Here is a Limestone table that we stripped, cleaned and sealed in Edinburgh city centre. As you can see from the photographs below the old sealer/wax coating had started to deteriorate and wear off in places leaving the table looking dirty and the client hated the waxy/yellow shine finish it left so asked us to remove the old seal completely and make the Limestone look completely natural.
Cleaning a Limestone Table Top
To remove the remaining wax coating the table was smothered in strong solution of Tile Doctor Pro-Clean which is an effective cleaning product that will strip off old sealers when used in a concentrated form. The solution was left to dwell for a while before being scrubbed in by hand and then rinsed off with water.
To make the job easier the table was cleaned in two sections and the process repeated a number of times in order to remove all the wax. Once complete the table was given a final clean using Tile Doctor Neutral Clean which is a PH neutral cleaning product to remove any trace of Pro-Clean and neutralise the stone before sealing.
Sealing a Limestone Table Top
The table was dried thoroughly before being sealed using three coats of Tile Doctor Colour Grow which is a penetrating sealer that soaks into the pores of the stone improving its natural colours and protecting it against staining from within.
The difference was remarkable and my client was delighted with the result.
