How it works

From the problem to the result

Scroll through four common jobs: the problem, the fix and the result.

CHRYSO Flexseal 180

Two-component flexible waterproof coating for roof slabs, terraces, bathrooms, walls, pools, tanks…

Used: CHRYSO Flexseal 180, CHRYSO Tapelastic Premia, CHRYSO Proof Acrylic

Seepage: 100% → 0 Illustrative

Roofs and terraces

වහලය සහ ටෙරස්

A cracked terrace that lets the monsoon rain through

  1. The problem Heavy monsoon rain finds its way through hairline cracks in the slab, and the leak shows up in the rooms below.
  2. The fix A flexible, seamless coating is rolled across the surface and bridges the hairline cracks.
  3. The result Water beads up and runs off the surface instead of soaking in.

Waterproof coatings do not repair structural cracks. Flexseal 180 and Tapelastic Premia are two-component systems: follow the manufacturer mixing instructions.

CHRYSO Aquaseal

Mixed into concrete and mortar to reduce water absorption and penetration. Helps…

Used: CHRYSO Aquaseal, CHRYSO Armourcrete

තෙත බිත්ති

Damp rising up the wall

  1. The problem Ground moisture wicks up the wall, leaving dark patches and white salt on the surface.
  2. The fix A waterproofing compound is mixed into the new plaster and applied over the damp wall.
  3. The result The wall is clean and dry, ready for paint or tiles.

Tile fixing and joints

ටයිල්

Loose tiles and cracked grout

  1. The problem Tiles lift and sound hollow, and the grout cracks, letting water under the floor.
  2. The fix Excem TA 30 tile adhesive is combed onto the bed, and each tile is pressed into place.
  3. The result The tiles sit firm and flush, and Excem TG Plus fills the joints for a neat finish.

Tile grout alone does not waterproof a bathroom. Waterproof first.

Concrete, bonding and repairs

කොන්ක්‍රීට් අලුත්වැඩියා

A crumbling patch on weak concrete

  1. The problem An old patch breaks away from the slab, and weak concrete wears out faster.
  2. The fix Bond GP is brushed onto the old surface, then repair mortar goes in while the bond is still tacky. Premia SL 353 in the mix adds strength.
  3. The result The new repair bonds to the old concrete, and the surface is solid again.
