I am assuming you are a beginner at this so I would suggest that you aim to work on 8 - 10m 2 at a time, between grouting & cleaning. Mix a small amount of grout in the bucket for your first attempt, it is better to mix to little than to much on the first attempt as you will get a feel for how much water you will need for your second attempt at grouting slate tiles. Read the grout manufacturers label prior to mixing any grout. Now the sealer has dried you are ready to grout your slate floor, you will need a clean bucket, fresh water & your chosen device for mixing. So pour some sealer that you have been supplied with in to the painters tray & then lightly seal your slate tiles.ĭO NOT over apply the sealer, try to spread it well with the roller, you should easily get 12 - 15m 2 coverage for every 1 litre of sealer that you have, if it is over applied you will be left with blotches, so spread it evenly over the tiles but not to thick.īy sealing your slate tiles you are blocking the pores of the stone, this will then enable the grout to float over the pin head sized holes on the stone & not stick within the pores, the grout should now be easily removed when it is applied & you are now ready for grouting the slate tiles.Īll natural slate or stone needs to be sealed, do not try to save a few pounds by cutting corners & not sealing your slate tiles prior to grouting, you will be left with a hazy mist on the surface & you will find it practically impossible to remove, (TRUST ME, I HAVE SEEN IT HAPPEN). Before grouting your slate tiles you must seal them. Your now need to get your small sponge roller & painters tray, ready for the next phase. So we recommend leaving these types of slate for at least 24 - 48hrs at room temperature to ensure that all moisture has fully disappeared.
Well because these slate tiles have high salt & mineral content, so once wet, efflorescence (an unpleasant, cloudy/white blooming affect) can cause crystallization to occur which you will find almost impossible to rectify. If you have purchased Indian or Chinese Slate & especially black Chinese Slate, make 100% sure that these tiles are fully dried before you seal them, we have seen floors ruined by sealing damp or wet floors when using this slate. You must now let the floor fully dry & I would recommend that you leave it overnight to dry at room temperature. Doing this enables you to have a nice fresh clean floor when the water has dried off the surface ready for you to seal your slate tiles. Depending on how dirty the slate tiles are I recommend that you wash out your bucket & get fresh clean water when it begins becoming dirty.
#HOW TO CLEAN SLATE TILE HOW TO#
To do this you will need your bucket & large sponge as shown on (" How To Install & Installing Slate Tiles" guide).īegin by ¾ filling the bucket with clean luke warm water, then start from one end of the room wiping the surface of the tiles with a rinsed sponge, DO NOT saturate the floor. You are now ready for the next phase of the installation but before you can begin grouting slate tiles, you must first clean the floor & seal it. It is advisable at this stage to remove any debris or adhesive that may have oozed up between the grout joints or been left on the surface. Before you begin grouting your slate tiles & only when the adhesive is fully dried should you consider the next phase, if you do not let the adhesive dry fully you may experience lifting of your slate floor tiles after installation, they must fully bed & the adhesive must cure/dry properly.
