Trusted by South African Homeowners
From SA tenants who got their deposits back.
"My landlord wanted R3,500 for 'mould damage'. I sealed the bathroom in 20 mins, sent photos before/after. Got my full deposit back."
"Was quoted R4,200 to redo silicone. Bought 4 rolls for under R600. Did it myself in 40 mins. Looks better than the original."
"Tried bleach, scrubbing, vinegar — mould kept coming back every week. Applied KYNDO once. 3 months later, still spotless."
"Sceptical at first — looked too easy. Sealed entire bathroom in 20 mins. No drying time, no mess. Wish I'd found this 2 years ago."
You're not the problem. Your bathroom is.
You scrub. You bleach. By Wednesday — the black mould is back.
It's not dirt. It's the silicone, cracked from inside. No cleaning fixes a broken seal.
Compare with the alternatives:
Why KYNDO works when silicone always fails.
- Industrial butyl adhesive — bonds permanently to ceramic, glass and tile. Same compound used in commercial waterproofing.
- Pre-formed seal — no liquid, no drying, no cracks. One continuous waterproof barrier.
- UV + mould resistant — won't yellow, peel or grow mould like silicone does within 12 months.

FAQ - KYNDO SealStrip Pro
Will this hold up to hot showers?
Will this hold up to hot showers?
Yes. Industrial butyl adhesive — rated up to 80°C. Hot water and steam don't loosen it.
Most SA bathrooms hit 40-60°C max. KYNDO is built for harder use than that.
My silicone is already mouldy. Do I need to remove it first?
My silicone is already mouldy. Do I need to remove it first?
Nope. Just clean the surface dry and apply KYNDO directly over the old silicone.
The new seal blocks the mould from breathing. No more black corners — even on top of bad silicone.
Will this actually stay sealed long-term?
Will this actually stay sealed long-term?
KYNDO is built to last 5+ years on properly cleaned surfaces.
If it lifts, peels or fails within 365 days, you get a full refund. No questions asked.
Will my landlord accept this as a permanent fix?
Will my landlord accept this as a permanent fix?
Yes — and here's why it matters.
KYNDO leaves no damage when removed. You can apply it, document with before/after photos, and protect your deposit. Most SA landlords prefer a clean white seal over visible mould any day.
Is this just expensive duct tape?
Is this just expensive duct tape?
No. Duct tape uses rubber adhesive that fails on humidity within weeks.
KYNDO uses industrial butyl — the same compound used in commercial waterproofing on building roofs. Different product. Different result.
What if I mess up the application?
What if I mess up the application?
Lift it gently and reapply. The adhesive holds even after one re-position.
