Drywall construction – no problem with the right equipment

Drywalling has been all the rage over the last few years: drywalls have become a familiar sight among architects, planning agencies, interior fitters, carpenters, painters, plasterers and plumbers. The first drywalls were used primarily in commercial applications and were comprised of sections of plasterboard that were joined together. Nowadays, requirements in the commercial and private construction sectors are extremely complex and many different types of dry, lightweight interior fitting are available. This development has had a wider influence on all areas of the construction industry: composite materials, panel heating and cooling systems (integrated in drywalls), highly soundproof ceiling, wall and floor systems that incorporate wood/glass/stainless steel and aluminium coated panel materials, conductive and photoactive plasterboard with a large storage capacity are some of the many areas developing in the drywalling industry. Potential for technical and creative innovation is given limitless freedom as a consequence. However, these developments also reveal that conditions for protecting the environment and saving resources will improve in the future. What implications do these developments have for traders? How will the trend develop, how can traders adapt, where can they procure the relevant information and how can they prepare themselves for changing materials?

Cutting and rebating panels efficiently

As a general rule, painters usually set up a stand before starting drywalling work. The painter can drill dowel holes for attaching the stand element quickly and efficiently using the Protool impact hammer CHP 26. Once the stands are set up, the painter can start rebating: many plasterboard manufacturers offer prefabricated profiled parts. Festool manufactures hand-guided electric power tools that offer painters the possibility of machining profiled parts, in particular in manual applications. Machines such as the TS 55 plunge-cut saw and the OF 1010 router are perfect for assembly tasks because they are lightweight and easy to use and their investment costs are lower. Panels that are unsuitable for cutting blades can be cut to length using the TS 55 plunge-cut saw with depth adjuster. A 45° or 90° corner can be rebated into panels using the OF 1010 router, guide system and a suitable plasterboard cutter. The fine adjuster enables painters to route more accurately in the workshop and perform precision tasks at the customer’s premises to prevent time-consuming rework.

Precise, secure fastening in drywalls

When inserting screws in drywalls, the painter requires a cordless drill that provides sufficient power and is fitted with a precision adjuster for the screw insertion depth. T+3 cordless drills from Festool incorporate impressive features such as outstanding power and an excellent fastening capacity per battery charge combined with a low weight. The T+3 series does not operate in the classic volt categories of 12 and 15 V, but generates additional power with the EC-TEC motor concept. Together with intelligent high-performance electronics and modern lithium-ion technology, the machines from the T+3 series not only operate relentlessly but even reach performance levels that are usually only to be found in the next highest voltage class. An accurate screw insertion depth setting is extremely important in order to avoid uneven surfaces and prevent inserting screws too deep, particularly when securing planks to drywalls. Festool has developed a depth stop specially designed for drywall applications that allows drywallers, painters, plasterers and interior fitters to achieve precision insertion depths time and again. The depth stop has an integral claw coupling, which maintains the preset fastening depth. The unique correction function enables quick and easy removal of screws inserted at an angle. A detachable stop sleeve is fitted to the end of the depth stop for quick bit changes. The depth stop is available as an accessory for all Festool drivers with FastFix chuck or for the C12 DUO.

Maximum power when inserting screws in professional drywall applications

The new DuraDrive DWC 12-4000 DEC Li drywaller screwdriver from Protool was developed for continual use in professional drywall applications. The specially developed machine operates at the perfect speed for drywall applications and allows the user to secure gypsum plasterboard to the base frame structure precisely and with minimum effort. Due to an ergonomic shape and design, the 1.7 kg DuraDrive rests snugly in the hand and is perfect for inserting loose screws or strips of screws with a magazine attachment. The machine can fasten 975 screws per battery charge, which means the DuraDrive can secure an average of 25 gypsum plasterboards per battery charge.

The staying power of the tool can be attributed to features such as the electronic cut-out, li-ion battery technology, EC-TEC motor and an innovative start/stop function, and is far greater than any of its competitors. The function ensures that the motor only starts when a screw is inserted. The user can even activate AUTO mode to perform this task automatically without pressing the main switch. Simply position the screw and apply pressure to insert. Pressing a trigger continuously is now a thing of the past. During continuous use, the DuraDrive simplifies the work of drywall professionals considerably while simultaneously providing a customised solution for the precision insertion of large numbers of screws within a very short time.

Bonding and stapling plasterboard     

Plasterboard is easy to bond using the KTP 310 Alu applicator gun from Schneider. The stepless speed control allows extremely delicate material dosage. The applicator gun also has a rotary cartridge holder that prevents the user from having to put down tool to change the application direction and a quick-release valve ensures that material does not continue to escape when the trigger is released. The compact design and low weight of the applicator gun guarantee non-tiring work, even over longer periods. Commercial plastic and aluminium cartridges or pouches can be inserted in the gun, which is quick and easy to clean due to the smooth surfaces on the interior and exterior. (Technical data: air requirements 100 l/min., working pressure 8 bar, weight 0.98 kg). The new KLG 114-65 stapler from Schneider with precision staple insertion depth setting is suitable for securing plasterboard (special Fermacell), OSB panels and chip board as well as for manufacturing boxes, pallets, crates, frames and shuttering. The user can adjust the trigger setting to single or contact release. The adjustable exhaust air guide can be aligned to the best position for the user and workpiece. (Technical data: working pressure 5-8 bar, air requirements 1.3 l/impact, weight 2.5 kg, magazine capacity 130 staples, staple type 114 between 32-65 mm in length)

Large surface sanding

When preparing a surface prior to wallpapering or painting, the entire surface must be sanded from top to bottom. Sanding off walls and ceilings in high rooms could be so easy if scaffolding were used. However, scaffolding is not always practical and even sanding on ladders is a difficult task. The solution here is the PLANEX LHS 225 long-reach sander, which can be adapted to match the height of the ceiling. After filling gaps and screw holes, initial surface sanding is performed at medium speed using the combined long/short-reach sander and a fine sandpaper because the sander is extremely powerful. For a perfect finish the surface should then be sanded right up to the edges and into the corners using a sandpaper with P180 grit. The SRM 45 E mobile dust extractor operating in the background causes the machine to adhere slightly to the surface, ensuring quick, effortless machine guidance. The combination of the PLANEX LHS 225 and SRM 45 E special extractor enables painters to prepare walls and ceilings quickly, efficiently and with minimum effort without requiring scaffolding or a ladder. Painters can also achieve extremely efficient material removal rates on drywalls using the Cristal and Brilliant sandpaper grades in grits P40 to P320.

Painters can finish work on drywalls quickly, efficiently and effectively with the help of the right equipment. The correct selection of dust extractor, electric power tool, sanding pad, abrasive, saw blade and accessories will prepare painters well for any further developments in the drywalling sector.
