Granite is one of the hardest stones known to man. It is, however slightly porous, even when polished and sealed. There are lots of myths told about granite. But these are the facts:

Heat

Granite will expand slightly if heat is applied. Our installers allow for linear expansion where worktops abut walls. Certain granites can discolour either temporarily or permanently – if enough direct heat is applied.
Being stone, it can absorb large amounts of heat energy, and will become hot to the touch, and will cool down gently. If you place a hot cooking pot on your worktop, the surface will become very hot to the touch, and should be avoided. You should not place hot pots or utensils directly onto the surface. We recommend worktop savers, or cooking stands.

Scratches

Granite is described as scratch resistant. The process of polishing to a high quality finish means that the gloss surface may mark if it is misused. Do not chop directly onto the surface, it could mark your worktop and damage your knife!

Stone on stone scratches the surface too. If you have a granite worktops saver, make sure it has rubber feet on the bottom. If rubbed along the surface, this can scratch. The stone often overlooked for causing scratches is diamond rings.

Again, stone on stone, is the only thing that can scratch your granite worktops. Just apply some common sense and you should be fine.

Chips and Pits

Granite comprises of grains of minerals which vary in size, distribution and colour. It is occasionally noticed that small losses of grains may appear in the polished surface. This is entirely normal, and the small pits do not impair the quality or functionality of your granite worktop. Larger losses may be termed chips, and these are normally picked up prior to manufacture and rejected.

Despite the strength of granite worktops it is possible to cause small chips by dropping heavy, sharp objects onto the surface. If this happens we are normally able to fill and repair the chip with our qualified tradesmen.

Staining and Rings Marking

If a glass of fruit juice, cordial, fresh fruit, red wine, aggressive household chemicals are left on your worktop it can penetrate the seal of the granite and leave marks. We have also heard of tonic water, foods with strong colours like beetroot, curry, etc. penetrating into the stone, causing discolouration.

If you recycle, note that rinsed containers may still have residues (eg. pickles, vinegar acid, etc.) which may affect the surface.

The last one is, unloading the dishwasher. Dishwasher water is known to comprise a cocktail of aggressive agents, so we advise our customers not to stack wet crockery straight from the dishwasher onto a stone worktop.

How we can help

At Norfolk Granite Works, we ensure your work surfaces are sealed with a stain stopper at our factory. We recommend this process to be done every 6 months to a year to ensure liquids stay on the top of the stone and don’t penetrate the seal.

We can sell you a cleaning kit, with our recommended stain stopper in it. The process only takes 5 minutes, but is worth getting in the habit of doing (95% of our customers don’t have a problem!).

What to do if your worktop is damaged

If the worktops do manage to stain, or have a ring mark, there are products we have to bring the stone surface back to its stunning self. However ,it will required one of installers to come out, which does have a cost attached. Most of the time, stain removal from granite is a 100% effective.

Plain colours will normally show up marks more than a varied granite surface would effectively disguise, which is fact to bear in mind when choosing your colour. Our black range (Star Galaxy, Absolute black, Classic Black) are especially advised to treat and use their worktops according to our specification. The blacks are by far our best sellers, but do require work to keep them looking at their very best.
