ACOUSTIC SOUND BOARDS
Acoustic sound boards are an ideal treatment for those noisy neighbours who may as well be in the same room as you, at only 22.5mm thick acoustic panels offers extremely good levels of sound insulation when added to brick or stud walls. The panels are constructed from 12.5mm acoustic plasterboard and a composite panel of an acoustic foam layer sandwiched between two layers of a high density acoustic membrane, the panels composition means sound transferring through the wall is blocked and absorbed at the same time due to the combination of acoustic foam and the density of the product, soundproofing a wall against noisy neighbours with acoustic sound panel is an ideal solution.
Render is applied to the external walls of houses and garden/boundary walls as a smooth or textured decor able surface. Render is produced by mixing Sand /plastering sand, cement and hydrated lime together with water and or with mortar plasticiser. Render is applied in two coats using a hawk and trowel. The first coat is called the ‘scratch coat’ and the second is called the ‘top coat’. The scratch coat is left to settle and dry for 24 hours (depending on weather conditions). The top coat is then applied and ‘ruled off using a straight edge, this helps take away any high points and gives a flat appearance ready for floating over and finishing off with the magic sponge.
Dry lining refers to the process used when attaching plaster based sheet boards to either a wooden stud framework, metal stud work or direct to brick or block work using an adhesive compound in a process called dot & dab. It is popular on both new build applications and refurbishments projects, there are many different types of board used in dry lining, each one suited to a particular purpose or need from standard plasterboard to specific needs Boards.
Wet plastering, known as float and set refers to the process of applying a wet plaster base to the substrate surface before the finish or skim coat is applied. As a minimum this is a two stage process which in general can take longer than the dry lining or dot and dab methods as the base coat must dry to a certain level before the finish coat can be applied. A base wet plaster can be obtained using many different methods, but the most commonly used are Bonding Coat, hardwall & sand and cement. A base coat plaster is usually 10 to 15mm thick, Ruled off and then floated over with a devil float and allowed to dry over night before the finishing coat can be applied, the skim coat is applied in two coats both of which is applied in 2mm thickness, the base coat is a coverage coat and the second is the finishing coat.
