Vacuum shot blasting and sealing:
This involves shot blasting the existing markings to remove the paint and take the surface back to the original concrete, the surface is then sealed using a clear sealant to ensure there are no future issues with dust being created etc.
For this method, we apply a solution similar to a paint stripper to the markings, this is then left for a few minutes before being scraped away to remove the existing paint. The area is then cleaned with a solvent to remove any residue.
This method of removal uses a sophisticated water pump system which generates up to 40,000psi to completely remove existing markings. Excess water and waste is then drawn by vacuum into a separate collection tank. This unique system is able to remove lines or other surface debris without marking the surface below
This method is the same as the shot blast removal option, however instead of sealing the floor with a clear sealant, we apply a grey paint which is matched as closely as possible to the colour of the slab. This helps the area where the markings have been removed to blend back in with the rest of the floor.
For the removal of external markings, a HCA lance (hot compressed air) uses a mixture of propane gas and compressed air which can be used to remove existing markings and also for drying external surfaces prior to the application of new markings.
