I used to do it with DS but DD hates to be messy/dirty so haven't done it very much with her, I really need to start doing more to help her get over this dislike of touching anything non-solid. She's 17mo.
What about doing messy play in the kitchen? It's where I go because it can be mopped/wiped. Check out some local playgroups too, one of ours does a rota where one week they bake, the next they do messy play, the next is painting, the next is gluing/stickers then back to baking - that would save you the bother of setting things up and cleaning them up afterwards!
Gloop is an easy one. In a big dish or baking tray (or even a paddling pool or baby bath if you're feeking ambitious!) mix together cornflour and water until you get a yoghurty consistency. Squash some in your hands and it'll feel solid, relax your hands and it turns back to liquid. Hours of fun!
Baked beans, tinned tomatoes or spaghetti (smart price and the like are pennies a tin) on a plastic sheet (Poundland) are good too, and edible in case of any tasting. Just roll the sheet up and throw away after.
Dried pasta shapes or cornflakes in a tub. Also cooked strands of spaghetti.
A roll of paper (Wilkos have rolls of drawing paper) and saucers of paint but no brushes for finger/arm/hand/foot painting.
Baby bath on the floor of either the bathroom or kitchen, put a couple of towels under it to stop the floor getting too slippy. Put in a few inches of water and add bubbles, glitter, whatever you like, and some cups and spoons for splashy water play.
Playdoh isn't very messy but is good for touching and squishing.
