Dura-Rubber liquid rubber coating is a fast-working, single-part sealant that’s both tough enough for professional use and easy enough for anyone to apply.  

Drying Time
Touch-Dry: 1–2 hours
Recoat Time: 4–6 hours  Feels dry, but not fully set

Curing Time
Light Use: 24–48 hours
Full Cure: 5–7 days
Fully hardened and waterproof

Quick Tip
Dry = “feels dry”
Cure = “fully done and tough”

For best results, you should wait at least 28 days before coating a new concrete slab with Dura-Rubber. This allows the concrete to fully cure and for excess moisture to evaporate.

Before applying Dura-Rubber, ensure the concrete meets these conditions:
 -Moisture Content: The slab should have a moisture level below 5% (use a moisture meter to check).
- pH Level: The pH should be between 7 and 10.
- Surface Prep: Etch or mechanically profile the concrete to create a suitable bonding     surface.
- Clean & Dry: The surface must be free from dust, oil, and contaminants.

If you’re in a humid or cold climate, curing may take longer. Always test for moisture before applying.

How long does Dura-Rubber High Build last?

With proper surface preparation and application, Dura-Rubber High Build typically lasts 10 to 15 years before needing reapplication.

Its lifespan can vary based on several factors:

• Surface preparation – Clean, dry, and properly primed surfaces help ensure maximum adhesion
       and durability.

• Application – Applying the correct number of coats at the recommended thickness is crucial.

• UV exposure – While Dura-Rubber is UV-resistant, prolonged sun exposure can affect longevity
       over time.

• Chemical exposure – Harsh chemicals or environmental conditions can reduce the coating’s lifespan.

• Wear and tear – High foot traffic or abrasion can lead to earlier maintenance needs.

To extend the life of the coating and make maintenance easier, we recommend applying a compatible  sealer or topcoat.This added layer enhances protection against wear, weather, and staining—keeping the surface in top condition for longer.

Thinning Dura-Rubber Properly:

 Use propylene glycol (not water) if thinning is necessary.
 Add no more than 5% by volume.

 Benefits:
• Improves flow and workability • Prevents cracking during cure
• Extends open time, giving you more time to work with the coating before it starts to set up
• Ideal for spray applications or hot/dry conditions

 Do not use water to thin  it can lead to cracking and poor film formation. T

 How to Use Reinforcement Fabric:

1. Surface Prep:
    • Clean and dry the area thoroughly.
    • Remove dust, grease, or loose material.

2. Prime if Needed:
    • If a primer is required for the surface, apply the primer first and allow it to dry completely before
      continuing.

3. Repair Cracks First:
    • Deep or wide cracks must be filled with latex caulk or High-Past before applying fabric.
    • Allow the repair compound to dry fully.

4. Apply Base Coat:

    • Apply a wet base coat of Dura-Rubber to the area where reinforcement is needed. 5. Embed the Fabric:
    • While the coating is still wet, press the reinforcement fabric into the base layer.
    • Smooth it out with a brush, roller, or trowel to remove wrinkles and ensure full contact.
    • The fabric should be fully saturated with Dura-Rubber underneath. 6. Top Coat:
    • Immediately apply a second coat of Dura-Rubber over the fabric.
    • Let it dry, then apply additional coats as needed.

 Pro Tips:

    • Use reinforcement fabric on 90° wall intersections, floor-to-wall transitions, and other joint areas to
      improve flexibility and prevent water intrusion.
    • Overlap fabric edges by 2”–4” on larger areas.
    • Pre-cut pieces for corners, joints, or tight spaces. • Perfect for high-stress areas like roofs, gutters,
      pools, basement walls, and more.

Rubberizeit™ Dura-Rubber is an all-purpose, liquid rubber coating made from SBR rubber—the same durable rubber used in car tires. Designed for waterproofing, sealing, and protecting a wide range of surfaces, it’s non-toxic, easy to apply, and available in multiple colors.

It can be applied to metal, wood, concrete, plastic, fiberglass, vinyl, most plastics, and more making it ideal for projects such as pools, ponds, roofs, decks, walls, ceilings, and floors. A primer may be required on certain surfaces; please refer to the specific application instructions for details.

Non-toxic, low-VOC, and completely fish-safe, Dura-Rubber is a waterproofing solution you can trust—indoors, outdoors, even in ponds and water features.

• Non-toxic formulation
• Low in VOCs
• Fish-safe
• Safe for indoor & outdoor use (when used as directed)

Color Options to Suit Any Project

Dura-Rubber is available in a wide range of colors, with black and white as standard base options. Several popular shades are listed on our website, and for custom needs, Dura-Rubber can be tinted to match your project’s exact color requirements.

We can match most colors from the Benjamin Moore Color Classics Collection.

 More Flexible than Silicone

Silicone can crack or peel over time and cant be painted.
Dura-Rubber remains flexible and strong, adapting to movement without losing its seal.

 Easier to Apply than Epoxy

Epoxies require mixing, strict timing, and careful prep.
Dura-Rubber applies like paint, with no need for complicated setup or special tools.

 Superior UV & Weather Resistance

Silicone and epoxy can degrade under sun and water.
Dura-Rubber forms a UV-stable, waterproof membrane that’s built to last in harsh conditions.

 Low Maintenance, Long Life

Once cured, Dura-Rubber resists cracking, peeling, and wear.
No frequent resealing just long-term protection.

Generally, 9 months unopened or 6 months opened but resealed tightly and stored in a cool, dark space.
