The solution should be applied to saturation without pressure and in several (2-4) coats. Remove excess product and do not allow to pool on the surface.

Test Patch

It is essential that you test on terracotta and bluestone pavers before using, to ensure that the original colour and appearance is unchanged.

The reaction of Aquastop Silicon Sealer on different brands and batches of pavers will vary greatly and individual jobs should be thoroughly tested before sealing whole surfaces.

A number of pavers on every specific job should be individually tested to satisfy the client that the sealed appearance of the pavers is satisfactory.
