Moeller Stone Care has been cleaning, protecting, and caring for natural stone, ceramic and artificial stone for over 40 years. Our aim is to provide consistent, high-quality products, as well as acting as a support partner for specialist companies in their stone treatment.


HMK® P323 is a concentrated acrylic maintenance conditioner that refreshes worn and dulled natural and artificial stone surfaces. A brilliant silky shine is developed without the need for polishing. The protective film developed with regular use increases water and dirt resistance and makes textured and rough surfaces easier to clean. For interior use only.


Instructions: Ensure that underfloor heating is switched off and the surface is cool. Clean the surface thoroughly and let it dry (max residual moisture of 2-4%). Shake well before use. For first time application, dilute HMK® P323 1:10 with clean water and apply thinly and evenly using a clean non-fraying cloth, sponge or mop. For very absorbent surfaces, use a more concentrated mixture. For regular maintenance occasionally add 1 cup of HMK® P323 for every gallon of water, wringing the mop frequently in the same bucket of solution. Do not re-mop or rinse areas once cleaned. Replace the solution when it becomes dirty. High traffic areas may require more frequent treatments and a more concentrated mixture.


Important: Do not walk on the treated area until dry, about 50-60 minutes. Buff to a higher shine using a regular floor machine (125 rpm) or high speed (1500 rpm) with a lambswool pad or soft brush. Use HMK® P324 Liquid Stone Soap for daily cleaning alternating with HMK® P323 as required. Use HMK® R155 Intensive Cleaner to clean surface thoroughly before first application and to periodically remove the HMK® P323 film and refresh the surface.


Coverage: About 1600 to 2700 square feet pet liter.


Warning: Chemical product. Keep out of the reach of children and safe from frost. Do not use the product in temperatures below 50 and above 80°F.



Storage: Store in a cool place. Do not allow to freeze.


Testing: Always test the product in an inconspicuous area to evaluate suitability, coverage and performance.
