Seal Granite and Travertine in New Builds Before Day One

Granite and travertine are easy to sell. They look like money in a listing photo, and buyers ask for them by name.

They are also natural stone, and natural stone is porous. A countertop that looks flawless on closing day is still a surface that can absorb liquids, pick up stains, and show wear from the first week of cooking.

That is why sealing belongs on the new-construction checklist, ahead of Day One.

Why natural stone needs protection

Natural stone has tiny openings that take in what touches it. Coffee, oil, wine, and water can all be drawn in, and once something has soaked into stone it is far harder to deal with than something that sat on the surface.

Granite and travertine are different from each other, and the details matter. Travertine in particular has a naturally pitted, open character, so it tends to be more absorbent than a tight-grained slab. Whatever the stone, the principle is the same: protect it before it is used.

Diamond Bond Oregon has been sealing, protecting, and restoring glass and stone surfaces for over 25 years. Our sealant creates an invisible barrier that repels water and resists stains. It also protects against absorption, which is the real problem with porous stone.

For specifics, see the pages on granite and travertine and marble and natural stone.

Why before Day One, not after

You can seal stone at any point in its life. The advantage of doing it in new construction is that you start from a clean slate.

• Nothing has soaked in yet. An unused countertop has no stains, rings, or oil marks to deal with before sealing.
• The house is empty. There is no cookware on the counter, no furniture in the way, and no one working around a family.
• It fits in one visit. After the final clean and before the walkthrough or move-in, Diamond Bond coordinates with the builder's schedule and handles the stone.
• The buyer gets the benefit from day one. The first spill of red wine at the housewarming meets a sealed surface, not a bare one.

Waiting until after move-in turns a simple protective step into a cleanup-and-restore job, and it often comes with a call to you first.

Where the stone shows up in a new build

It is not only the kitchen. Think through the whole house:

• Kitchen counters and islands
• Bathroom vanity tops
• Travertine tile in showers, floors, and tub surrounds
• Fireplace surrounds and hearths
• Entry and flooring stone

Every one of those surfaces sees water, cleaning products, or food. A builder in Tigard or West Linn working on a spec house with a travertine primary bath is looking at a lot of square footage that has never been protected.

Talking to buyers about it

Buyers appreciate a builder who thinks about how the house will hold up. A sentence in the walkthrough, such as "the stone was sealed before closing," tells them you cared about the details.

Pair it with care guidance. Diamond Bond's cleaning instructions explain how to maintain sealed surfaces, and the Diamond Bond Cleaner & Revitalizer is the retail product for it. A sealed surface still needs the right cleaner and prompt attention to spills.

What to look at before you schedule

Every job is different, so a quick walk-through helps. Before sealing is scheduled, it is worth having a short list ready:

• Which stone is in which room, and how much of it there is.
• Whether the stone is polished, honed, or textured. Tell us what you know and we can take it from there.
• Where the stone sees the most water or food: kitchen counters, vanities, shower floors.
• When the final clean and walkthrough dates are set, so sealing lands between them.

If you are not sure, ask. Diamond Bond will look at the job and tell you what makes sense. A free estimate costs nothing and carries no obligation.

The cost of waiting

Most stone problems are quiet at first. A faint ring under a bottle of olive oil. A darker patch near the sink. A travertine shower floor that holds water a little longer than it should. None of these is dramatic on its own, but each is the start of a conversation between the owner and you.

Sealing before the first use takes that conversation off the table. It is also the lower-effort moment: no stains to treat first, no household to work around. Waiting means a harder job for the same surface.

A word on marble

Marble is a natural stone too, but it is its own conversation, especially in luxury homes. We cover it in Marble in Luxury Homes: Protect It Before the First Spill.

Frequently Asked Questions

Is granite already sealed when it's installed? Some fabricators apply a treatment, and some do not. Diamond Bond can look at the job and tell you what makes sense. Call 503-998-4007 or request an estimate and we will walk through it with you.

Does travertine need different handling than granite? Each stone has its own character, and travertine is generally more absorbent. Describe the stone and the location when you call, and Diamond Bond can recommend how to approach it.

When should sealing be scheduled? After the final clean and before the walkthrough or move-in. Diamond Bond coordinates with your schedule so it fits with your other trades.
