Cleaners
Cleaner 304 is an especially designed liquid acid cleaner based on phosphoric and nitric acids. It finds use in a number of cleaning applications where strong mineral acids are required to solubilise metal salts on concrete surfaces.
Cleaner 304 does not contain hydrochloric or sulphuric acids, which may contribute to efflorescence.
APPLICATIONS
Cleaner 304 is especially suited to the removal of efflorescence from concrete, clay and terracotta surfaces. Cleaner 304 will also remove dirt and attack vegetable oil and fat spots on these surfaces.
It is important to note that the paved area to be treated must be dampened with water before applying Cleaner 304. Always check in an inconspicuous area to ensure that no discolouration or patchiness occurs following application. Uniform application of Cleaner 304 is essential. In all cases it is recommended that a small area of the surface to be treated is tested before full-scale treatment.
On concrete pavers, Cleaner 304 should be applied as a diluted solution from between one part of Cleaner 304 to 15 parts of water. Dilution rate will depend on the difficulty encountered in removing spoils etc. Concentrated Cleaner 304 is corrosive and will cause pitting of concrete; however it is gentler on the surface of a concrete paver unlike hydrochloric acid. Contact time should be limited to no more than 3 minutes.
Apply Cleaner 304 in a diluted format (see data) from a bucket and broom or brush into the surface for approximately 20 seconds concentrating on the areas most affected. Once applied leave Cleaner 304 on the surface of the paver for between 30-60 seconds.
The amount of time you leave the product on the surface will be based on the level of efflorescence experienced. Obviously a higher level of efflorescence will require a stronger concentrate of Cleaner 304 and a longer application rate and VICE VERSA.
After this period has elapsed the pavers must be rinsed with a high pressure hose, or garden hose at a very high volume. A high pressure hose is more effective in removing Cleaner 304 from the paver surface and neutralising the area and is recommended.
Continue to follow this process in cleaning the entire paving area working from the highest point and working towards the lower point in your paving area. Remember to work with a dilution ratio and application timeframe that works best for your paving project.
Clay and Terracotta surfaces are more resistant to the effects of acid and longer contact times and stronger solutions may be used. The surfaces should be rinsed and neutralised after application.
Please Note: It is highly recommended that you clean your pavers once laid with CLEANER 304 prior to the application of an appropriate sealer. Miteq can advise of various sealers that would be most suitable providing long lasting protection for your paving area.
