Getting off to a clean start with PlaniprepTM Surface Preparation products
Getting off to a clean start Planiprep™ Surface Preparation products ensure a suitable surface for new floor-covering installations

proBleM: a very Messy FloorInG FaIlure
What if this happened at your school? A previous resilient floor-covering installation has failed due to high moisture emission coming through the concrete subfloor. Moisture testing results show moisture vapour emission rates (MVERs) averaging somewhere between 10 to 12 pounds per 1,000 square feet (4,54-5,44 kg per 92,9 m2) per 24 hours. Relative humidity testing of the concrete slab also indicates the slab is still damp, with readings between 90 to 95 per cent.
It is necessary to remove the existing resilient material and successfully replace it with new vinyl flooring. Shotblasting is not a viable option for surface preparation due to noise, cost and dust containment issues, but the subfloor must be “clean” and free from any contaminants that might affect the new floor installation.
solutIon: GettInG to a clean Base
Virtually all flooring manufacturers require a concrete subfloor to be free from any dirt, debris, adhesive residues, curing or parting agents, and other contaminants that may interfere with the bond of any given installation method. On virtually all replacement flooring installation projects, some form of contaminant remains on the subfloor.
Planiprep Surface Preparation Products offers a three-step process for adhesive removal, concrete cleaning and capping of the subfloor prior to installing new flooring. 1. Planiprep AR is the first step in preparing a concrete subfloor to receive new floor covering. This adhesive remover is a powerful, waterbased adhesive remover designed to remove most latex-based adhesives quickly and easily from the surface of concrete subfloors, replacing the need for shot-blasting. 2. Planiprep SA is a powerful, water-based stripping solution that

lifts out many common concrete contaminants such as oils, postabatement chemicals and adhesive removers, such as Planiprep AR adhesive remover. This product will chemically etch the surface of clean concrete, thus promoting excellent adhesion for the subsequent application of Planiprep ET. 3. Planiprep ET epoxy concrete subfloor treatment is an ultra-low-viscosity, two-component, penetrating, 100-per-cent-epoxy treatment designed to be used as part of the system with Planiprep SA concrete scouring agent. This product system provides subfloor moisture emission control up to 12 pounds (5,44 kg) and 90 per cent relative humidity (RH).
After using Planiprep Surface Preparation Products to remove the old adhesive, clean the concrete and cap it to prevent further moisture intrusion, the new floor covering can be put in place. Installers can bond directly to Planiprep ET using reactive and/or pressure-sensitive type adhesives; or they can treat the Planiprep ET with a primer suitable for use over epoxy membranes, and then either skim-coat with patching compounds or apply a self-leveling underlayment to provide a perfect surface for the new floor covering.
Planiprep Surface Preparation Products (SPP) produce great results while providing a quality environment, whether for students in schools or patients in hospitals. The products are low-odour and VOC-compliant for use in interior, occupied environments. When dust and noise present a problem, the Planiprep SPP system successfully addresses the issue. MAPEI works continuously to provide technology on which you can build.
