Learn how to perform an engineered wood floor repair. Does your glue down flooring have a bounce or hollow space underneath? Loose engineered hardwood flooring? Make the necessary hardwood floor repair, before it becomes a bigger problem.
The main causes for this problem - sub-floor not flat to tolerance, poor quality wood floor mastic or flooring mastic setting up too soon and not bonding to the wooden flooring, sub-floor was not primed with glue primer.
Fix these problems right away and avoid the domino effect it can create. Here's how to perform an engineered hardwood floor repair.
Determine how big of an area, that needs to repair, by knocking on the wood flooring. Listen to the distinct sound of a hollow knock. Keep knocking until you find a solid thump. Place blue tape at this point. Continue knocking until you have determined the outer boards of the floor repair are. And have the perimeters of the repair taped off.
Locate the center of the problem area. And remove the piece at the center. There are a couple of different methods on how to remove the first boards. This would depend on what type of tooling you have access to.
First method: Circular saw and multi-tool
This is the fastest method to remove the first board. Start by using the circular saw set at the proper flooring thickness. Cut along the joint line of the board you will be removing. And then remove the board, By using a thin pry-bar or flat screw driver. The piece should easily pop up. If, it doesn't re-cut the area. Sometime it is necessary to cut more than one board, depending on the layout of the flooring. You then should be able to start removing all the loose boards from your problem area.
Second Method: Hammer and chisel
Using a sharp 1/2 chisel, chisel a channel, carefully, down the middle of your wood flooring strip. Then chisel each layer off, de-laminating the engineered flooring strip. You will then be able to remove the following loose engineered flooring boards without causing other adjacent boards to become loose, preventing a domino effect.
Remove any old adhesive and wood chips by scraping and cleaning, from the surface of the sub-floor and under any tongue and groove area of your glue down flooring. If, you have an excessive dip in your sub floor. Perform a sub-floor repair, by using a skim coat compound application, to fill in the low spot. Before you continue with your engineered floor repair.
Using a pry bar to lift the wood floorings that are still in tack, about 1/4" up. Apply sub-floor polyurethane glue (liquid nail) under the flooring and in the floor repair area. You can then begin to install your new replacement flooring boards
Apply weights to the wood floor repair section. Use books, paint cans, weights, tool box, etc. Use anything that will help keep pressure on top of the floor repair area.
Check to see if, your engineered hardwood flooring is sitting tight to your sub-floor by simply giving it a knock. You should hear a solid knock, apply more weight, if, you hear a hollow knock.
Allow the adhesive on your floor repair to dry for 24 hours, before removing your weights. And moving your furnitures back.
