Long-Lasting Water Repellent for Brick, Stone & Masonry
Sovereign Weather-Chek Façade Cream is a high-performance, one-coat treatment formulated to protect porous masonry surfaces from water ingress, damp penetration, and freeze-thaw damage. Its silane/siloxane-based cream formula penetrates deeply and cures to form a breathable, clear barrier — all without altering the appearance of the surface.
Ideal for brick, stone, concrete, render and mortar joints, Weather-Chek improves thermal efficiency, reduces heat loss, and guards against the damaging effects of moisture — including algae, mould, and salt bloom.

One-coat paste formula – no drips or overspray, reduces labour and mess

All of our C16 and C24 graded timber is regularised
Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
The variation you require will determine the exact lead time and delivery method.
