We were asked to take a look at a natural slate paving leading up to the entrance of a lovely old residence in North London. The slate path had only been recently laid, grouted and sealed and the owner was not best pleased with the results and a request was made to remedy the situation and return the slate back to its natural colour and appearance.

We carried out a series of tests to ensure we could remove both the sealer and grout haze from the surface of the tile. It’s not a good idea to apply a different sealer on top of an existing product as the end results will be inconsistent and the products maybe incompatible. We cleaned up the tile, sealed it and left it to weather for a few days to demonstrate to the customer the durability of the finish.

Cleaning Natural Slate Paving
All was well with the test and we got the green light to do the whole slate path. We started by cleaning the path with Tile Doctor Pro-Clean which was then washed off and allowed to dry. We then applied Tile Doctor Remove and Go mixed 50/50 with Tile Doctor NanoTech Ultra Clean; this is a really powerful combination which we left to dwell on the tile for an hour in order to soften up the current sealer and ingrained dirt. The solution was then removed and the slate tile washed down with more water.
Last step before sealing was to neutralise the floor with another rinse down, this time washing the tile with Tile Doctor Neutral Cleaner, it’s important that any remaining chemical is removed from the surface otherwise it may upset the sealer.
Sealing Natural Slate Paving
Finally once the slate had dried, we applied 3 coats of Tile Doctor Colour Grow and buffed off the last coat with a buffing pad to bring out the deep colour from within the Slate; the sealer was fully dry and path ready for normal use 12 hours. For maintenance we recommend using Tile Doctor Neutral Cleaner, diluted 1 to 30 with water applied with a microfibre flat mop, rinse with water and dry with second microfibre mop. The customer was very happy with the results and left the following message:
Robert’s communication was excellent and he always kept us informed on what to expect and the timescales involved. He was very reliable and punctual and the quality of his work was to a very high standard. We were very pleased with his work and overall service.
