Levelling garage floor

[Ceri JC]

I'm finally drawing to the end of my extensive DIY garage rennovations. Due to not being able to use concrete sealant and garage floor paint on self levelling screed, I opted to level out the worst of the (rather significant) dips and troughs just using cement. This has worked fairly well and the seal around the door is much better now. Something I am left with are slight ripples and ridges in the surface where I smoothed it flat. They're not too big and I could live with them, but if possible I'd like to get rid of them or reduce them.

I have 2 questions:
1) Is it realistic to think I'll be able to "smooth out" these ridges/ripples using a stone grinding disc?
2) Is it possible to get stone grinding (not cutting) discs for 115mm angle grinders? B&Q only seem to carry sanding, metal cutting, metal grinding and stone cutting discs. Focus don't seem to do them either. Anyone know of anywhere online that does them (google searches are just throwing up packs of discs suitable for "cutting stone, grinding metal")? Links would be most appreciated.

Thanks in advance as always, .org.

I used tile leveling compound,mixed it really watery and poured it out and let it find its own level.going to paint it this summer.

1 = No
2 = They're the same thing, just a different term used depending on the material.

Get a bag of self-levelling compound from Wickes, mix it up real thin (as it says on the packet, it should be almost like water), and pour it over the floor. Leave it for 24 hours to set and you'll have the flattest floor you can imagine :-)

You have a PM :)

Are you sure? I've definately (already) got/used seperate metal cutting/grinding discs. They cutting one even has a warning on it that it's not to be used for grinding! Seems to make sense as the cutting discs are very thin (for making thin cuts :)) whilst the grinding discs are about 3 times as thick, presumably so they don't splinter when tilting them into the floor. The only time I managed to jag up the edge of a (stone) cutting disc was when I was trying to use it for grinding.

I suppose your answer to 1 renders this irrelevant, mind. ;)

Yes you can get 115mm stone grinding discs (6mm thick), like this (http://www.screwfix.com/prods/48861/Abrasives/Stone-Cutting-Grinding/Stone-Grinding-Discs/Stone-Grinding-Discs-115x6x22mm), however from them the p&p for just one item makes it silly. Try a builders merchants.

Metal and stone cutting abrasives are very different, they don't work on the other material very well at all.

I was going to leap in and recommend one of these (http://www.screwfix.com/prods/75459/Abrasives/Other-Cutting-Grinding/Grinding-Cups/Erbauer-Diamond-Grinding-Cup-100mm) , but embee managed to beat me to it. It's more suitable for your purpose though and cheap enough.


I would however suggest that you find their nearest trade counter and just pop in for one.
