About This Product
No-Rinse Polish Preserver for Worn Stone
HMK® P323 Polish Preserver is a concentrated acrylic stone conditioner that refreshes worn and dulled natural or artificial stone. It develops a brilliant, silky shine during routine care without requiring mechanical polishing, helping tired interior surfaces look cleaner and better maintained.
Protective Acrylic Film for Easier Cleaning
With regular use, P323 develops a protective acrylic film that increases resistance to water and dirt. This added protection makes textured and rough stone surfaces easier to clean while helping floors and other frequently used interior surfaces retain their finished appearance.
Solvent-Free Care for Interior Stone
The solvent-free concentrate supports both initial conditioning and ongoing no-rinse maintenance. It can be applied by cloth, sponge, or mop and may be buffed when a higher shine is desired, providing a flexible stone-care solution for different surfaces and maintenance needs.
Common Questions
Frequently Asked Questions
What is HMK P323 Polish Preserver used for?
HMK P323 is an acrylic maintenance conditioner used to refresh worn or dulled natural and artificial stone. It develops a silky shine and forms a protective film that improves resistance to water and dirt.
What surfaces can HMK P323 be used on?
P323 is suitable for interior natural and artificial stone, including smooth, textured, and rough surfaces. Always test it in an inconspicuous area before treating the complete surface.
Does HMK P323 require mechanical polishing?
No. P323 develops a brilliant, silky shine without mechanical polishing. The dry surface may be buffed with a suitable floor machine and lambswool pad or soft brush when a higher shine is desired.
Does HMK P323 require rinsing?
No. During routine maintenance, do not re-mop or rinse the treated area after application.
Does P323 leave a protective film?
Yes. Regular use develops an acrylic protective film that increases water and dirt resistance while making textured and rough surfaces easier to clean.
Can HMK P323 be used outdoors?
No. HMK P323 Polish Preserver is formulated for interior stone surfaces only.
How should the surface be prepared for the first application?
Switch off any underfloor heating and allow the surface to cool. Clean the stone thoroughly, allow it to dry, and confirm the remaining moisture meets the manufacturer’s 2% to 4% maximum guideline before applying P323.
How is HMK P323 applied for the first time?
Shake the container well and dilute P323 at a ratio of 1:10 with clean water. Apply a thin, even layer using a clean non-fraying cloth, sponge, or mop. More absorbent surfaces may require a more concentrated mixture.
How is P323 used for routine maintenance?
Occasionally add one cup of HMK P323 to one gallon of water. Apply it with a mop, wringing the mop frequently in the same solution. Replace the solution when it becomes dirty, and do not re-mop or rinse the treated area.
How long does HMK P323 take to dry?
Allow approximately 50 to 60 minutes for the surface to dry. Do not walk on the treated area until it is completely dry.
Can P323 be used on floors with underfloor heating?
Yes, but the heating system must be switched off and the surface allowed to cool completely before cleaning or applying the product.
How can the P323 protective film be removed or refreshed?
Use HMK R155 Intensive Cleaner to remove the existing P323 film before refreshing the surface. HMK recommends alternating P323 treatments with P324 Liquid Stone Soap for routine cleaning.
What safety and storage precautions apply?
Keep the product out of reach of children, apply it only between 50°F and 80°F, and store it in a cool location protected from freezing. Test it in an inconspicuous area before completing the application.
