Probably not. Laying a floor properly is only one part of the equation, breaking in your floor correctly is as important and this is most often why floors creak (mine included!). The correct procedure for breaking a wood floor regardless of the type of subfloor is to set your heating at ambient temperature and raise it by 1 degree per day until the room is at the correct temperature. Not following this procedure will contract the floor and within a few months, your floor will creak underfoot.
Most modern engineered wood and laminate floors use a click system that locks the planks together a bit like a giant jigsaw puzzle. Stop Creak is specifically designed for these floors. For Stop Creak to work it must be able to penetrate in-between the planks so it works best of click system floors that have a V-Groove/visible groove between planks.
Stop Creak probably won't work for your floor because it needs to get to the area of friction that is creating the creaking.
It depends on the size of your rooms and how creaky they are. Stop Creak is applied by spraying into the grooves between the planks. It works in seconds and you can silence an entire room in about 10 minutes.
Stop Creak lasts for 2 years+ however, most customers apply Stop Creak to the areas of the floor that creaks and then keep a can handy to treat other areas of the floor that might start creaking in future.
Not necessarily. Your creaking may be coming from the subfloor in which case you can either pull up the floor and spray the underneath with Stop Creak (we have several customers who have used Stop Creak with success in this way) or you need to have your underlay and joists inspected by a flooring expert.
Stop Creak is the cheapest way to fix a creaky floor. The other alternative is to replace you floor which will cost many thousands of pounds. However, Stop Creak might not work on your floor simply because you may have more serious issues causing the creaks that Stop Creak can't help with. If you bike creaks after you oil it, do you send back the lubricant you used or take your bike to a bike shop to figure out what the problem is? Stop Creak works the same way. It's a floor lubricant that works fantastically well when it's used for dried out, contracted floors. It definitely won't fix your subfloor, your joists or anything else that is structurally wrong with your floor.
No. Most traditional floorboards are nailed down and so the creaking is usually down to the wood sliding up and down the nail when under load. We don't recommend Stop Creak for these floors.
Unlikely and not recommended.
