Transparent waterproofing over tiles with Teknobond 660

Reliable protection of terraces, balconies, swimming pools and any concrete, stone, ceramic or even wooden surfaces without dismantling the tiles is possible with the transparent UV-resistant waterproofing Teknobond 660.

Terraces and balconies are usually tiled, but over time, microcracks appear in the seams, joints and junctions, through which water seeps under the tiles or other decorative covering. This leads to leaks, damage to the screed and, as a result, expensive repairs.

But there is a modern solution - transparent polyurethane waterproofing Teknobond 660 , which allows you to restore the tightness of the terrace without removing the tiles, while maintaining its appearance. Additionally, for sealing joints and joints, we recommend using Teknopoliderz 1K sealant in black, white, or gray. 

 

In what cases is Teknobond 660 transparent waterproofing used?

  • When leaks and microcracks appear in the seams.
  • To preserve the aesthetic appearance of tiles, waterproof and preserve natural stone. 
  • If you want to avoid expensive dismantling.
  • For quick DIY waterproofing over the coating.
  • For waterproofing terraces, balconies, swimming pools, glass brick walls
  • For waterproofing and protecting wood and metal surfaces
  • Waterproofing of metal surfaces.
  • Use on surfaces that require resistance to ultraviolet radiation.

Important: Transparent waterproofing is used when the tiles are in satisfactory condition. If there is significant delamination or damage, it is necessary to repair or replace such areas.

Advantages of transparent waterproofing Teknobond 660

  1. A transparent coating that does not change the appearance of tiles, wood, or stone, but provides reliable protection against water, moisture, mechanical and chemical influences.
  2. It can be easily applied by yourself with a roller or brush without the involvement of craftsmen.
  3. Seals seams and microcracks.
  4. Resistant to UV, water and frost.
  5. Quick recovery in case of damage. 

Transparent waterproofing without dismantling: what materials to choose for sealing tiles, stone or other coverings? 

  1. Teknobond 660 is a transparent UV-resistant polyurethane-based waterproofing.
  2. Teknopoliderz 1K is a polyurethane sealant for sealing seams and joints.
  3. Waterproofing tools:
  • Medium-pile roller, maklovitsa brush, fine-pile brush for finishing seams.
  • Low-speed mixer.
  • Sealant gun.
  • Rubber spatula.
  • Personal protective equipment (gloves).
  • A tub or bucket for rollers and brushes.

Step-by-step instructions for applying Teknobond 660 transparent waterproofing to tiles 

  1. Surface preparation
  • Clean the tiles from dust, dirt and grease. Damaged areas must be replaced or repaired.
  • If necessary, remove damaged grout between the joints.
  • Make sure the surface is dry.

 

  1. Sealing seams, joints and junctions

Use Teknopoliderz 1K polyurethane elastic sealant to fill seams, cracks and joints.

Teknopoliderz 1K is a one-component, polyurethane, moisture-resistant sealant with high elasticity, designed for sealing both horizontal and vertical joints. The material has high adhesion to concrete, stone, wood, metal and other materials. Teknopoliderz 1K sealant is resistant to moisture and ultraviolet radiation, therefore it is ideal for both indoor and outdoor use. It is resistant to chemical influences and temperature fluctuations, does not require a primer and can be painted. 

Sealant application instructions

  • Before applying the sealant, completely clean the surface from dust, grease, rust, detergents and moisture.
  • The seams should be thoroughly cleaned with a wire brush or sandblasted. Remove dust with compressed air.
  • To avoid contaminating surrounding areas, use masking tape.
  • Place the tube of sealant into the gun, cut off the edge of the package and adjust the nozzle to the width of the seam.
  • Carefully apply the sealant into the seam, pressing the trigger evenly.
  • After the sealant dries, remove the masking tape and you can proceed to applying the Teknobond 660 transparent waterproofing.
  1. Priming

The special feature of Teknobond 660 transparent waterproofing is that you do not need to prime the surface or dismantle the tiles. Transparent waterproofing is applied directly to concrete, stone, brick, tile, metal, forming a completely transparent membrane, reliably sealing microcracks in the surface without changing the appearance, texture and color of the finishing finish. 

  1. Applying transparent waterproofing Teknobond 660
  • Add component B to component A and mix thoroughly for 2-3 minutes until smooth using a low-speed mixer (up to 400 rpm).
  • Apply the first coat with a brush or roller evenly over the entire surface.
  • Let it dry (after three days the surface is ready for pedestrian loads, the material is completely dry after 7 days).
  • If necessary, apply a second coat to create a strong waterproofing film.

Useful tips before applying transparent waterproofing

  • Perform work in dry weather and at surface temperatures between +5°C and +35°C.
  • Avoid getting debris on the surface while the clear waterproofing is drying.
  • Do not use the coating for intensive point loads or moving heavy furniture. 
  • To repair minor damage, it is sufficient to apply Teknobond 660 locally.

You can see that the transparent waterproofing Teknobond 660 in combination with the polyurethane sealant Teknopoliderz 1K is a simple but extremely effective solution for restoring the tightness of a terrace or balcony without the need to dismantle tiles or other finishing coatings. This approach allows you to quickly and at minimal cost eliminate leaks , protect structures from moisture and prevent further destruction of the cladding or base.

The system works comprehensively:

  • Teknopoliderz 1K seals tile and expansion joints, remaining elastic even during temperature fluctuations,
     

  • And Teknobond 660 forms a transparent, ultraviolet-resistant film on the surface, which preserves the decorative appearance of the coating and provides long-term protection against moisture, precipitation and dirt.
     

This method is ideal for local repairs or preventive waterproofing on exposed surfaces – both in private and commercial properties.

By following the recommendations for surface preparation and application of materials, you can independently carry out waterproofing work without resorting to expensive services of craftsmen and without unnecessary construction dirt. This allows not only to save money, but also to extend the service life of the entire structure, preserving its aesthetics and functionality for many years.
