Polycell LS500 500ml Liquid Sanding

I used a similar product to this for my garage doors a couple of years back. I switched to this brand with some hesitation, as not all the reviews are that positive. I needn't have worried.I would disagree that its the equivalent of using cream cleaner. For a start, if you spill it on the carpet - which I did - it does something very different to a cream cleaner e.g. it ruins it! So, whatever is in this product, it must have some power?I apply it with a dry cloth over palm-sized area, then pour some more out and continue in this way. It dries very quickly, but I think you have to use it reasonably thickly.I did a door frame in this way in about 12 minutes. The bottle says you should then leave it on for 15 minutes, but the Dulux website says to leave it on for 30 minutes. I left mine on for about 2 hours.When you return to wash the stuff off, you can immediately feel the paint is very rough to touch. As you wash it off, shine does return, which is a bit alarming, because you want a matt surface. However, and its a BIG however, if you run your fingers over the surface you can tell it is super, super squeaky clean and in parts looks quite matt. If your finger cannot brush over the surface easily, you know you've achieved the elusive 'key', and your fresh paint will adhere to the surface.I then painted over old solvent paint with water-based undercoat (for wood and metal) and dried it all in under 30 minutes with the assistance of my little fan heater. (The fan heater also helps to reduce brush marks.)Before I applied a second coat of undercoat the following weekend, I tested the strength of the paint's adhesion in various areas. Pleased to say, the paint is stuck down thoroughly and there is no chance of chipping it off, or skimming it away if you brush your nail along it. So, Voila! I would say its about 85% less elbow grease than previous paint prep jobs.Can't wait to apply my water-based gloss and dry that in a mere half hour too. I know the shine is not going to be quite as deep as old-fashioned solvent-based gloss, but I've seen some doors recently completed in this way by a professional decorator, and I thought the shine was very glossy, for an acrylic.P.S. The Americans have been using this stuff for years.Update 07/03/14:Started on a couple of radiators. Applied this product and forgot about it. Unknown to me, someone turned on the heating for a short while. Panicked, as I saw that the solution had become discoloured on the radiator? Turned the radiator off and quickly wiped the chemical off, thoroughly. The strange thing was, that the heat had actually helped the product to work even harder? this meant the topcoat was abraded with next to no effort from me. Thought in future I'd apply heat similarly, say with a hair-dryer, especially on jobs that are going to need a lot more time.Update 25/03/14:Started prepping the front door. Dealing with a lot of flaking paint, so had to use my Bosch sander for the rough bits. Decided to tackle the larger areas with this stuff, coz I know it will save me a lot of work. Using solvent paints on the front door, not because I want to but because I've got a load leftover from last time. Old paint can last for years if its kept frost free and has a seal round the lid e.g. when you've finished and put the lid back on, turn it upside down once.

I bought this to remove the dark varnish from the edges of a chest of drawers that I was stripping. The edging has a lot of ridges and I'm not good enough with sandpaper that I felt confident that I wouldn't destroy the detailing. So, after reading a couple of reviews (and having liquid sandpaper recommended by a DIY nut) I bought this. Polycell is usually a good brand and it was cheaper on Amazon than a certain DIY superstore. I used it this weekend and I have to say I was pleasantly surprised. I expected to have to employ a great deal of elbow grease after leaving it for ages but I didn't. I think I used about a quarter of the bottle but that's only because I painted it over the flat surfaces as well just to get rid of any stubborn bits of varnish left over from the sander. I applied it with an old brush over a few sections and then went back to first one to wipe it off, probably leaving it on between 5 - 10 minutes. It was quite easy - pretty much just like cleaning/polishing. It took a while to wipe off because the wood had been stained and THEN varnished so I just kept rinsing my cloth and wiping until the cloth came away clear. When the surfaces dried they were smooth and varnish-free. I'd definitely recommend this, particularly for detailing.

All in all am effective product. I have used this a number of times now. Fair price, but cheaper elsewhere so used Amazon because of free one day delivery.I've used it on an ornate picture rail, doors and skirting as hate conventional sanding. My main gripe is that once applied, it does seem to take a lot of effort to remove all traces. On one occasion a bit of residue was left, and this caused the applied paint to bubble and peel off. Lesson learned, I wipe it off, let it dry and wipe again three or four times until the residue has gone.Once done, paint adheres well, as though you've sanded the wood.

I used this on a very large highly /varnished / polished antique sideboard more like a French polish finish rather than a normal household varnish finish it was thick varnish and very shiny you could see your reflection in it. suprisingly I t worked and the paint adhered beautifully ( chalk paint) even after a vigorous wax paint didn't budge So thumbs up. The reason for 4 stars is it took ages with applying and washing off would be better for small jobs not big ones I would've done it quicker using a sander however glad I didn't have to deal with the dust. I would use it again but on smaller projects. So it worked well as a de glosser for varnish

I spent a day sanding down the skirting boards getting covered in dust and ran out of sandpaper so I bought this as an alternative to finish the last bit and yo do the door. WOW! Brushed this on the door in circular motion as directed, left it an hour and came back thinking it didn't look like it had worked. When I began to wash it with water it dragged off loads of pain and has left the door with a nice thin grain rough feel that will take paint really well. I will be doing the staircase using this stuff! It's messy but save hassle and better than getting dust everywhere

Das Produkt hilft leider gar nicht. Es ist einfach wie eine teure Scheuermilch. Man muss eben doch mit einem schwingschleifer ran und verschiedenen Körnungen. Ich kann dieses Produkt gar nicht empfehlen.
