Vinyl Flooring A little experience I wanna share. If you are installing vinyl and laminate flooring, you may want to consider to do a clean up before installation. Think about it, all the hacking, patching, painting etc bound to have a little debris, nitty little pieces here and there. These little pieces will affect the overall finish of the flooring. If the small pieces are not removed, it may not show immediately. This is because vinyl and laminate has a layer of rubber or foam as the under layer. It is over time and adding on of weight on the flooring then the little lump will be more obvious. By this time, you may have move in 3-6 months already. Such issue can be rectify easily but the process is tedious and may face restrictions. With vinyl, you will have to remove from the edge of the wall that is nearest to the defect area. Despite being clip on system, vinyl are not exactly built and meant for remove/refit again. During removing, the edges may flare or buff and result in more defects. Also sometimes the nearest wall has a carpentry sitting on it and restrict access. Prior to installation, no doubt the flooring guys will clean up these are restricted to only sweeping. And it is done area by area ie. they clean the area they are installing and so on. What I had done requires a little more effort and time. I cleaned up the whole house to the best I could. First by sweeping then by vacuuming and finally mopping. It is a tedious and tiring process but it yields good result. Please use a vacuum that is not using a dust bag. Easier to dispose but be prepare for rough usage. Of course not every one have the time or the effort to do it this way but on one hand it facilitates the flooring guys to do a quicker and better job, on the other they know you meant business and will try harder to do a better job. Anyway, I was there for the whole installation process which took about 3 x 1 day session due to timing and the leveling of the balcony area. A point to note, please stop them from working late when there are no lighting in the unit for no one can see if each vinyl/laminate are in good condition.
