Welcome to the future of Blast Cleaning
Until now pressure washing was the only effective way to remove the waxy residue left over on concrete surfaces that had been protected with Sika Ferrogard 903. It is essential to remove this residue in order to achieve a bond between the concrete substrate and subsequent anti-carbonation coatings, but pressure washing requires around 15 litres of water per minute to be effective. Over the course of several days this amounts to a lot of water, all of which is a potential threat to the wooden flooring. Concrete Renovations Ltd remedied the problem with the revolutionary Sponge Blasting method.
