Replacing Mastic

End of Tenancy Shower Cubicle Renovation in Woking

Example below of the end of tenancy clean of a Ceramic tiled shower cubicle in Woking student accommodation. The Ceramic tile, grout and shower base were filthy. The mastic had perished, shrunk, and turned black. Unattractive and unhygienic the landlord had little chance of re-letting the property with the bathroom in that state, so we were asked to step in. As you can see from the pictures it was pretty bad although I have seen worse.

If you have a rental property with a stone floor its worth giving Tile Doctor a call as we find landlords rarely give tenants instructions on how to maintain them and they often end up in a state by the end of the lease.

Cleaning a Ceramic Tiled Shower Cubicle

Ceramic tiles are exceptionally durable and as long as the glaze is intact, they can usually be cleaned quite easily. Grout however is slightly porous and traps dirt which can be a struggle to clean effectively. The grout in this shower was discoloured and permanently stained so the best way to renovate it was to apply a grout colourant.

Before applying the grout colourant, I cleaned the grout with the Tile Doctor Grout Clean-Up and a wire brush. Being an acidic product, it can remove old grout smears, limescale, body soaps and fats, also being it will key the surface of the grout allowing for a superior bond with the grout colourant later.

Next, I cleaned the tiles using Tile Doctor Oxy-Gel which being gel based sticks well to vertical surfaces and allows for better dwell time so it can really eat into the dirt. The gel is applied to the tile, left for ten minutes, and then scrubbed it in with a 6-inch handheld polisher fitted with a black pad.

We then started on the shower base. I used Tile Doctor Remove and Go for this, again leaving it to soak into the surface dirt for ten minutes before scrubbing it in by hand with a brush. I managed to get into all the grooves in the plastic tray and removed all the dirt.

Once the cubicle was dry, I removed the mastic sealant from the two verticals and three horizontals around the base and behind the glass door. This is a fiddly job that can take a while with an assortment of knives and scrappers, taking care not to damage the tiles or the shower tray.

Now the shower was clean I coloured the grout back to its original white colour. This is tedious work carefully applying the colourant with a narrow paint brush. The product dries very quickly so any excess product the gets onto the tile must be wiped off immediately. Another advantage of using a grout colourant is it forms a barrier over the grout, sealing it prevent dirt from becoming attached to its cementitious surface. The smooth surface of the colourant also makes it much easier to clean.

Whilst the Tile Doctor Grout Colourant dried, I applied a new white mastic. Applying mastic takes some time to master and is best left to the experienced. It is not easily mastered but practice does makes perfect.

Once done the cubicle looked transformed. I managed to complete the shower by early afternoon advising my client that mastic needs 24 hours to dry before it can be used again. He was very happy, the shower cubicle looked as good as new and relieved it was in a rental condition again.
