There are a wide variety of different
adhesives you could
use to build a stairway. Knowing which ones actually work and which ones
don't, could make all of the difference in the world, especially if you
don't want to have any problems in the future.
Stair Framing AdhesivesIn the middle of the picture above, there's a polyurethane premium construction adhesive that usually says for doors and windows, on the container. It is one of the best products you could possibly use for gluing your stair treads and risers to the stringers.
Now is when you're probably wondering, why would I care, whether or not my stair treads are glued, to the stringers. Well, if you're not worried about your stairs squeaking in the future, I wouldn't worry about gluing them, either. However, simply by applying the right construction adhesive, you could end up with a nice set of stairs that isn't noisy.
Regular construction adhesive without the polyurethane, seem to get brittle and doesn't have the holding power, especially once the stair stringers start to dry out and shrink.
Carpenters GlueThey have more varieties of Carpenters glue today, than ever before. Some of the premium wood glues available today have incredible holding power. It's hard to suggest just one single product, over the other ones, because most of them work great.
To be honest with you, I've used almost every glue imaginable and haven't ever had one problem with either one of these products.
Indoor And Outdoor AdhesivesIf you're planning on building a project for the exterior of your home, make sure that you find a glue that has an exterior rating. These clues will be able to withstand some of the temperature and moisture fluctuations, a little better than regular glue.
Most exterior adhesives can be used on the interior of your home, but you should always verify with the manufacturer, before using it. Some indoor glues produce toxic fumes that could be dangerous if used inside of the building.
