Q:We recently bought a house with a corner tub in the master bathroom. There was a partially covered pipe for a shower head but the walls are not waterproof. Since the plumbing is there for a shower we would like to waterproof the walls and put in a shower head. Is there a chance the builder put up cement board but skipped tiling? Is there a way to tell without ripping the walls down? Also I'm wondering if we need to tear down the existing drywall and put up cement board or if we can just use a type of acrylic shower wall and caulk it really well. Any advice would be appreciated.

Q:weather stripping/ foam strip?

Those foam strips they sell you to go under the ridge caps will eventually dry out, blow out, and be hanging all over the place. Caulking won't fill a 5/8's gap to keep the wind/rain out, and tar has no place whatsoever on a metal roof, you'll get it all over everything, and either one will look like ****. The best ridge cap has to be custom made and cut to fit. I use a 12" wide X 10' strip, bent in half to pitch, and then turn down 90 degrees on the edges, whatever the rib height is, usually 5/8". Hold the ridge cap in place on the ridge and mark where the ribs are, then notch out for the ribs so that the cap sits flush over the ribs and down on the flats, punch holes and screw down thru the tops of the ribs. It's a little time consuming but it makes for a good looking finished product that won't wear out.

Q:How does steel formwork handle different concrete jointing techniques?

Steel formwork is a versatile and sturdy system that effortlessly handles diverse concrete jointing techniques. Whether employing traditional or modern methods, steel formwork offers the necessary structural support and adaptability to meet various jointing requirements. For traditional jointing techniques like construction or control joints, steel formwork facilitates precise and clean concrete cuts. Acting as a guide, the formwork ensures accurate joint placement and alignment. The rigid structure of the steel formwork guarantees stability during the pouring process, preventing any misalignment or movement that could impact the jointing. In the case of modern jointing techniques, such as expansion joints, steel formwork can be adjusted to accommodate desired joint spacing and movement. Additional features, like flexible connections or removable sections, can be incorporated into the formwork design. This allows for the necessary expansion or contraction of the concrete, ensuring the joints remain intact and functional even in the face of temperature or moisture-related changes. Moreover, steel formwork offers the advantage of reusable panels and components. This means that the formwork can be easily disassembled and reassembled to suit different jointing techniques or even used for future projects. This flexibility and versatility make steel formwork a cost-effective and efficient choice for managing various concrete jointing techniques. In conclusion, steel formwork is well-suited to handle a range of concrete jointing techniques. Its strength, stability, and adjustability enable precise and accurate joint placement, while its reusability makes it a practical option for diverse projects.

Q:What is aluminum plastic material?

Aluminum-plastic composite board is a chemically treated coated aluminum sheet for the surface material, with polyethylene plastic as the core material, in the special aluminum-plastic plate production equipment from the processing of composite materials. The unique performance of the aluminum-plastic composite panel itself determines its wide range of uses: it can be used for building facades, curtain wall panels, retrofits of old buildings, interior walls and ceilings, advertising signs, display stands, engineering.

Q:Is steel formwork suitable for projects with heavy concrete loads?

Yes, steel formwork is highly suitable for projects with heavy concrete loads. Steel formwork is known for its strength, durability, and load-bearing capacity, making it ideal for projects that involve heavy concrete loads. Steel formwork can withstand the pressure and weight of the concrete, ensuring that it maintains its shape and integrity throughout the pouring and curing process. Additionally, steel formwork offers excellent dimensional accuracy, allowing for precise and consistent concrete placement, which is crucial for projects with heavy loads. Overall, steel formwork is a reliable and robust choice for projects that require the support of heavy concrete loads.

Q:Plastic window around the gap with cement plug or foam plug?

For the gap between the box and the wall of the filler and surface treatment requirements in the "Building Decoration Construction Quality Acceptance Specification (GB-2001)" Article 5.4.7 states: "Plastic door frame and the gap between the wall should be used Closed hole elastic material filled full, the surface should be sealed with sealant sealant should be bonded firmly, the surface should be smooth and smooth, no cracks. 2. According to "plastic doors and windows installation and acceptance procedures (JGJ103-96)" Article 4.2.11.2 provides: insulation, sound insulation window, the hole between the inside and the window frame should be used to fill the cement mortar smooth; when the plaster , The sheet should be used to temporarily remove the plaster layer and the window frame, the thickness should be 5mm, plaster surface should be beyond the window frame, the thickness of the fan does not affect the opening is limited (see " Node graph). To be outside the plaster layer hardened, should remove the sheet, and the caulking paste into the plaster layer and window frame gap. Insulation, sound insulation requirements of the higher project, between the inside of the hole and the window frame should also be used to seal the seal. 3. Also in the "plastic doors and windows installation and acceptance procedures (JGJ103-96)" Article 4.2.10 of the provisions of the filler more detailed: window frame and the hole between the expansion joints should be used in closed cavity foam, Foam polystyrene and other elastic materials layered packing, packing should not be too tight. For insulation, insulation requirements of the higher level of the project should be the use of the corresponding insulation, sound insulation material stuffing.

Q:How to remove the floor tile rust

Rust the main component of ferric oxide, was dumb red, tiles once stained, very stubborn, with the general cleaning method can not remove it. To clear it, ask for acidic substances to help. As a result of the ridicule cans and intestines, the dirt caused by the construction of the dirt are used in the general chemical shops have sold, oxalic acid is weak, not a dangerous goods, buy Unrestricted can clean the tiles, porcelain above the oil, paint, tea, etc., but the effect is not hydrochloric acid is good, hydrochloric acid should be used to dilute it, so as not to cause damage to the body, it is dangerous goods, the purchase also has a certain limit, Wash with oxalic acid. Oxalic acid on the tile surface is not damaged. And the general chemical pharmacy is easy to buy. Second, dilute hydrochloric acid or dilute sulfuric acid: such substances are dangerous goods. Chemical pharmacies are generally not easy to sell, even if the sale will be strictly controlled. Such substances due to acidity is too strong, likely to cause damage to the tile surface. Third, other acidic substances.

Q:What are asbestos and what are their health ramifications?

From the first reference: Asbestos is a mineral fiber that has been used commonly in a variety of building construction materials for insulation and as a fire-retardant. Because of its fiber strength and heat resistant properties, asbestos has been used for a wide range of manufactured goods, mostly in building materials (roofing shingles, ceiling and floor tiles, paper products, and asbestos cement products), friction products (automobile clutch, brake, and transmission parts), heat-resistant fabrics, packaging, gaskets, and coatings. When asbestos-containing materials are damaged or disturbed by repair, remodeling or demolition activities, microscopic fibers become airborne and can be inhaled into the lungs, where they can cause significant health problems. There are many websites on the subject that a simple search will find. There are also many than have agendas, so be careful.
