What kind of sealant?

Question

Hi,I have a couple of garden slabs in the living room (long story why ... they act as loudspeaker bases).  Most likely they are the kind of cheap slabs shown on the site below (Riven-effect paving)  can I use to seal them, needing to achieve:(a) stop dust coming off them ... well there is more dust on them that comes off them but ... :-)(b) to protect them from being marked by e.g. a spilled coffee or red wine.Had they been wood I would have been using clear matt or soft sheen varnish for what I am trying to achieve.========================PVA glue would do the dust trick I think ... but as it is water based not sure it will protect from much else.Anything else?  (I spotted some Ronseal kind of sealant at B&Q, if the 1lt tin was in stock it would cost more than the two slabs but I am not sure I can figure it out on the Ronseal site).TIACharles

There is a sealant used for waterproofing brick  etc (outdoor) I think made by thompsons.Might do the trick.

An eccentric approach, but a number of companies are able to polish concrete - no more dust and a nice finish which I would imagine would be reasonably coffee proof. A polished result would take a coat of varnish quite nicely.

Alternatively, get a couple of marble or similar tiles which are already polished and need no treatment. If cost is your limiting factor, it might be cheaper to bin the dusty conrete for something that doesn't require additional work.

Tile sealant - eg

The Medway Handyman · Answer

Johnsons 'Clear' floor polish, available in most supermarkets. Water based acrylic seal mainly for vinyl, but should work on stone (try a small area first, terms & conditions apply, this call may be recorded, regulated by the FSI).

Marble is quite vulnerable stuff in terms of staining, and even requires careful choice of cleaners. Its also a lot less dense.

Almost any type of sealant would do, just avoid ones that redissolve and outdoor only products. So if you're not fussed about appearance, as I'm guessing is reasonably likely given the choice of concrete, then anything such as household gloss, floor varnish, furniture coatings, etc would do the job.

I would second that - Stain Stop is the product to go for IIRC. I remember Andy Hall describing its use on porous stone where he did not want to change the appearance of the stone.
