 It may come as a surprise to many people that it’s common place for newly built extensions to get cracks. This occurs because of movement between the ground and the wall. But it’s just been built! I hear you cry. Whist we understand that it’s a pain to have to re-plaster and redecorate an area that’s just been built, it’s a job that’s got to be done. We empathise that paying out more money to fill the cracks is the last thing you will want to do, don't rush into this. We recommend that you wait at least a year before tackling the problem. The movement in a newly built extension takes place over a period of time and can affect various places. Settlement cracks can occur in the joint between the ceiling and wall. The weather and quality of materials used in your extension are determining factors of the severity of cracks seen in your walls and ceilings. So, if your extension is just a couple of months old and the sight of those cracks are driving you mad - get in touch! We can assess the damage and book you in to be seen in a few months’ time. This will give you peace of mind and time to allow any further cracks to appear.

 Sooner or later, almost every plaster wall and ceiling develops cracks - if not in the broader expanses, then at least where flat surfaces join one another. Wind pressure on the house, structural expansion and shrinkage, traffic vibration, and household activities all contribute toward weakened plaster. Before any redecoration can take place, the inevitable patching must always be done.
How to fix big cracks First, clean away all material that appears loose in and around the crack. If it's a fair-sized crack, crack to its deepest part, then undercut it so that it's wider underneath than on the outer surface. How to fix smaller cracks Little cracks can simply be brushed clean. With a spray, a sponge or rag, thoroughly dampen all surfaces of the crack. If this is overlooked, moisture from the new plaster will be absorbed into the wall, leaving the patch powdery and weak. Press the mix into the bottom of the crack, build up slightly more than necessary, smooth off the excess, and let it dry for 2 to 4 hours. Then use sandpaper to smooth off the excess. If you are going to paint later, a few strokes with fine-grit sandpaper will finish it off nicely. How to patch holes The general procedure for patching holes where plaster has fallen from the wall is the same as for patching cracks: undercutting, cleaning, dampening and applying new plaster. How to repair a bulge To repair a bulge, first create a hole where the bulge appears. Do this by rapping the bulge with a hammer until the loosened plaster falls out. Be sure to knock or pry away any loose plaster around the hole so as to have sound plaster at the edges of the patch. If you don't want to do the job yourself and you are looking for well-priced, professional and friendly plasterers in Redbridge, give us a call. Plasterer Redbridge covers east London and Essex, offering you our plastering, rendering and external wall insulation services. Get in touch on: 020 8088 0926  There's an art to plastering a wall well, and the use of the proper tools is essential. These include a plasterer's trowel, a corner-shaping tool, a hawk, a darby, a screeding rod, a brush and a bucket. To order the materials you will need, figure the size of the area to be covered. The undercoat is a mixture of sand, prepared gypsum plaster and water.
If this already sounds like hard work, let us take care of it for you. Call Plasterers Redbridge on 020 8088 0926. If you still want to give it a go, here are the tools that you will need. 1. Trowel: a plasterer's trowel is a must. This has a long brace bar on the top side. It costs a bit more for this trowel, but it's worth the price. 2. Hawk: this is the classic mortarboard device. Use one made of aluminum and save wear and tear on yourself. The wooden type is much heavier. Load with plaster and hold in the left hand while the right does the work (unless you're left-handed!) 3. Darby: a two-handled smoothing tool to level large flat areas. It is held flat against the wall as it is moved along and levels out any bumps. 4. Screeding Rod: a straight-edged wood or metal stick to level off rough plaster applications. One end is usually held against guides as the upper end scrapes excess plaster back onto board for reapplication. 5. Water Brush: this, and a bucket of clear water, must be kept on hand for finish plaster coating. The brush spreads as well as dashes water over the surface being troweled smooth. How to mix the plaster To mix, use either a wheelbarrow or shallow wood box and mix the sand and plaster, dry, in one end. Tilt the mixing box with the dry mixture in the upper end and put water in the low end. Then draw the mixed sand and plaster into the water a little at a time, mixing constantly. If water is added into the dry mix, or all of it is pulled into the water at once, lumps are formed which can't be easily broken up. Mix to a heavy creamy consistency. Add more of the dry mix or water, as necessary. Apply the base coat. The final coat of finishing plaster is mixed with water without sand and applied. Plaster is applied from a full trowel on upward strokes, using light pressure only. As you can see, plastering is a skill that needs to be mastered in order to have smooth walls that will bring years of pleasure. We don't recommend giving it a go, if you are not a handy and meticulous person.
