LTP has launched an external sealer – Paving, Patio & Masonry Sealer – to its range of protection treatments. The water-based solution can be used on all types of stone surfaces, where it strongly repels water, oil and grease. It also helps reduce efflorescence and delicately enhances natural tone whilst allowing surfaces to breathe.
LTP Paving, Patio & Masonry Sealer can be used on honed, rough cut, flamed and brushed stone surfaces, including limestone, granite, cement, slate, bricks and blocks. As well as protecting surfaces from organic dirt, and promoting easier maintenance, it also protects against moisture ingress, helping to prevent green growth on paths, patios and walls.
The new treatment is said to be quick drying and easy to apply. Before application, surfaces should be clean, dry and free from dirt, grime, cement and grout residue.
To prepare a newly installed patio, first clean with a dilute 1:5 solution of LTP Grimex. To remove cement-based grout residues, use LTP Cement, Grout & Salt Residue Remover and to remove resin residues left on the surface after applying a brush-in grout, use LTP Solvex. To prepare existing and older surfaces that are covered in detritus, algae and lichen, etc., use LTP Blackspot & Algae Remover.
Once pavers are dry – after 24 hours – LTP Paving, Patio & Masonry Sealer is applied with a roller, paint brush or light pressure sprayer. Further coats can be applied at hourly intervals on more porous materials until the surface is fully saturated; this is normally achieved when a reasonably even layer of sealer is still visible 20 minutes after application.
Surfaces can be walked on with light traffic after the sealer has fully absorbed and returned to full service after 24 hours. Children and pets should be kept away from treated areas until the sealer has fully absorbed and dried.
