Bonding can be applied to really dense concrete blocks or engineering bricks and even concrete itself. Browning Plaster: Browning plaster is also an undercoat plaster for use on more absorbent surfaces.
Hardwall Plaster: Hardwall is similar to Browning except that it offers a higher impact resistance and quicker drying surface.
Tough Coat Plaster: Even tougher than Hardwall as an undercoat plaster, and has a greater coverage based on the nominal depth of 11mm. Dri-Coat Plaster: Dri-coat plaster is a cement-based plaster used when resurfacing a wall after installation of a new DPC.
Multi-Finish Plaster: Thistle multifinish is a top coat plaster which is suitable for a great finish on all the other surfaces.
One Coat Plaster: Sometimes called patching plaster, this plaster is a mix of something like binding plaster and multifinish. The consistency is up to you and we advise experimenting by mixing separate piles to see how you like it. When it is hard, and bumpy, there is absolutely nothing you can do with it except chop it off or plaster right over it.
Clean cold water should be put in the bucket first to about one third of the depth then finishing plaster tipped in gently, until the heap rises above the surface of the water. The paddle, on a low speed, should then be placed in the bucket and moved up and down, and side to side, to mix the plaster.
Always have another bucket of water close, to you so that you can clean off your tools immediately.
For novice plasterers the same technique can be used to divide the wall into manageable sections to plaster. If you have any external corners to negotiate, external angle beads can be fixed in position to make these easier for you.
Ideally both coats of plaster should measure 3mm thick and if the wall is the correct, consistent thickness it will dry out uniformly, with no cracks.
Before you start to apply plaster, damp the wall down with a large emulsion brush and water. Take a straight edge (metal is better than timber) and lay it over the two beads at the bottom of the section you have filled.
Scrape the plaster off the straight edge back into the bucket and go back to your hawk and trowel, fill the holes and any areas that may be a little low.
You will feel the surface go smooth under your touch and after a while you should be able to sense any depressions or high spots in the wall. There is a great variety of small tools to get into various nooks and crannies around the house, and all are available from good tool stores. If you have fixed angle beads to any external corners, the undercoat plaster should finish just below the tip of the angle. Take a nail, or a small screwdriver, and drag it lightly, in a coil shape, over the surface of the plaster. If 3 or more hours have passed between undercoat and top coat, it’s a good idea to damp the wall down again. Each pass on the hardening plaster should see more and more trowel marks and bumps disappearing. Exactly the same method is used to fill patches of wall which need plastering only, instead of using metal beads as a guide to depth, you use the side of the hole you are patching.

Work over the whole area aiming to apply a base coat a€“ dona€™t worry about any uneven areas or holes at this stage.
The next stage is to level and smooth the surface but this can only be done when the plaster has hardened slightly but is still pliable. How to skim plaster and plastering a base or undercoat before skimming or top coat plastering. The technique is important of course, and we will outline that here, but this is another of those jobs where practice is invaluable. They are the plasters a plasterer will use and if it’s good enough for the pros, it's good enough for the DIY enthusiast. This means it is the first coat, or undercoat to be applied to a new (or to be patched) wall. It is the most often used undercoat plaster these days, and can be applied to most masonry surfaces. Multifinish is ideal for (indeed, is manufactured for) using as a finishing plaster when there are a variety of backing surfaces to be covered. Once on the wall this plaster can be trowelled up to a very smooth finish and no further application is required. The average mix of finish plaster will be on a medium suction surface for approximately 10 minutes before it starts to go hard. It’s obviously important to get it right and this can only be achieved with practice.
Builder’s merchants can supply you with 10mm plaster stop beads which you simply fix to the wall. Stop beads can also be bought at 3mm thick for application and division of the finish coat. The scratch should be no more than 1mm deep and all of the wall should be covered with no more than 150mm between any of the scratches. Again, this has to be to a certain consistancy, that of thick porridge and when layed on a flat surface should be self-supporting. Try to get the plaster to an approximate even thickness, but do not spend time trying to get it perfectly flat at this stage.

No matter how hard we have tried over the years we cannot get as good a finish with One Coat as we can with two coat plaster work.

If you mix a new batch of plaster and there is still some of the old remaining on any of the tools, it will go hard much quicker. The beads can be fixed by placing a few small dabs of plaster on the wall and pushing the bead into it. Repeat the process a couple of times until the section is full, flat and relatively smooth. Rub over the wall lightly once more with your plastic float just to flatten out the burrs caused by the scratching. Ita€™s essential to mix the powder and water thoroughly so that you have a thickish, creamy consistency with no lumps. Keep your trowel wrist straight and use a flicking action with your a€?hawk handa€™ to move the plaster from hawk to trowel. Use your trowel at a very shallow angle to the wall and work over the surface smoothing the surface. The important thing to remember is to add the plaster to the water, not the water to the plaster. Also, a plane plaster surface must be flat enough to appear flat to the eye and receive surface-applied materials, such as casings and other trim, without the appearance of noticeable spaces.
If the trowel is flattened against the surface it may pull the new plaster away from the wall. The idea is to provide just enough lubrication for your trowel to float over the surface and fill tiny holes and imperfections.
This means getting the plastic float and rubbing in a circular motion over the wall to close any fissures still remaining.
The shape and size of the trowel blade are determined by the purpose for which the tool is used and the manner of using it.
This is the first tool used in leveling and straightening applied plaster between the grounds. In a worm-drive machine, mixed plaster is fed into a hopper and forced through the hose to the nozzle by the screw action of a rotor and stator assembly in the neck of the machine.
A machine of this type has a hopper capacity of from 3 to 5 cubic feet and can deliver from 0.5 to 2 cubic feet of plaster per minute. On a piston-pump machine, a hydraulic, air-operated, or mechanically operated piston supplies the force for moving the wet plaster. On a hand-hopper machine, the dry ingredients are placed in a hand-held hopper just above the nozzle. The plasterers, under the crew leader’s supervision, set all levels and lines and apply and finish the plaster. The tenders mix the plaster, deliver it to the plasterers, construct scaffolds, handle materials, and do cleanup tasks.
This extra floating is required to increase the density of the slab and to fill in any cracks that may have developed because of shrinkage of the plaster. Pressure on the trowel must be sufficient to force the material into the rough surface of the base coat to ensure a good bond.
As the plaster begins to set, the surface-water glaze disappears and the surface becomes dull. The plasterer holds the water brush in one hand and the trowel in the other, so troweling can be done immediately after water is brushed on.
Preliminary finishing of portland cement-sand is done with a wood float, after which the steel trowel is used. To avoid excessive drawing of fines to the surface, delay troweling of the portland cement-sand as long as possible.
It produces a fairly coarse finish that can be modified by brushing the plaster with water before it sets. As the plaster begins to set, it is troweled intermittentl y to form a pattern of rough and smooth areas.
