Description

A two part, thick epoxy resin with a new easier to apply formula with glass reinforcement for even greater resistance to chemical attack. Cures to form a hard surface film which withstands heavy traffic.

One thick brush applied coat is generally sufficient, although two coats may be required on porous, open textured surfaces or to achieve a watertight seal over wider cracks and joints.

Vulnerable cracks and joints, such as between the wall and floor, can also be further strengthened using Watco Fibreglass Reinforcing Tape.

Watco Bund Sealer is suitable for use both indoors and outdoors and will cure at temperatures as low as 5°C.

Carries CE Mark EN1504-2 and has excellent test results for chemical resistance. It also has an A+ VOC emissions rating with a low level of VOC.

Surface Preparation


Bare blockwork, brick and concrete – ensure surfaces are clean, dry and dust free. Usually a good sweep with a stiff broom or brush is sufficient. Any grease or oil contamination should be removed using Watco Concroff. For larger areas of bare concrete, Watco Etch & Clean can be used to remove weak cement deposits.

New Concrete – as a guide, new concrete should be left for eight weeks to dry.

Painted surfaces – abrade to remove any weak or loose paint. Check remaining paint is well bonded. Very smooth, glossy paint should be lightly abraded to provide a key. Watco Bio-D can be used to remove grease and oil from painted surfaces. Watco Concroff is a very powerful degreaser for contaminated bare concrete, (do not use on a previously painted surface since it can soften paint).

Priming – is not usually required, but for open textured, or very porous high suction surfaces, such as sand and cement screed or porous bricks or blocks, a second coat may be required.

Minor cracks/joints – such as between the wall and floor, can be strengthened by using Watco Fibreglass Reinforcing Tape. Push the tape firmly into place on top of the wet Bund Sealer so that the crack or joint runs down the centre of the tape. Push the tape onto the layer of Bund Sealer using a brush loaded with more Bund Sealer. Work the tape into the corners, joint and angles, ensuring good contact with the surface at all joints. If a join is required, overlap the tape by at least 50mm and work in as above. Allow to harden and apply more Bund Sealer over the rest of the bund or area to be sealed

Large cracks/joints – will need repairing prior to applying Bund Sealer. Please contact our Technical Department on 0113 2455450 (option 2) or send a message to [email protected] for details.



Mixing


  • Remove the two inner tins from the tall outer tin
  • Stir the contents of each tin thoroughly and pour all of the contents into the outer tin, (scrape around the inside of the tins to remove any residue)
  • Mix the components together thoroughly using a spatula or similar wide bladed tool, (a piece of wooden batten is ideal) and do not thin
  • Continue mixing until an even consistency is obtained
  • Do not mix more than one pack at a time
  • If a paint stirrer fitted to an electric drill is used, also use the spatula to blend in any unmixed material from the sides and bottom of the tin

Application


Important – once the contents of the pack have been mixed, a chemical reaction takes place which creates heat, and the product should therefore be used immediately.

Best results are obtained in warm (minimum of 15°C), dry conditions with good ventilation. Apply one thick coat with a paint brush working well into the surface. Do not exceed the maximum coverage of 14m² per 4 litre pack. Do not wash or allow water to lie on the surface for at least 7 days.



Standard Compliance


  • EN 1504-2
  • BREEAM Compliant
  • Low VOC level (35g/litre)
  • ISO 16000
  • REACH Compliant



Limitations


  • Do not apply to a wet surface or areas subject to rising damp
  • Do not apply to areas subject to movement such as structural movement or around vibrating machinery
