Sealing Pipe Gaps Made Easy
MR. JO Tecbond – IW
Trusted by plumbers. Chosen by professionals.
The Challenge:
Every time a core is drilled in concrete to run plumbing pipes, a gap remains between the pipe and the concrete wall or floor.
This gap must be sealed permanently to prevent:
- Water seepage
- Pest entry
- Loss of insulation or fire protection
- Unpleasant smells or air leakage
🧱 Traditional sealants or cement grouts often crack, shrink, or fall off over time. Silicone-based materials lack strength and can detach when pipes move slightly. And dense mortars don’t bond well to PVC or metal.
✅ The MR. JO Tecbond-IW Advantage:
MR. JO Tecbond – IW is a low-viscosity, epoxy-based sealing system designed to:
✔️ Flow around pipes effortlessly
✔️ Form a strong bond to concrete, PVC, metal, or HDPE
✔️ Cure into a solid, sandable mass
✔️ Withstand dampness, water pressure, and moderate pipe movement
How It Works:
- Prep the area – Clean the gap and surface with a brush and remove any oil, dust, or moisture. Use IPA or acetone to degrease.
- Mix the adhesive in 100:80 ratio (Part A:Part B). Stir well till uniform.
- Pour the material slowly around the pipe. Its self-leveling flow will naturally fill the void.
- Let it set – Within 6–8 hours it forms a tack-free surface. In 24 hours, it’s ready to be overcoated, tiled, or finished.
🧰 Why IW Wins:
- Superior bond to all construction materials
- Zero shrinkage unlike cement grouts
- Resistant to water, solvent, and mild chemicals
- Flowable – no sag or lumps during application
- Color options – grey-white or beige to match common building materials
🧠 Pro Tip:
- Add stone dust or silica flour if a thicker consistency is needed.
- In vertical applications, create a small formwork with tape or a clay dam before pouring.
🧩 Where It’s Used:
- Apartment plumbing core sealing
- Drain pipe riser sleeves
- Fire line or HVAC duct entries
- Electrical conduit protection
Strong. Seamless. Lasting.
That’s what MR. JO Tecbond-IW delivers — a plumber’s best-kept secret.
