SEK Surebond SB-1300 is the sealer SEK built the rest of its line around. It is a water based acrylic copolymer that stabilizes the joint sand and seals the paver surface in a single application, and it dries clear to a matte, natural look finish. The point of SB-1300 is protection and joint stability, not a change in appearance: no gloss, no sheen, no darker paver.
It suits homeowners and contractors who want a sealed, stabilized patio, walkway or wall that still looks unsealed, especially in shaded spots where mold, moss and algae are the real problem. This guide covers what SB-1300 is, where SEK rates it, the prep and application sequence, and how much you need, using figures from the SEK Surebond product literature and our product page, with the SEK data sheet as the final word.
Quick answer
- SB-1300 is a water based, single component acrylic copolymer that stabilizes joint sand and seals the surface in one pass, drying clear to a matte finish.
- Coverage per SEK: 80 to 120 sq ft per gallon with joint stabilization, 150 to 250 sq ft per gallon for sealing only, one coat.
- Antifungal (inhibits mold, moss and algae) and breathable, so it does not trap moisture or efflorescence under a film.
- Apply to a clean, dry surface and test a small area first. SEK does not recommend it on granite, marble, asphalt or glazed and ceramic tile.
What SEK Surebond SB-1300 is
SEK Surebond SB-1300 Joint Stabilizing Paver Sealer does two jobs at once. Its headline traits, as SEK describes them:
| Trait | What it means on the job |
|---|---|
| Joint stabilizing plus surface sealing | Stabilizes joint sand and seals the surface in the same application |
| Matte, natural look | Protects the paver without announcing that anything was applied |
| Milky white when applied, dries clear | You can see your coverage while you work |
| Antifungal | Formulated to inhibit mold, moss and algae on shaded patios |
| Breathable | Does not trap moisture or efflorescence under a film |
| Stain resistant | Spills sit on the surface rather than soaking into the paver |
| Reduced sand washout | Fewer weeds, fewer ants, less joint refilling |
The breathable point matters more than it sounds. A sealer that traps moisture or efflorescence under a film is how sealers end up causing the white bloom they were meant to stop. The antifungal point matters most on shaded, damp patios, where mold, moss and algae are the usual complaint.
Not sure matte is the look you want? Our guide to wet look vs natural look paver sealer covers the choice. Finish is permanent until you strip it, so decide before you buy.

Where to use it (and where not to)
SEK rates SB-1300 for:
- Concrete and clay pavers
- Stamped and flat concrete
- Masonry and exposed aggregate
- Natural and manufactured stone
- Segmental retaining wall block and concrete walls
- Horizontal and vertical surfaces
SEK also states it can be applied immediately after installation. These are the manufacturer's exclusions:
- Granite and marble: not recommended.
- Asphalt: not recommended.
- Glazed or ceramic tile: not recommended.
Natural stone and clay vary batch to batch, so SEK asks for a test patch every time to confirm both performance and appearance.
How to use SEK Surebond SB-1300
Follow the label and the current SEK data sheet. The sequence from the product page:
- Clean the surface. Every SEK sealer wants a clean surface. Efflorescence, ground in dirt or an old failed sealer has to come off first, or the new sealer bonds to the contamination instead of the paver. See how to clean pavers before sealing and when to use efflorescence cleaner.
- Let it dry. The surface must be dry before you seal.
- Test a small area. SEK asks for this every time. Our SB-1300 8 oz sample is enough for a test patch. We fill those sample bottles ourselves; we carry the sealer itself in the 1 gallon size.
- Apply one coat. SEK's coverage figures are based on one coat. The how to video on our product page shows a thin, even coat from a pump sprayer, back rolled with a roller.
- Watch the color. SB-1300 goes on milky white and dries clear, which is how you can see your coverage while you work.
For timing before you walk or drive on the surface, follow the SEK data sheet. Our articles on how to seal pavers and how long to wait after sealing give the general picture.
How much SB-1300 you need
Coverage splits hard depending on whether you are stabilizing joints or only sealing the surface. Stabilizing pulls sealer down into the sand, so it uses far more.
| Use | Coverage per gallon, one coat | 400 sq ft patio needs |
|---|---|---|
| With joint stabilization | 80 to 120 sq ft | About 3.3 to 5 gallons |
| Sealing only | 150 to 250 sq ft | About 1.6 to 2.7 gallons |
SEK notes that porosity, age and application method move the real number, so round up. Run your own square footage through the paver sealer coverage calculator.
Safety and storage
SEK lists SB-1300 as water based, non hazardous, and VOC and EPA compliant. For protective equipment, ventilation and storage conditions, read the SEK safety data sheet in our TDS and SDS library.
Frequently asked questions
Will SB-1300 make my pavers shiny or darker?
No. SEK describes it as a natural look, matte finish. It goes on milky white and dries clear.
Does SB-1300 stabilize the joint sand?
Yes. It stabilizes the joint sand and seals the surface in the same application, and the product page lists reduced sand washout, with fewer weeds and ants, as a benefit.
How many square feet does a gallon cover?
80 to 120 sq ft per gallon when stabilizing joints, or 150 to 250 sq ft per gallon when sealing only, based on one coat.
Can I seal new pavers right away?
SEK states SB-1300 can be applied immediately after installation. The surface still needs to be clean and dry.
Can I use it on granite or marble?
No. SEK does not recommend SB-1300 on granite, marble, asphalt, or glazed or ceramic tile.
