What homeowners ask about Rob Parker’s Best Conclear

Rob Parker’s Best Conclear is a stone consolidator. Instead of coating the surface like a sealer, it penetrates deep into natural stone and strengthens it from within.

It’s designed to:

• Stabilise fragile or weathered paving
• Prevent further crumbling or erosion
• Help soft stone last longer outdoors

Conclear is most useful on stone that’s already showing signs of wear — like flaking, chalky residue, or softness underfoot. It’s commonly used before sealing to make sure the stone can handle traffic, cleaning, and weather exposure.

If sealing is your protection layer, Conclear is the foundation that stops the stone from falling apart underneath.

It depends on the condition of your stone.

If the surface is stable, solid, and hasn’t started breaking down, a patio sealer is likely all you need. But if the stone is already flaking, dusty, or very soft, it’s best to use Conclear first to give it internal strength — and then seal it once stable.

Conclear is often needed before sealing on:

• Older patios with visible surface wear
• Soft limestones or sandstones
• Fragile coping or pool edging stones

Sealing without consolidation first can trap weakness inside the stone, causing more damage long-term.

Yes — that’s exactly what Rob Parker’s Best Conclear is for.

When stone begins to break down, sealing alone won’t help. If the surface is already unstable, applying a sealer might even trap moisture or pull more material away. Conclear soaks into the stone and stabilises it from the inside, helping to stop further damage.

You should apply it before any cleaning or sealing if:

• The stone is crumbling underfoot
• It leaves chalky dust behind when swept
• You can scrape it easily with your fingernail

Once Conclear has cured, the surface will be much stronger and ready for sealing or light maintenance.

No — Conclear isn’t a waterproofing treatment.

Its job is to reinforce the structure of the stone, not to repel water from the surface. It may slightly reduce absorption by tightening up the internal structure, but you’ll still need a proper sealer if you want to stop:

• Water soaking into the top
• Algae or moss forming in damp spots
• Staining from organic material

Once Conclear has cured, you can apply Rob Parker’s Best Invisible Sealer or Colour Enhancer for full surface protection.

Yes — if your stone is fragile or crumbling, Conclear should always go on first.

It needs to penetrate deep into the stone to be effective. If you seal first, you’ll block that absorption and prevent Conclear from working. Once cured, the surface will be ready for a protective sealer.

Steps:

1. Clean and dry the area
2. Apply Conclear to strengthen the stone
3. Wait 24–48 hours
4. Apply your sealer of choice

Yes — Conclear is completely safe for use around pool edges, steps, driveways, paths, or patios.

It’s especially useful on:

• Soft limestone coping stones
• Weathered sandstone near water
• Driveway paving that’s starting to break apart

But remember, it won’t:

• Repel pool chemicals or car oil
• Add any anti-slip properties
• Replace the need for a sealer

It’s meant to stabilise the structure, not replace top-layer protection.

One full application of Conclear typically lasts for many years. Because it works internally, it doesn’t wear away like a surface sealer.

You’ll only need to reapply it if:

• The stone is extremely porous and absorbs a lot first time
• It suffers new damage (from frost or heavy cleaning)
• You’re re-treating repaired areas or patches years later

For most homeowners, one thorough treatment is enough — especially when followed by sealing.

Conclear is ideal for use on porous, natural stone that’s prone to surface wear. It’s especially effective on:

• Limestone
• Sandstone
• Travertine
• Soft marbles
• Other soft or flaky flagstones

Avoid using it on porcelain, granite, or engineered paving — these are too dense and don’t need internal consolidation.

If your paving absorbs water quickly, dusts when dry, or has an uneven surface texture, it’s likely a good match for Conclear.

Yes — Conclear is safe and effective indoors, too.

If you have original limestone or sandstone flooring, indoor flagstones, or heritage stonework that’s becoming dusty or worn, Conclear can stabilise it without changing its appearance.

It’s perfect for:

• Hallways and kitchen stone floors
• Old cottage interiors
• Stair treads and thresholds

It won’t add any gloss, leave residue, or alter colour — so it’s ideal for preserving the original character of stone in listed buildings or period homes.
