Bring your block paving back to life with our outdoor cleaner for block pavers

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.
