Limestone is quite durable and is an extremely good choice for a fireplace! - fireplaces Perth
However, limestone is also rather soft and comparatively porous, so it does require care in the householder to prevent stains and grubby marks spoiling the outer lining - especially for new limestone fireplaces!
Several important points for first time buyers!
Your limestone fireplace ought to be chemically sealed with a decent quality sealant. The better sealants do not change the shade of the limestone to any degree, but prevent easy penetration of possible stains from stepping into the stone. Your fireplace supplier should either seal your fireplace for you personally, (probably at extra cost) or provide a tin of liquid sealant that you should paint over the surface yourself (also probably at expense). These sealants cost around �20 or more per tin, when you see one for much less, don't use it, as it may not be good enough, and may darken your limestone fireplace colour!
For those who have a limestone hearth, this should actually be sealed twice. Leave the first coat to completely dry after which add the second. Be sure you do not apply too much sealer, as this could cause a change to the surface if soaked.
You may have to repeat the complete sealing process after about six months or a year, particularly if the fireplace is for solid fuel. Next, your limestone fireplace will likely not require any further chemical sealing.
Cleaning Limestone Fireplaces
The easiest method to clean off a grubby mark from the limestone fireplace is simply to employ a clean cotton cloth dampened with very dilute washing up liquid. Do not soak the stone though!
For those who have coffee or wine etc, spill on to your limestone fireplace surface don't panic, just clean it off thoroughly having a dampened cloth and everything should be fine. - fireplaces Perth
