Dupont Premium Laticrete StoneTech Professional Heavy Duty Sealer

Natural stone is an elegant addition to any home.

No matter where you use natural stone, it elevates the mood and feel of any room or space. But while we think that stone is hard, it’s actually porous and can easily absorb spills or stains. That’s why using natural stone in areas such as your kitchen can damage your natural stone investments. 

Dupont Premium Laticrete StoneTech Professional Heavy Duty Sealer


Etch marks are perhaps one of the most common damages that occur on natural stone. These tend to occur the most on limestone, travertine, and marble that hasn’t been properly sealed. 

If it’s your first time working with natural stone in your home, don’t think that you can easily remove etch marks through spot cleaning. They are extremely difficult to remove, which is why sealing is essential. 

Sealing your natural stone is the only efficient way to buy time in order to wipe up spills. It also gives the added advantage of slowing down the reaction time between alkaline or acid substances and the stone’s calcium carbonate content. 

Fortunately, there’s Laticrete StoneTech Professional Heavy Duty Sealer. This sealer was made specifically for natural stone; its advanced penetrating microbond protecting formula leaves you with heavy-duty protection from most kinds of spills and stains.

Though this sealer sure makes cleaning a lot easier, what it really does is saves you money by making sure your natural stone investments are always protected.

Dupont’s Laticrete Stonetech line is a household name in natural stone sealers. This water-based formula offers professional-grade protection for natural stone, so you don’t have to shell out hundreds of dollars just to get your stone investments professionally sealed.

If you’re worried that this product will alter the look of your stone, it doesn’t. In fact, the natural beauty of your stone will be enhanced even more after sealing, because it protects so well especially from etches, spills, and stains.

Anyone who’s ever used natural stone on their countertops, backsplashes, walls, and floors can tell you that it’s a headache to clean and maintain without proper sealing. And that’s precisely what Laticrete StoneTech Professional Heavy Duty Sealer does – aside, of course, from making your life much easier. 

Use this sealer on a variety of surfaces. It works well on granite, slate, travertine, marble, sandstone, flagstone, Saltillo tile, limestone, and even grout. This sealer can also be used on stones both inside and outside your home.

How To Use

Applying Dupont Premium Stone Sealer like a pro is almost too easy!

Keep in mind that it’s important to follow the directions on the label for the best results. Before you start, test on a small area then let it cure for 24 hours. If you are working on newly installed grout, let it cure for at least 72 hours before application.

The surface must always be free from coatings, waxes, and dirt. It works best when surface temperatures are between 50F and 80F.

  1. 1
    Make sure that the bottle cap is closed, and give it a thorough shake.
  2. 2
    Mask off any areas nearby that will not be treated.
  3. 3
    Apply an even coat liberally using a brush, roller, paint pad, or low-pressure sprayer.
  4. 4
    Let the sealer penetrate the surface for 15 minutes, during which the surface should be kept wet with the sealer. If it dries up, just add more as needed. Never allow the sealer to dry on the surface.
  5. 5
    Using clean towels, wipe the surface area dry.
  6. 6
    If you are working with extremely porous surfaces, apply a second coat if needed. This should be done within 40 minutes of the first application.
  7. 7
    If you find any sealer residue, wet the area again with sealer then agitate it with a white nylon scrubbing pad and wipe dry with a clean towel.
  8. 8
    Full curing should be completed within 24 to 72 hours. The surface may be used after 8 hours.

It’s that easy!
