Wonderbond is a 100% acrylic concrete sealer offering excellent depth penetration, high resistance to acids and alkalis and other harsh chemicals, exceptional U.V resistance, and superior, long lasting water repellence all in a rapid-dry single coat.

Wonderbond not only penetrates deeply into porous surfaces but the hard wearing gloss finish will continue to protect the surface for years to come.

The acrylic seal will eliminate any annoying concrete dust and the attractive glossy finish protects against stains and makes future cleaning a breeze.

Wonderbond is perfect for high traffic areas subject to lots of wear and tear such as workshops.

The waterproof seal also helps prevent the growth of mould or mildew.

Wondercoat just gives you so many options. Wonderbond’s durability and adhesion make it a good choice as a base coat for top coating with epoxy sealers or conventional paints.

But Wonderbond also works beautifully as a top coat on its own.

Wonderbond High Quality Sealer primer and undercoat

As with any concrete sealer, preparation is the key.

Wonderbond is a straightforward one step application but you must make sure that the surface is free from dust, dirt, mould, oil or any flaking material first.

Wondercoat should not be used on surfaces with pre-existing sealers or on swimming pool surrounds.

Allow the surface to dry completely. You can apply Wondercoat with:

  • Brush
  • Short nap roller
  • Knapsack spray
  • Airless spray
  • Nylon broom
  • Lambs wool applicator.

Thinning is not recommended and coverage will range from 10 to 30m2 per litre depending on absorption rates. Apply using even strokes to ensure consistent coverage, also self levelling.

Wondercoat will be touch dry in 20 minutes and you should be able to re-coat within 4 hours.

The surface will be safe to walk on after about 2 hours and Wondercoat will tolerate heavy traffic after 24 hours.

Wash all equipment in warm water and detergent after use. A single coat will have a low sheen finish but increasing the number of coats will give a glossier finish.

Choose Wonderbond for your next concrete floor sealing project—it’s surely the most cost-effective and versatile product you’ve ever seen.

Wonderbond sealer protects against grafittiCan Wonderbond® be used as a protector against graffiti?

Graffiti can permanently penetrate a surface! When graffiti is removed, it often leaves permanent marks, which become problematic.

Wonderbond® acts as a barrier and is an ideal anti-graffiti coating where persistent offences occur.

Graffiti vandalism can be removed much more easily, and in some cases with just soap and water (the sooner graffiti is cleaned off, the better the results will be).
