Step 2: Floor surface preparation
Remove all nails that are protruding above the surface of the flooring, and with a nail punch and hammer punch each floor fixing nail below the surface of the floor 3-4mm.
In rare instances vinyl is laid direct to the flooring with an adhesive, this is very hard to remove and some research will need to be carried out to find a suitable solvent to break down the glue. Otherwise good old elbow grease with a lot of patience and persistence is the answer, sanding generally does not work on the glue as it only melts and clogs up the paper.
Squeaks and loose boards can be re-nailed down into the floor frame with 50mm bullet head nails. If this proves unsuccessful you will need to access under the floor. Locate over which floor joist the problem is and how long the loose area is along the floor joist. Cut a piece of 42mm x I9mm pine 300mm longer than the area under which the problem is, apply a thick and generous bead of liquid nails to the junction of the joist and flooring and to the flooring and side of the joist (Fig. 2). Press the 42mm x I9mm pine firmly into position ensuring that there is an excess of adhesive to both surfaces. Hold the timber firmly against both surfaces and nail the 42mm x I9mm pine to the floor joist with the 50mm nails at 300mm spacings. Allow the adhesive a day or two to set before commencing any sanding.
Clear all furniture, furnishings and pictures out of the room to be sanded and thoroughly clean the floor, a vacuum is best for this. And either remove items from built-in furniture or protect them by covering and sealing them with drop sheets and duct tape.
