Installation Guidelines

Do it once. Do it right — the RMS Stonex way.

1) Preparation

A flawless finish starts with a perfect base.

  • Surface must be clean, level, dry, and structurally sound.
  • Floor flatness target: ≤ 3 mm deviation over 2 m; correct with self-leveling compound.
  • Dry-lay key veins; plan cuts and 2–3 mm grout joints for consistency.

2) Selecting the Right Adhesive

Use stone-safe, non-staining products.

  • Natural-stone rated polymer-modified thinset; white for light marbles.
  • Wet areas: choose water-resistant, anti-sag formulations.
  • Large formats: back-butter tiles/slabs; achieve ≥ 95% coverage.

3) Professional Installation

Precision handling prevents micro-cracks and edge damage.

  • Use lifting clamps/suction cups; avoid levering edges.
  • Experienced crew for cutting, profiling, and movement joints.

4) Sealing the Marble

Invisible protection, long-term peace of mind.

  • Apply a high-quality impregnating sealer after cure (usually 24–72h).
  • Reapply every 6–12 months depending on porosity and traffic.

Substrate & Environment Checklist

  • Concrete cured (≈ 28 days) and within adhesive moisture tolerance.
  • Wood subfloors stiffened; deflection controlled; suitable underlayment.
  • Movement joints at perimeters, doorways, and every 6–8 m spans.
  • Ambient temperature 10–32 °C; avoid rapid drying & direct sun during set.

Grout & Finishing

  • Use non-sand (or very fine sand) grout for polished marble.
  • Clean grout haze promptly with pH-neutral removers.
  • Final buffing; apply initial seal after grout has cured.

Common Pitfalls to Avoid

  • Dark/grey adhesives under white marble (risk of shadowing).
  • Skipping movement joints (leads to tenting/cracks).
  • Acidic cleaners (cause etching and dull spots).

Maintenance & Care

Simple daily habits that preserve the shine and protect your marble for decades.

Cleaning
  • Use a soft cloth and pH-neutral stone cleaner.
  • Blot spills immediately — avoid rubbing to prevent spread.
  • Weekly: damp wipe; Monthly: deeper clean; Avoid steam on polished surfaces.
Resealing
  • Water-drop test: if it darkens quickly, it’s time to reseal.
  • Typical schedule: every 6–12 months (higher traffic = sooner).
  • Use an impregnating sealer; follow dwell time and buff residue.
Scratch & Etch Prevention
  • Use coasters, trivets, felt pads; never drag heavy items.
  • Avoid acidic agents (vinegar, lemon, cola); use chopping boards.
  • For minor etches, consult a professional polish before DIY abrasives.
Temperature & Humidity
  • Ventilate baths; control humidity to prevent moisture issues.
  • Use trivets — avoid placing hot cookware directly on marble.
Stain Handling
  • Wipe spills fast (coffee, wine, citrus, oil).
  • For stains, apply a mild poultice; re-seal area after cleaning.
Routine Schedule
  • Daily: wipe & spot clean • Weekly: damp clean • Quarterly: audit & top-up seal.
  • Annual: full inspection; professional polish if surface dulls.

Do

  • Use pH-neutral cleaners Prevents etching and dull spots.
  • Blot spills immediately Reduces absorption and staining.
  • Use coasters, trivets, and felt pads Protects from heat and scratches.
  • Test for resealing every 6–12 months Maintains stain resistance.

Don’t

  • Use vinegar, lemon, or bleach Acids/harsh alkalis cause etching.
  • Drag appliances or furniture Creates scratches & edge chips.
  • Place hot pans directly on marble Thermal shock and rings.
  • Skip movement joints or sealing Leads to cracks and stains.

Stain Removal • Quick Guide

Identify the stain type and use the right poultice. Always test in an inconspicuous area first.

Coffee / Tea
Type

Solution
Hydrogen peroxide (6–12%) + talc (or kaolin) poultice
Dwell
6–12 hrs (light); up to 24 hrs (deep)
Steps Blot → pH-neutral clean → mix peroxide + powder to peanut-butter paste → apply 5–8 mm thick → cover with cling film, perforate → wait → remove, rinse, dry → repeat if needed.
Wine / Juice
Type
Organic (acidic)
Solution
Hydrogen peroxide poultice; neutralize with pH-neutral cleaner after
Dwell
12–24 hrs
Steps Rinse → apply peroxide poultice → cover & dwell → remove → rinse well → reseal if water darkens fast.
Oil / Grease
Type
Petroleum / Organic
Solution
Acetone or mineral spirits + talc poultice (use with ventilation)
Dwell
12–24 hrs (repeat for heavy oil)
Steps Degrease lightly → apply solvent poultice → cover & dwell → remove → pH-neutral clean → dry 24h → reseal.
Rust
Type
Metallic
Solution
Stone-safe rust remover (non-acidic) or oxalic-acid based product for marble
Dwell
As per product (usually minutes, not hours)
Steps Mask surrounding area → apply per label → light agitation with soft pad → rinse thoroughly → neutral pH wash → dry.

FAQ — Installation & Care

Your most common questions about adhesives, sealing, cleaning, and long-term care—answered by RMS Stonex.

Which adhesive is best for marble?

Use a natural-stone rated, polymer-modified thinset/adhesive. For light or white stones, choose white adhesive to avoid shadowing. In wet zones, pick water-resistant, anti-sag formulas.

Target ≥ 95% coverage and back-butter large formats.
How often should I seal marble?

Typically every 6–12 months, depending on porosity and foot traffic. Kitchen counters and bathrooms may need more frequent sealing.

Water-drop test: Sprinkle a few drops—if darkening is quick, it’s time to reseal.

Which cleaner should I use daily?

Use a pH-neutral stone cleaner with a soft cloth. Avoid vinegar, lemon, bleach, or abrasive powders—they cause etching or micro-scratches.

What’s the difference between a stain and an etch?

Stain: discoloration absorbed into stone (e.g., oil, coffee). Solve with the correct poultice.

Etch: a dull spot from acids reacting with marble. Not a stain—needs polishing powder or pro honing.

What grout should I use with polished marble?

Prefer unsanded or very fine sanded grout to minimize scratching. Clean grout haze promptly with pH-neutral remover.

Is marble okay with hot utensils or underfloor heating?

Use trivets—don’t place hot cookware directly on marble to avoid thermal shock/rings.

Underfloor heating is fine if proper movement joints & flexible adhesives are used; follow manufacturer temperature limits.

Can I install marble in bathrooms and kitchens?

Yes—use water-resistant adhesives, ensure proper sealing, and maintain good ventilation. For kitchens, wipe spills quickly and reseal more often.

What grout joint size do you recommend?

Commonly 2–3 mm for tiles; large formats may vary based on flatness and layout. Always dry-lay to balance veining and joint lines.

How do I remove a coffee or oil stain?

Use a poultice: absorbent powder (talc/kaolin) + appropriate liquid—peroxide for organic stains; acetone/mineral spirits for oil.

Apply 5–8 mm thick, cover, dwell (8–24h), then rinse and dry. Repeat if needed; reseal area after.

Do you offer site visits or installer recommendations?

Yes. We can connect you with experienced installers in your city and schedule a site assessment. Share your location, area (sqft), and timeline.
