Duraline 801

Works from inside the concrete to block water and prevent leaks for lasting and reliable protection

Product Details

Protect your concrete retaining walls and pools from dampness with this "breathable" shield. It penetrates deep into the surface to form "crystals" that block pores and minor cracks, stopping water from seeping through even under pressure, while keeping your drinking water safe and non-toxic.

Slabs, Walls, Tanks & Damp Areas

25 kg paper bag

  1. Prep the Surface: Scrub the area clean of dirt, grease, and loose paint. If you have active leaks (running water), plug them first with a specialized product like Duraplug 208. Smooth out corners with a small cement "slope" (fillet).
  2. Wet the Area: Lightly spray the surface with water so it is damp.
  3. Mix: Slowly add the Duraline 801 powder into clean water (use about 7–8.5 liters of water per 25kg bag). Stir for 3 minutes until it’s a smooth, lump-free paste. Use it within 30 minutes.
  4. First Coat: Use a stiff brush to scrub the mixture into the surface, making sure to fill every tiny hole and gap.
  5. Second Coat: Once the first coat is dry enough to touch but still slightly damp, apply the second coat. Brush it on at a 90-degree angle (cross-wise) to the first coat for a perfect seal.
  6. The "Wait" Period: Mist the surface with water for 5 days to help it cure properly. Keep the area away from rain, sun, or frost for at least 24 hours.
    If you are filling a tank or backfilling soil, wait at least 14 days (or 7 days if the surface is very hard).
  7. Clean Up: Wash your tools with water immediately.

💡 Quick Tips: If the mix starts to thicken in the bucket while you're working, just give it a quick stir. Never add more water!
