Q: Should I use an adhesive remover to remove adhesive residue from a subfloor before installing a new floor? |
| |
|
A: Many adhesive removal products contain solvents that leave a residue within the subfloor. This residue can negatively affect the new adhesive and bleed through the new floor covering. Floor covering warranties do not cover instances where existing subfloor conditions cause damage to the flooring or installation failure. |

Q: Can I install an ZAXXON floor on a radiant-heated substrate? |
| |
|
A: ZAXXON flooring may be installed over radiant-heated subfloors as long as the surface temperature does not exceed 85˘XF (29˘XC). Temperatures above 85˘XF (29˘XC) will cause the flooring to soften and increase the risk of irreversible indentation. |

Q: Why does ZAXXON recommend not smoothing true expansion joints with any type of underlayment product? |
| |
|
A: True expansion joints are those placed between separate pours of concrete. These joints are designed to absorb the movement of the concrete and are normally filled with elastomeric fillers which absorb the movement of the separate pieces of concrete. If an underlayment is placed across or in these joints, the movement of the concrete will cause them to break up or will push them out of the joint. Additionally, any flooring placed across these joints will break with the movement of the concrete. Expansion joint covers, which are designed to span these joints, should be used in these areas. |

Q: Why can't you install flooring directly over paint or other coatings on a subfloor? |
| |
|
A: The bond of the flooring to the subfloor is only as good as what you bond to. If you bond to old paint, sealers, polish, or other foreign matter, you are dependent upon the bond of that material to the subfloor to hold the flooring in place. Since we cannot determine how strong that bond may be, it is best to bond directly to the substrate. |

Q: What is a sleeper-constructed subfloor and why can't I install flooring over this? |
| |
|
A: This is a wood subfloor installed over an existing concrete subfloor without 18" of well ventilated air space below. Concrete on or below grade will have some moisture in it due to its proximity to the ground. When there is not enough ventilation, moisture will build up causing not only installation failure, but possible rotting of the wood. Suspended grade subfloors that are not sufficiently dry can experience the the same problems. |

Q: Why should new tile not be installed over existing tile that is below grade? |
| |
|
A: Tile over tile is not recommended on a floor below grade. A basement is below grade and concrete below grade will almost always have moisture in it. A single layer of tile allows any moisture in the concrete to escape through tile joints. When you place new tile over existing tile, you cover the tile joints and cut off the escape route for the moisture. This traps the moisture beneath the tile and can cause loosening of the old tile as well as the new tile. |

Q: What board underlayment products should I put in place before installing resilient floor products? |
| |
|
A: Underlayments for resilient floors should be structurally sound and designed for resilient flooring underlayment purposes, with a minimum thickness of 1/4". The panels should be smooth enough so that the texture or graining will not show through the finished flooring. They should also resist dents and punctures from concentrated loads. The panels should not contain any substance that may stain vinyl such as edge patching compounds, marking inks, paints, solvents, adhesives, asphalt, dye, etc. Check with your supplier or panel manufacturer. Install the underlayment in strict accordance with the board manufacturer's recommendations. |
