Tenax Proseal (Stone Sealer)

₱4,600 per sqm

The commonest thing to land on a kitchen worktop is a fine spray of oil off a hot pan. Tenax Proseal (Stone Sealer) keeps oil and water both out of the stone, and it does it without adding gloss or shifting the color.

Why Choose Tenax Proseal (Stone Sealer)

Oil and Water Together A kitchen needs both held out. A water-only sealer leaves cooking oil a clear run into the pores.
Absorbed, Not Coated An impregnating sealer coats the pore from within, so nothing sits on top waiting to wear thin, peel or cloud over.
Leaves the Look Alone No gloss, no darkening, no sheen. A properly sealed counter is indistinguishable from a bare one.
The Bottle We Reach For Our first pick on kitchen counters in Laguna, where cooking oil and daily spills ask the most of a stone.

What Is Tenax Proseal?

An impregnating sealer that goes into the stone rather than over it.

Tenax Proseal is a solvent-based impregnating sealer for natural stone, produced by Tenax in Italy. It holds back oil and water alike, and that is the line between it and a water-only bottle.

Impregnating is the operative word. Proseal is drawn into the pore structure and coats those pores from within; it never cures into a skin. Nothing is left lying on top to wear thin or peel away.

Which is why a sealed worktop still feels like stone under your hand. You have not added a layer. You have taught the pores to shed liquid instead of drinking it.

Every counter we install is sealed with Proseal, and this is the bottle to buy when the time comes to redo it. Walls, flooring and outdoor stone want Tenax Hydrex instead, and both are stocked at our Laguna branch.

Which Stones Need Sealing?

Not the ones most people guess. Color predicts nothing at all.

This is the misunderstanding we untangle most often. How readily a stone absorbs varies slab by slab, and it has no relationship to how pale or how dark that slab looks.

Wants sealing

Most granites, Salt and Pepper, River White, Paradiso Dark, Gray Honda and Black Impala among them. Add every marble and every onyx we bring in.

Wants nothing whatsoever

All engineered quartz, no exceptions, because the resin binder leaves a sealer nowhere to sink into. Among the granites, Absolute Black, Black Galaxy, Tan Brown and Marigold.

Why the shortcut fails

Marigold reads light brown and asks for nothing. Salt and Pepper and River White are pale and both want sealing. Gray Honda and Paradiso Dark are dark and want it too. Anyone who tells you dark stone never needs a sealer, without first asking which stone, has not looked.

Settling it on your own counter

Put a few drops of water somewhere out of sight and leave them about fifteen minutes. Darkening underneath means the stone is drinking and wants sealing. Beads that wipe away clean mean you can leave it be.

How Do You Apply Tenax Proseal?

Three steps, and the last one gets skipped most.

1

Dry Stone, Not Just Clean Stone

A pore already holding water has no room for sealer, so the slab has to be bone dry. Wash it with a pH-neutral stone cleaner and then give it several hours before you start.

2

Thin Coat, Then Let It Sink

Lay a thin even film on with a cloth or an applicator pad and let it soak for the time the bottle states. Break the counter into sections so nothing dries out before you get back to it.

3

Lift Off Every Trace of Excess

Take the surplus back off with a clean dry cloth before it sets. Whatever stays behind hardens into a cloudy patch, and that haze is what almost every complaint about sealing turns out to be. Keep the air moving while you work.

Proseal shares a shelf with the rest of our stone care products at the Sta. Rosa, Laguna branch, alongside the cleaners that will not strip it off again.

Does Sealing Change How the Stone Looks?

No, as long as you lift the excess off.

No. Because it works below the surface, Proseal adds no skin, no gloss and no shift in tone. A properly sealed counter is indistinguishable from an unsealed one.

Residue is the exception. Sealer left to dry on top rather than buffed away sets into a patchy bloom, and on a dark polished granite it shows badly. That is an application fault and not a property of the product.

Where a counter has been hazed that way, the Sta. Rosa branch can talk you through stripping it back, though buffing properly the first time is very much the easier route.

Proseal is not a polish and puts no shine on anything. For gloss on natural stone, Stone Care Granite & Stone Polish is the bottle for that separate job.

Does Sealing Prevent Etching?

No, and this one catches people out badly.

No. Sealing keeps liquid from being absorbed. It has no effect at all on acid biting chemically into the surface, and those are two entirely separate kinds of damage.

A stain is color left behind by something that soaked in. An etch is a dull scar where acid has eaten the polish itself. Calamansi, vinegar and wine will dull a marble through a flawless seal.

Which bears hardest on the calcium carbonate stones, meaning every marble and every onyx. Sealing those is still worth doing, and it will still not rescue the surface from a glass of red left standing overnight.

Granite is a silicate rather than a carbonate and does not etch, so on granite a seal does cover the main risk. Quartz neither etches nor absorbs, which is why no sealer belongs on it.

Proseal vs Our Other Stone Care Products

Four bottles, four separate jobs.

Proseal is the countertop sealer

Oil and water held out, at ₱4,600. Kitchen counters, vanity tops and anywhere food and cooking oil turn up. This is the one that goes on at installation.

Hydrex covers walls, floors and outdoors

Tenax Hydrex at ₱3,500 guards against water rather than oil, which suits cladding, flooring and pool decks, where rain and damp are the threat and cooking oil never appears.

Cera Fluida is wax, not a sealer

Tenax Cera Fluida, also ₱3,500, deepens color and lays on a soft sheen. It rides on the surface and wears away, so it is a finish rather than a defence. Keep it off quartz, where wax turns yellow.

Solido is glue

Tenax Solido from ₱1,600 is a polyester mastic for bonding and patching stone, in black, white and transparent. Listed because the names run together at the counter. All four are on the shelf at our Sta. Rosa, Laguna yard.

How Often Should You Reseal?

Whenever the water test fails, never on a date in the diary.

1

Let Water Decide

Put a few drops on a spot nobody looks at, leave them about fifteen minutes, then wipe. A darkened patch underneath means the sealer has given out; water still standing in beads means it is holding. Marble and onyx can reach that point inside six months, while a granite that needs sealing at all will often manage a year.

2

Test Where the Counter Works Hardest

The sink surround and the strip beside the hob give out first, because that is where water pools and oil lands. A counter can want resealing at the sink while the far end is still perfectly sound.

3

Do Not Reseal Out of Habit

Sealer beyond what the stone can take simply dries on top and hazes. Working to a schedule instead of a test is exactly how counters end up cloudy.

Frequently Asked Questions

How do I know if my counter needs sealing?
Leave a few drops of water somewhere out of sight for about fifteen minutes. Darkening underneath means it wants sealing. Beads that wipe away without a mark mean the seal is holding. The test works on any natural stone.

How is Proseal different from Hydrex?
Proseal holds out oil and water, at ₱4,600, and is the countertop choice. Hydrex holds out water alone, at ₱3,500, for walls, flooring and outdoor stone. Oil is the harder problem in a kitchen, so counters get Proseal.

Will sealing stop my marble etching?
No. Sealing prevents absorption, not chemical attack. Acid still dulls the polish on marble and onyx through a flawless seal. Keeping calamansi, vinegar and wine off those surfaces is the only real defence.

Does engineered quartz need sealing?
Never. The resin binder leaves a sealer nothing to sink into, so it simply dries on top as a film. Anyone selling you sealer for a quartz counter has not asked what the counter is made of.

Can I apply it myself?
Yes. Wipe on, wait, wipe off, and an evening covers it. The step that decides the result is taking off every trace of surplus before it sets, since residue hardens into a haze.

What happens if I leave residue on the surface?
It dries into a blotchy, cloudy film that shows up plainly on dark polished stone. It can be put right, but stripping it back is more work than buffing properly at the time.

Will it take out a stain that is already there?
No, and sealing over a stain traps it. Draw it out with a poultice first, let the stone dry right through, then seal. The Laguna branch can point you to the right poultice for the mark.

Where can you buy Tenax Proseal in Laguna?
Stone Depot keeps Tenax Proseal at ₱4,600, on the shelf at our Sta. Rosa, Laguna yard, and the bottle carries the same figure at every branch in the network. Call ahead if you need several, since stock moves.

We seal counters at installation, so this is the bottle to pick up when the water test says it is due again. We deliver across Southern Luzon and into Batangas, and the branch is open Monday to Saturday, 8 AM to 5 PM.
