Frequently Asked Questions
-
Klean-Bloc™ is Techo-Bloc’s built-in surface protection technology designed to help your pavers, slabs, and walls stay cleaner and look better for longer. Applied during manufacturing, Klean-Bloc forms a bonded protective layer on the surface that repels water, oils, and dirt, preventing stains from penetrating. This not only reduces maintenance but also enhances color vibrancy with a subtle gloss finish. Unlike traditional topical sealers, Klean-Bloc doesn’t peel or wear unevenly — it’s baked in to last.
-
You can identify Klean-Bloc™ products in two ways:
- Visually – they feature a noticeable gloss or sheen that sets them apart from untreated surfaces.
- Officially – look for the Klean-Bloc icon in the product spec book, on product tags, and on the product’s web page under technical details.
-
Klean-Bloc is applied to select slabs, pavers, and some vertical products. These are clearly marked with the Klean-Bloc icon on product tags and spec pages.
-
It adds a subtle gloss finish that enriches color without affecting texture or slip resistance. The gloss does not make the surface slippery and enhances visual depth and richness.
-
There may be a slight price premium, but Klean-Bloc provides great value by eliminating the need for sealing and reducing maintenance and cleaning costs.
-
Yes. Since it is built into the product and does not wash away, Klean-Bloc reduces the need for chemical cleaners or repeated sealing. It’s a more sustainable way to keep your hardscape looking great.
-
If your Klean-Bloc surface gets chipped, a Klean-Bloc touch-up kit is available to help repair and reseal the affected area. This allows you to camouflage chips and other minor damage.
-
Yes. Klean-Bloc products are engineered to withstand de-icing salts used in winter climates. However, we always recommend using salt alternatives that are gentle on landscaping and hardscapes when possible.
-
You can perform a simple absorption test: Sprinkle water on the surface — if the surface quickly darkens, absorbs and forms a dark circle, it’s time to reseal. If the water beads up, the protection is still active.
-
No additional sealing is required at installation. Klean-Bloc is factory-integrated and does not require initial treatment. Re-sealing is optional only after years of wear, if you want to restore its original level of protection and gloss.
-
Yes — but it’s usually unnecessary. Most spills and dirt can be cleaned with soap and water. If using a pressure washer, use low pressure and a fan tip to avoid disturbing joint sand.
-
Klean-Bloc repels:
- Oils and grease (cars, grills, tools)
- Food and beverages (wine, sauces, coffee)
- Dirt, leaves, and other organic matter
- Some efflorescence when paired with proper base materials
-
Yes. Because it repels moisture, it reduces the amount of water that can enter the product and freeze. This helps prevent surface cracking and long-term wear in freeze-thaw climates.
