layer for a seamless look or choose a different shade to create special effects and subtle transparencies.
