Try this, with thanks to 'Patrick': Thesis on Plastering - oh Boy! Jim, and anyone else who feels it necessary to attempt plastering, please read on: I started my life as an electrician and have been in the building industry for a long time, graduating to running my own house building company, so I've probably seen it all and done most of it. These days I renovate houses for a hobby and, apart from carpet fitting and plastering, I do it all myself. I recently decided to alter one of our own bedrooms by putting a shower in and wardrobes etc. This room hadn't been touched for about forty years and consequently required a good seeing to. At the end of the first days work, stripping wallpaper, drinking tea, scratching my backside and generally getting to know the job I, and my beloved, sat down for a glass of champagne (as you do)! After two thirds of three bottles or so she said "Why don't we take out the ceiling and expose the beams" After two thirds of three bottles or so I thought this was a tremendous idea and committed myself wholeheartedly. Next day I raided the medicine chest, ate the aspro and set to work. Down came the ceiling and resplendent before our very eyes was the entire underside of the stone slate roof. Four 12 x 12 partly adzed oak purlins, one humungous truss and a deep deep sense of misgiving. From floor to apex is approximately eighteen feet and the room is in the region of eighteen feet long and sixteen feet wide. Another alteration in this room called for a door to be moved from one side of the central chimney stack to the other. There were vast quantities of old plaster which sought refugee status from the walls and hid in one of the skips I had thoughtfully placed outside the bedroom window. In short, there was going to be a lot of plastering to do. Now; I no longer earn my keep by building trade activities and consequently I am practicing my hobby evenings and weekends. Also, now that I am getting very old and passion, that ravenous beast, no longer rears its ugly head as often (apologies to Roger McGough), I find that one of life's enjoyments is doing my own stuff from start to finish (or start to carpets in my case). Also, even though I know a lot of them, actually getting a Spread to come and do the plastering would be logistically difficult. By nature I am a tight *******, a sad ******* and very probably a demented one (Man City fan, say no more) to. I decided that for the first time in my life, I am going to plaster this lot and sod the consequences. So this is what I did, and you may wish to do too: First things first. You've never been beaten yet and you're not going to start now. This may seem trite under the circumstances, and as you progress down the gypsum road you'll deny thrice (or more) that you ever said it. But keep it in the back of your mind. Your particular job, Jim lad, involves a brick wall, which involves a base or roughing coat interspersed with a banging your head against it coat followed by a finish coat or skim. If you're lucky you'll omit the middle coat but don't hold your breath. Base or Roughing. This involves one of several materials, all of which do the same job. They provide a base upon which you put your finish/skim coat. Its object is to provide a reasonably level background and as such is not meant to be smooth. You just have to get it reasonably flat, with as few undulations as possible and hopefully without any craters. With a brick wall the best (IMO) roughing coat is Carlite Browning. This comes in large bags which will test your scrotum elasticity coefficient but which will normally not damage it too greatly. Lay the bag flat on the floor, get a Stanley knife and cut it open like a, well like a bag of plaster actually. Whilst you are at B&Q buying this here plaster, also get yourself a plastic bath to mix it in. You don't want to be mixing this stuff on the floor, you will need a container. Plastic baths cost about fifteen squid or so. The delicate shade of blue they're manufactured in makes them very handy for the new bathroom renovations later in the year too! Now, put about five - no more - shovel loads of said browning into the bath. Make sure you have at least two buckets of water handy and pour about half of one bucket into the bath with the plaster. With the front and then the back of the shovel, move the plaster through the water, back and forth, back and forth until the water and plaster have meta.. metamor. changed into an unpleasant half wet half dry mixture. At this stage start to pick it up with the shovel and drop it back down on itself. i.e. mix it. You won't have added enough water at this stage so start to add more, slowly until you have a mix resembling a stiff chicken madras without the chicken. A bit like a very thick whipped cream. At this point the stuff is going to start out on it's hour long journey into rigidity so, time is now of the essence! If you've not done this before you'll soon discover the one thing you haven't got is speed. You'll be slow and clumsy, you won't believe it's possible that this stuff will stick to the wall and you'll begin to wonder how you can abandon ship and save face at the same time. Courage mon ami, pretend it's your first lover. Remember how nothing was going to stop you then and it isn't going to stop you now. Take a shovel load of the mix and slop it onto your ligger board. (At least in this part of the world it's called a ligger board. Don't know what it is where you are but, regardless of name, this is a piece of flat stuff -22mm MDF is as good as anything- about 3 feet square and placed at or about waist height (Do not, under any circumstances use something she cherishes to stand it on)). Next with your hawk (I guess you do have one of these, it's a square piece of metal or plastic on a short stick??) in your left hand (or right hand if you're cuddy-wifted) and your trowel in the other hand, push a glob of muck (technical expressions tend to creep in) onto the hawk, about the size of a right hand 48dd (ask the wife if you're unsure). When it's on the hawk, slide your trowel at an angle of 45 degrees, underneath it, lift it about four inches into the air and drop it back on the hawk. Do this a few times until you've got the feel for it. I'm not quite sure what the benefits to the job are but it feels good to do and lets the muck know you're the boss. It also produces a very neat rugby-ball shaped pasty on the hawk. Casual passers by will be enthralled and only you and I will really know the truth. I digress. Now, approach the wall and God at the same time. The wall is about to be transformed, God probably doesn't give a damn but you might just get lucky. The object is to get this stuff in a fairly even and flat layer all over the wall. Unless you're a natural born or just get lucky you're going to need a little help to achieve this. Some guys advise putting thin wooden battens, vertically on the wall and then using them as a kind of former by rubbing a levelling stick across them and scooping off excess plaster. This is a good method but, if you can manage it, substitute these battens by using plaster. To do this; when you're at the wall, bend your knees and scoop about half the rugby ball pasty which is now sitting on your hawk onto your trowel. The best way to do this is to hold your hawk slightly towards you and, with the bottom edge of the trowel, scoop away and upwards with a twist of the wrist at the last minute so that you finish up with a trowel, flat side up, with a big wodge of fresh muck on it. (I've found it's best to pretend you do this all the time because if you so much as flicker an eye, the muck will find out you're a charlatan and leap onto the floor). If it does this, don't worry, just try again. If your floor is fairly clean you can scoop up the spills and re-use them. (This doesn't apply to skimming though). Once you have the muck on the trowel, push it against the bottom of the wall (not quite touching the floor) and slide the trowel upwards, making sure you hold the top edge of the trowel slightly further away from the wall than the bottom edge. The muck will leave the trowel and stick to the wall. Do this till you run out of plaster on the trowel then repeat with fresh stuff until you have a trowel width of muck all the way up the wall. Repeat this a yard or so to the right and then the left. Repeat until you have vertical lines of muck up the wall about a yard or so apart and no muck left on your ligger. At this point your plaster is hopefully still workable (you'll see what I mean about speed at this point) so get a straight edge and place it vertically against the plaster strips and try to level them off so they're about a quarter to half an inch thick all the way up. If you need to add bits of muck, add them, play about with it, you're the boss! When you have them roughly in the required condition, leave them alone. Go and have a recreational moment (preferably involving the wife because you're going to need her sense of humour soon) and come back after about half an hour. Before you go off though you must, repeat must, repeat must clean your bath, your hawk, your trowel and your shovel. A bucket of water and a hand brush will be invaluable here. Under no circumstances neglect this because you'll regret it if you do. OK. Much refreshed , or not as the case may be, we're back. Do another mix in your clean bath with your clean shovel. About the same amount as before, or less if you feel that was too much. Practice the art of muck chucking and rugby ball pasty making again to increase your confidence level, fill up your hawk and return to the wall. Start to spread the muck between two of the vertical strips. Fill it up, proud if you can, all the way to the top. By this time the strips will be hard enough to be masquerading as formers, so get a feathered straight edge and, starting at the bottom place the straight edge across the enclosing strips and in a sawing motion move the straight edge from side to side and up from bottom to top. Place the excess back on the ligger. Look at the job. You'll probably see bits you've missed, probably all over the place. No worry. Just fill them, saw them, look at them. Fill them, saw them, look at them. Pretty soon you won't have any holes, just a reasonably flat surface between the strips. Do it again and again until you have a wall with a roughing coat on it. Congratulations. Wait for half an hour to an hour and with the corner of your trowel scratch a diamond pattern on it so you have a key for the skim coat. Oo's a clever boy then? Take the rest of the day off (it's probably ten o'clock in the evening by this time anyway) and next day we'll skim it. Just like this: If you've used Carlite Browning or any of the light weight roughing plasters you will probably be as well using Carlite Finish. Same scrotum elasticity coefficient as before but a much finer consistency of muck and a bit of a bugger if you don't watch it. You will need two buckets, one for water and one for mixing, a hawk, a plasterer's trowel, a gauging trowel, a mixing whisk and electric drill, clothes you can throw away this evening (or whenever you finish) and a hand brush, preferably with soft pier sava (spelling?) bristles. If you have left the roughing for more than a couple of days, get a garden spray, wet it down and allow it to soak in a little. I'm not sure this is essential because I've seen Spreads just walk in and do dry walls but it felt better to me. The object of this exercise is to put two coats of skim onto the rough. The first coat fills in the small holes in the rough backing coat and gives a key to the second coat which is applied second (funnily enough) and then 'polished'. Don't even consider doing it in one coat. It's no fun and anyway you could catch a cold (sorry). With skim coats, cleanliness is essential. As is a consistency of mix. The last thing you want is bits of dirt or lumps of unmixed plaster in your skimming. Start by putting clean water into a clean bucket. I wouldn't put more than two inches in the bottom of a standard builders bucket to start with. When you've done this, start to add your plaster using a small shovel or scoop. One scoop, mix with the whisk (incidentally you can get these from decent hardware shops or screw fix for about a fiver and they're absolutely essential unless you have arms like Arnie) until it's dissolved and then add another scoop, mix and so on until you have about a third of a bucket of gloopy pink (or grey) muck in the bucket. Don't get carried away and mix too much, you'll just finish up throwing it away. Now, with the aid of the gauging trowel and gravity, tip the muck onto your ligger. Unless you have a labourer (remember the advice about recreation and the wife?) stop at this point and quickly clean the bucket, whisk and anything else that has plaster on it. Do not skip this under any circumstances. You now repeat the picking up, slopping down, rugby ball pasty making exercise you started with yesterday. This time however the muck is much finer, slippier, sloppier and altogether livelier than yesterday. Persevere, it's essential you utilise your superior intellect to subdue the material and get it to do what you want. Word of warning though. Skim is the knee trembler of gypsum and it's going 'off' quicker than you think, so subdue it quickly and with panache. With the pasty on your hawk approach the wall and with the same knee bend, but this time at the bottom left hand side of the wall (unless you're cuddy-wifted), same flick of the wrist, same curse, as most of it (but not all), goes on the floor, get some onto your trowel. Push the trowel against the wall and in an arcing motion, just spread it. All you're doing in this exercise is getting a thin coat onto the wall. As long as it covers it, it'll do. Depending on how large an area your wall is I would be careful about trying to do it all at once. If you can first coat an area approximately four feet square I think you'll have done well. The problem again is going to be speed. You're going to have to get a second coat on before the first one has gone completely hard and only practical experience is going to tell you how big this area can be. Don't be tempted to try and get this first coat looking like a mirror, it just has to cover and key. It's the second coat where your skill will really shine through. This is how: Mix about the same amount again, same rituals and prayers, same steely determination. Start in the same place and apply the second coat, about 2 - 3 mm thick if you can. Again at this stage all you're doing is covering but try not to get too many 'craters' in it. If you are doing, just spread a little more on. Keep looking at it (but not to the exclusion of doing it) and you'll soon get the hang of it. When you've covered your first coat, leave it for about ten or fifteen minutes. Clean your tackle while you're waiting. Now with clean hawk in left hand, clean trowel in right (or not, if you're cuddy-wifted), clean bucket of water on floor and clean brush in said bucket, set to work. Using the edge of the trowel held at an angle of approximately 40 degs to the wall, drag it over the plaster. You'll soon see what the effect is. Either it'll gouge out a trough in the newly applied plaster or it'll remove the application marks and start to smooth it out for you (exciting). If the former, the plaster is probably too un-set so wait another ten, if the latter; keep going lad, you'll soon be on the vinegars! It's now a question of edge troweling until its all nice and smooth. The longer you go on, the harder the plaster is getting and the smoother your finish is becoming. If it goes off too much, don't fret, dip the brush in the water bucket, splash it on the area you're polishing and it'll buy you some time. Scrape, place on your hawk and re-use as necessary any plaster that comes off to fill any craters you may have. Apart from being on the knackered side you should now start to be experiencing a rather heady feeling of achievement. You'll be finding out how to do the edges and corners and amazed at how much pressure you can apply and still keep a smooth surface. Don't worry too much about the thin lines appearing at the edge of the trowel, these are mostly water lines and will disappear. If they don't, a quick once over with the a sander after your first coat of emulsion will cure them. Finally. Clean your tackle, open the champagne and lead your chariots into Rome. Best of luck.

does anyone know of a video showing basic plastering,just board finish skimming will do,thanks As a professional plasterer you would expect to earn a minimum of plus 100k per annum working from a home based office with very low overheads. Rough estimate of annual pay is half the hourly x 1000. "Expect" to find enough work for 4 months in the year at those rates. And if the low overheads do not include a maid for ravishing/tea supplying it is not worth it. Most of the problem with finding customers is that all of the effort is in preparation. Any fool can plaster a simple wall. Consider the problems of stair wells and old houses, nitches and alcoves, property where the occupier is a pain in the arse and poor payers. Then there is the building site where stuff goes missing, doesn't arrive on time or the plumber, electrician, joiner and half a dozen other idiots have not finished their bit, nor done the job properly and by and large you get an idea the job is not what you might have hoped for. That's not counting your own ****-ups. -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |
