Question
Any suggestions for affixing a stainless steel bar top to a plywood substrate? We tried silicone and didn't have much luck.

PL and Sikaflex make a similar product that is sold at Home Depot. They are both very good as well, but nothing beats 5200.

From contributor K:
Surprised nobody has mentioned good old construction adhesive. Done this quite a few times using PL400 with good results.

From contributor I:
I would like to glue copper sheet to a gluable backer (melamine on particleboard). I've gotten different opinions from suppliers. Any ideas?

From contributor O:
PL construction adhesives will glue virtually anything to anything and I have had some interesting accidental glue-ups to prove it.

From contributor U:
I have a client who wants to completely cover a lot of hollow metal door and window frames with hardwood trim to achieve a more traditional appearance. What would be the best adhesive assuming I don't want to use mechanical fasteners that would have to be countersunk and plugged?

From Jeff Pitcher, forum technical advisor:
Assuming they can clamp it, I'd suggest a reactive PUR.

Polyurethane is one of the best materials to use for sealing the exterior of your home. This exterior caulk is UV resistant, so you won’t have to look at ugly yellowing over time on what was a clear bead of caulking. Exterior polyurethane caulk also has similar flexibility to silicone, allowing it to absorb impact damage or expand and contract with ambient temperatures.

Polyurethane caulk can be painted, allowing you to give your home the flawless aesthetic you desire. And it is great for sealing together different types of materials, such as metal and wood or wood and glass. However, it is very thick and potentially difficult to work with if you don’t have experience with a caulking gun. It’s also one of the more expensive exterior caulk types.

Latex and acrylic latex are the least durable exterior caulks because, once cured, they don’t have the ability to expand and contract. This rigidity causes them to break down much sooner than silicone, polyurethane, or butyl rubber exterior caulk. Silicone has better water resistance than polyurethane but doesn’t adhere well to wood, while polyurethane works with most materials, even forming effective seals between two different materials.

Some areas around your home may go untouched by anyone for years, but they are still exposed to powerful wind, rain, hail, and possibly snow. For this reason, you need to ensure that you are investing in a product with the durability necessary for the application area. [links]

Use this caulk for filling small gaps and blemishes in wood trim and for sealing joints between wood parts that will be painted. While the label may claim it's suitable for wet areas, it's best to stick to dry areas or on parts with may see moisture (like exterior trim and siding) but will be protected by a complete coating of paint.

Silicone will work on roofs and windows or doors, but it's not the best option for those applications. Instead, use a high-quality roofing sealant for roof work, and use a high-quality window and door sealant (not latex caulk) for installing and sealing windows and doors (it lasts as long as silicone and is paintable).

Your project calls for caulk, but you can picture yourself at the home store facing a towering wall of caulk tubes that all look alike. We've all been there. The good news is, there's a right caulk for the job; you just have to look through the weeds and, sometimes, misleading labels to find what you need. This overview of the main types of caulk will help.

Use pure silicone for sealing around plumbing fixtures, such as sinks, toilets, and faucets, and for any caulk joints on the tile in wet areas. It's also a general-purpose sealant and waterproofer for things like holes in exterior walls, sealing around pipe and wiring penetrations, and filling gaps between exposed materials of almost any type. Finally, pure silicone is a pretty strong adhesive and can be used as a glue for things like undermount sinks or fixtures attached to stone and other hard-to-glue materials. [links]

A good tube of silicone sealer is an excellent tool to have on hand for cracks that come about from heat exposure, wear, and tear moisture or chemical use.

Does your skylight gasket in the RV have a few cracks and tears? Are you tired of getting wet while you are trying to enjoy a nice campfire meal? Tired of the whistling around the cracked weatherstripping in your Camaro? The Permatex Clear RTV might be exactly what you are looking for the clear caulking. It can fill up the holes and create a waterproof seal that lasts.
