The “Sand” in Sandstone

Sandstone is a sedimentary rock, formed from debris deposited of silica granules by wind or water, and consolidated with amorphous silica or calcium carbonate cementing matrix, often in conjunction with aluminum or iron oxide, which contributes yellow, orange or brown coloration.

Sandstone is very porous and one of the softest types of stone. Water and oil absorb into sandstone within seconds and, over a longer period, water and especially water borne salt can do severe damage to the surface. All sandstone must be sealed to help keep it intact, free of salt efflorescence and looking good.

To maintain the look, breathe-ability and slip resistance of the sandstone, it is important to use a high quality, invisible impregnating sealer. Topical sealers will trap moisture in the stone, which can damage it in time.

Total Seal’s impregnating sealers are safe and suitable to seal sandstone surfaces of all types – from wall cladding to floors, outdoors and in, residential and high traffic commercial.
