When the mason we appointed created pockmarks on the existing wall plaster to create a gripping surface for the layer of plaster of Paris (POP) to be applied, the existing plaster started coming off. At points it came off in clumps, at others it held up just enough to start the POP work. Has this happened due to lack of cement in the plaster? Should we redo it entirely, as suggested by the mason? We are already behind schedule. Will fixing murga jaali (chicken-wire mesh) on the existing surface help? How much extra would I have to pay for this?
The wall plaster will fall off in clumps only if it has not bound well with the wall. Redo the entire plaster. The approximate cost in a high-rise building is Rs8-10 per sq. ft for dismantling, and Rs12-18 per sq. ft for application of a 15mm thickness of plaster (1 part cement: 6 parts sand). Expect an 8-15% discount for plaster area more than 1,000 sq. ft. The additional time required would be one-two weeks (approximately), depending on the surface area to be covered, ambient room temperature and humidity.
The wall plaster could also dust off (rather than fall off in clumps) due to two conditions: inadequate cement quantity or inadequate curing (keeping the plaster moist until it achieves full strength). In both conditions, the plaster dusts off like dry sand when its surface is disturbed. You could redo the plaster or strengthen the existing surface with a brush application of cement-water slurry (also called cement-water “solution”) on the surface, curing it before applying the second coat, followed by a layer of POP.
Application of cement solution on the existing surface is recommended only if the plaster is slightly weak, and not if it is falling off in clumps. Moisten the existing plaster an hour before applying the cement slurry. The cost of cement slurry application is approximately Rs3-5 per sq. ft per coat. The additional time required will be approximately one or two days per coat.
Murga jaali or chicken-wire mesh is nailed to the existing (brick or plaster) surface to avoid shrinkage cracks that appear on the final plaster or POP surface when (a) excess water is used to make the plaster or POP paste; (b) the POP layer is very thick; or (c) the plaster and POP cover the junction between two different materials, such as a brick wall and RCC (reinforced cement concrete) column/beam. The wire mesh provides nominal reinforcement to the plaster, similar to mixing in metal or polymer fibre, easily available in the market today. The cost is approximately Rs8-12 per sq. ft. However, this will not help if the underside of the plaster is weak, and is coming off in clumps. The additional time required would be approximately one or two days.
We want our basement wall to be 6 inches of RCC, plus a brick wall inside, but our consultant is insisting on a 13-inch brick wall on three sides, with RCC plus brick on only one side, which is all that is required, according to him. What should we do?
An RCC wall is recommended with a (column-beam) frame structure as it helps to tie the building frame together better, even if a raft foundation is not being employed. A 13.5-inch brick wall, on the other hand, is all right if it touches the basement wall of the adjoining house and no thrust is expected on its surface.
Though not waterproof by itself, RCC will help if you want to use a pressure grouting technique for waterproofing. Chase-cutting for electrical and plumbing pipes is not recommended in an RCC wall, therefore a 4.5-inch brick wall can be erected along its inner face to accommodate those. This inner brick wall could also be erected before casting the RCC wall. This way, the thin brick “skin” binds well to the RCC. The only problem with this is that you will never be able to see any honeycombing (hollow spaces) in the embedded RCC wall, so repairing it becomes a challenge.
For walls erected along the free edge of your plot, with no adjoining house to support the RCC on the other side, the RCC wall can be embedded between two 4.5-inch brick walls, so that these ultimately sit on either side of the RCC core.

Wire mesh panel systems are available in several different styles
Mesh fencing is normally intended as general boundary fencing to either keep people out of a given area or to keep them in for security purposes. This type of fencing can also be used in rural areas to contain wildlife and even at small zoos for enclosures of small animals such as monkeys, gerbils and birds etc.
Mesh fencing systems are most often used as a perimeter fence for industrial or commercial purposes. This type of fencing provides a more aesthetically pleasing appearance, and will provide privacy, security and durability; it is cost effective and more attractive than the typical alternatives. Some mesh fencing is designed with roll top and roll bottom, and this is considered to be user friendly, and also add safety and extra rigidity.
Wire mesh panel systems are available in several different styles and colors to suit various types of applications, and robust welded mesh panel systems are used in a variety of applications high security is not a major requirement. This type of fence has very low maintenance costs owing to the strength of the panel and the coated finish for a long life.
A typical panel will consist of Intersections with reinforcing folds of horizontal and vertical wires and at these wire panels will be welded to the intersections.
The weld strength will be 75% of the minimum tensile strength of the wire, and the opening will be 200 x 50mm in the folded areas. The wire diameter is 4mm but may also be 6mm if required.
The posts are constructed from rectangular hollow section and will be capped with either plastic or optional welded steel post caps.
Other post options may include:
• Base plates or dowels
• Plates for mounting on walls
• Base plates for fixing to concrete or top of walls
• Cranked extensions to receive mesh panels
• Doglegged cranks at base to rise above walls
The finish of these panels may be color coated in black or green, but other colors are available.
Other types of mesh fencing can include insect and fly screen mesh which is extremely fine with very small holes and is generally manufactured from plastic, stainless steel or aluminum.
Monofilament netting is another type of mesh, and this is used for the protection of plants and crops, and it can also be used to protect fish from predators as well as being effective at keeping out leaves.

Metal Spray Guard protects from dangerous spray-outs..................
Stainless steel spray guard protects from dangerous spray-outs of fuel oils such as kerosene, diesel, and other flammable liquids from pipes and flanges. Pressure tested up to 50 bar, TUV approved shield features quick-release connection, and does not require tools or knots to be tied. Safety shield has steel band and internal SS mesh that wraps around flanges and valves. Mesh sits against flange, between it and outer steel band and compresses against it to disperse sprays or leaks.
A new type of TUV approved stainless steel spray guard which provides effective protection from dangerous spray-outs of fuel oils such as kerosene, diesel and other flammable liquids from pipes and flanges, has recently been introduced by level and flow specialists ALLISON ENGINEERING.
The innovative design of the Allison safety shield incorporates a steel band and an internal stainless steel mesh which wraps around flanges and valves. This mesh is designed to sit against the flange, between it and an outer steel band and compresses against it to ensure that sprays or leaks are dispersed, whilst also preventing lateral spray. The mesh acts as a seal which is 'pinched' in the middle to form a raised layer that squeezes in the small gap between the two flange faces.
The shield, which is TUV approved and has been pressure tested up to 50 bar, has a quick-release connection, it does not require tools or any knots to be tied, so installation and removal is quick and simple. It provides effective spray control on most flange configurations, round, oval or square and regardless of the flange gap, the internal stainless mesh adapts accordingly.
