As the nights slowly draw out, now’s the perfect time to seize a fine day and get your paths and patio ready for spring. From small terrace to lavish, landscaped setting, all will benefit greatly from a tidy and deep clean – and using professional treatments will make a real difference in terms of ongoing maintenance.
End of winter clean
To properly remove stains and ingrained dirt, we recommend a thorough wash with LTP Grimex. A blast with a jet wash may seem like a quick and easy way to clean pavers but it will only wash dirt off the surface. Use of excessive amounts of water can exacerbate staining and slip issues and jet washing can also loosen grout, erode a stone surface and damage any protective sealant applied. A specialist treatment will react with ingrained residue and organic matter, drawing it out of the stone’s porosity, and will also help to prevent regrowth of algae and other organic material.
Before cleaning, remove furniture, pots and other objects, and sweep the pavers to remove all leaves and residue. Then, test your cleaning solution on an inconspicuous area.
How to apply LTP Grimex:
- To remove mild staining, dilute one part of Grimex with 10 parts of warm water. Wash the surface thoroughly, using a brush or yard broom, and rinse with clean water.
- For more severe staining, dilute one part of Grimex with 3 parts of warm water. Agitate with a scrubbing brush and leave to act for 5-10 minutes, adding more solution to keep the surface wet.
- Sweep up any residue and rinse thoroughly with clean water.
If your pavers are stained with slippery black spot, lichen, moss and algae, they will benefit from a targeted treatment with LTP Blackspot & Algae Remover. Designed to break down microspores and black spot ‘hyphae’ before they colonise, LTP Blackspot & Algae Remover is acid-free, so it’s safe to use on acid-sensitive stone. However, it does contain a bleaching action to remove stains, so test first on an inconspicuous area.
How to apply LTP Blackspot & Algae Remover:
- Remove furniture and other items from the area to be treated.
- Apply neat Blackspot onto clean pavers with a plastic watering can or light pressure garden spray.
- Leave to absorb for 2-4 hours; the product will begin to fizz as it gets to work.
- Hose off thoroughly with clean water.
Stopping water ingress
Once you’ve cleaned your pavers and they’re dry, it’s an ideal time to replace any lost jointing sand or cement mortar. This will stop the ingress of water and will help protect paving during next winter's freeze and thaw cycle.
Added protection
If your pavers haven't been sealed, consider applying a protective treatment. We recommend LTP External Stone Sealer for natural stone and our barrier treatment, LTP Porcelain Tile Protector for matt porcelain pavers. Both are non-film forming and will help prevent the absorption of moisture and organic particles, reducing staining and the spread of algae, mould and black spot.
LTP External Stone Sealer is a water-based, impregnating sealer that’s applied using a foam roller or paint brush. It can be applied over residual moisture and will protect pavers from moisture, stains, weathering and efflorescence. It’s also UV resistant and non-yellowing.
LTP Porcelain Tile Protector creates a barrier against organic matter and makes ongoing maintenance easier. On newly laid tiles, it also protects against staining and helps increase working times. Our External Porcelain Tile guide includes lots of useful information on cleaning, protecting and caring for these surfaces.
