Engineered hardwood floors can be glued or nailed into position, but they also have the option of being floated over an underlay.
Gluing hardwood floors includes pros like giving your floors a solid feel and sound as well as being least likely to have deflection between flooring and subflooring over nailing hardwood floors. One added bonus to this is you should not hear squeaking.
Nails allow for a more natural expansion and contraction of the hardwood floorboards with fewer problems. Because stapled floorboards are fastened tighter; the hardwoods may be more prone to cracking in response to changes in moisture because they cannot contract or expand as well as nailed floorboards.
Finish Nailer
If you're handy with a finish nail gun, you can use it to install a hardwood floor. A finish nail gun, designed for trim work, shoots a near-headless nail that does not mar the surface look of the wood, which makes a finish nailer effective for installing hardwood floors as well.
A brad nailer is one way to install engineered hardwood. Engineered hardwood is a solid wood floor product that is manufactured from thin layers of hardwood laminated together to provide planks with good durability and incredible dimensional consistency.
The two gauges of nails typically used for hardwood floors are 16- and 18-gauge.
Engineered hardwood flooring can resist warping from changes in temperature much better than solid hardwood flooring, so you only need to wait a day before walking on it.
Underlayment. You should always install engineered wood over an underlayment. Moisture barriers and underlayment prevent moisture build-up under your floors, keep your floors warm, reduce noise, and even out subfloor imperfections.
Staple-down installation is used for prefinished, engineered hardwood flooring on wood subfloors. This method uses a narrow crown stapler—which has a special nose that guides the staple through the tongue at the perfect angle—to fasten the flooring to wood subfloors.
The groove of the plank should face the wall and the tongue should face outward. This makes the tongue accessible for nailing, but not the groove.
Use 1-1/2" long cleat nails when installing thinner 1/2" thick wood flooring. Use 1-3/4" long cleat nails when installing 3/4" solid wood flooring, when 3/4" thick plywood is applied directly over a concrete slab—so the cleat nail does not go through the 3/4" thick plywood, hitting the concrete.
Staple/Nail Down
You must have a wood or plywood subfloor in order to staple or nail onto. Concrete or other hardboard type subfloor materials will not hold staples or nails. Staple/Nail down installation provides the best finished look as well, because the boards are “racked” together tight when hit with the nailer.
It makes them superior to solid hardwood floors in that aspect but do you still have to acclimate engineered hardwood flooring prior to installation? It is still recommended by manufacturers to acclimate engineered hardwood floors at least 48 hours or until they reach their acceptable moisture content.
Since laminate flooring is a floating floor, it is not meant to be attached to the subfloor by nails or glue. The floor needs to be able to expand and contract with temperature changes and therefore must freely lay on the underlayment or subfloor.
Engineered hardwood typically lasts between 20 and 30 years. Because they do have a top layer of hardwood, like solid hardwood, they are susceptible to scratches. If scratch resistance is important to you, look for engineered hardwood floors with a scratch-resistant top coat.
If your hardwood floors have been sanded and finished with Bona Mega Clear HD, it is safe to sleep in the home about 2-3 hours after the project is finished, but again, only if there are other rooms that have not been robbed of their furniture – furniture should stay off floors for at least 24 hours after ANY project ...
All traditional engineered hardwood is not waterproof. A new engineered hardwood product has a vinyl core with a wooden top or outer wooden layer. It is called engineered vinyl plank or EVP.
Scratches, Dents and Other Small Marks
Due to the fact that engineered flooring has a top layer of solid wood it is actually susceptible to the same drawbacks of having solid hardwood floors such as easily being scratched and dented.
Con: Maintenance
Hardwood flooring of any kind will take quite a lot of maintenance to keep its shine and lustre. Engineered wood is no different in this respect, therefore not particularly suitable to home's with pets or young children unless you are prepared to keep up with regular maintenance.
If you have solid hardwood or engineered wood floorboards, the creak might be caused by the floorboards rubbing against each other. Squirt powdered graphite between the boards, then lightly rub the product into the seams with a soft brush or cloth.
Solid hardwood floors must be fixed into position by either gluing or nailing down to the subfloor. Engineered hardwood floors can be glued or nailed into position, but they also have the option of being floated over an underlay.
The 8D or 8-penny size finishing nail is common for the job of flooring. Predrilling nail holes avoids split boards. Additionally, a nail-set tool lets you tap the nail head into the board without the risk of denting it with the hammer.
Brad nails, or brads, are made of 18-gauge steel wire. Nail gauge sizes indicate the thickness of the nail. Thinner nails have higher gauge numbers. The small diameter of brad nails makes them easy to mask in wood trim or paneling. In addition to being thinner than standard nails, they also feature a smaller head.
