Block Paving Intensive Cleaner is for cleaning dirt, grime, algae and black spot lichens from all forms of block pavers. This includes both clay-based and concrete-based block pavers. Black spot lichens are very difficult to remove, they cannot be removed by pressure washing alone. This intensive block paving cleaning solution will remove black spot lichen and other organic contaminations where jet washing has failed! Apply Block Paving Intensive Cleaner diluted at a rate of 1:1 with clean water and allow the product to dwell on the surface for at least 1 hour. Extend the dwell time when removing heavy contaminations of lichen or other organic staining. Do not allow the product to dry out during the dwell time, the surface must always remain visibly wet with product. Agitate with a stiff brush to move the liquid around the surface and to prevent pooling in low areas. The key to using Floorseal Block Paving Intensive Cleaner is to pre-wet the surface and apply the product with a sufficient dwell time. Extend dwell times to remove heavy infestations of black spot lichens when required. We find it is a little more difficult to remove black spot from cement-based block pavers than it is from clay-based block pavers. We always recommend carrying out a small test patch. This is to familiarise yourself with the application process and timings required to remove the lichens from your pavers. We also recommend working in smaller manageable sections when cleaning large areas, this makes the overall process much easier. You can revisit the odd paver or two that still require more attention whilst the product is being left to dwell on a new section. Be aware jointing materials, like kiln dried sand, can absorb liquid so add more solution periodically. We strongly advise carrying out a small test patch to determine the specific dwell time required. Try not to guess! You may need to adapt the dwell time to suit local conditions. Cool damp days are certainly more suitable than hot bright sunny days.

Yes, this product can be applied to any kind of block paver.
You can also use this product on natural stone like sandstone and limestone and clay-based tiles.
We think concrete-based pavers are the hardest to clean. Clay-based block pavers are usually the easiest to clean.
It gives the product time to kill black & white spot lichen. Black spot lichens are the most difficult organic contamination to remove. Dwell time is one of the key factors when removing them.
It will help to keep the product on the surface, therefore in contact with dirt/grime and organic staining.
If it applied to a dry surface it will sink in rapidly – you will need to use much more cleaning product if you do this.
It produces a timing you can replicate over the rest of the pavers. It takes the guesswork out of the process.
A test patch will tell you this but usually at least 15 minutes to 1 hour. You can increase the dwell time for really heavy contaminations of black or white spot lichen.
The product should be diluted at a ratio of 1:1 with clean water. If you are removing really severe black spot you can apply the product neat.
Approximately 8m2 per litre (when diluted 1:1 ).
Floorseal Cement & Grout Haze Remover is an acid-based cleaning agent for the removal of cement based hazes. It will react with concrete based block pavers, so do not apply to concretes, limestone or other acid sensitive surfaces. It is safe to use on clay-based pavers, sandstone or slate. It will not remove brush in compounds.
Floorseal Sealer Residue Remover will remove the invisible slick left either side of the joint by a brush in compound. It is suitable to use as a general pre-cleaner. It will not remove obvious mistakes made by over applying brush in compounds or other resinous compounds.
You do not actually need a pressure washer to finish the process, or require one to pre-clean with.
Pre-wet the surface with a hose pipe or a watering can. You can even use the watering can to apply the product.
Just agitate the product with a stiff brush. There is no need to scrub the surface hard. The brush is just used to move the fluid about, keeping all of the surface equally wet.
If you follow this process the surface will become clean – just rinse with water to complete. It is the dwell time, in conjunction with the product, which is doing most of the work.
