Does SnapStone® tile require an acclimation period before installation?
SnapStone porcelain tile is a very stable, and does not require acclimation if installed under normal climate conditions of 65-80°F. If, however, the temperature variance is greater than 20°F from storage to jobsite, a 24 hour acclimation period is recommended.
Does SnapStone® require an underlayment?
No. The rubberized grid on the back of the tray eliminates the need for an underlayment.
How thick must the sub-floor be in order to install the SnapStone tile?
5/8" installed over 16" on center.
How flat does a sub-floor need to be in order to install SnapStone tile?
For tile with all edges shorter than 15", maximum allowable variation is 1/4" in 10' from the required plane, with no more than 1/16" variation in 12" when measured from the high points in the surface. For tiles with at least one edge 15" in length, maximum allowable variation is 1/8" in 10' from the required plane, with no more than 1/16" variation in 24" when measured from the high points in the surface, as indicated by the Tile Council of North America (TCNA) Handbook.
Over what type of sub-floors can SnapStone tile be installed?
SnapStone can be installed on permanent, solid surfaces. This includes vinyl, plywood, OSB, particle
board, concrete, and ceramic that meet the TCNA Handbook's requirements for subfloors/substrates. Avoid non-solid, uneven surfaces such as carpet. SnapStone should not be installed over other floating floor systems, such as laminate wood floors.
What do I do if there is a dip in the middle of the sub-floor?
Use a straight edge to determine the depth of the low spot. If it exceeds the tolerance requirement for the tile size, as required by the Tile Council of North America (TCNA) Handbook for Ceramic Tile Installation, then it will need to be filled. Cement based patching compounds works best. Avoid gypsum patching compounds in wet areas since they may support mold growth.
What do I do if there is a high spot in the middle of my floor?
If the high spot exceeds the tolerance requirement for the tile size, as required by the Tile Council of North America (TCNA) Handbook for Ceramic Tile Installation, then it will need to be removed. First, determine how much of the high spot needs to be removed. High spots can be sanded with a belt sander or edger; or, by using a planer. Remember: never sand existing resilient floor covering as it may contain asbestos. Removing high spots may require inspection from a carpenter to ensure the floor remains structurally sound. Please note:Operate all equipment according to the manufacturers' instructions and safety requirements.
Can SnapStone tile be installed over a crack in the sub-floor?
Yes. Unlike a traditionally installed ceramic tile floor, SnapStone porcelain tile can be installed over cracks and expansion joints in concrete as long as the crack does not cause a height difference in the floor.
My floor squeaks. Should I fix it before I install SnapStone tile?
If the floor squeaks now, it will squeak after SnapStone tile is installed. Please consult a carpenter
if you wish to address the squeaking floor.
My previous floor left an adhesive residue on the sub-floor. Can I install SnapStone tile
directly over this surface?
If the old adhesive residue is completely dry, then yes. However, if the residue is sticky, it is recommended to first install a thin underlayment (1/8") over the floor. This will provide a smooth surface for installing your floor.
Is there an alternative to leveling the floor with a patching compound?
Yes. Using 1/8" hardboard is an alternative to leveling the floor with patching compound. It may be a little more expensive, but could be a good option if you do not have experience patching floors.
Do I need to remove my vinyl floor before installing the SnapStone flooring system?
No. the SnapStone Floating Porcelain Tile System can be installed directly over your existing vinyl floor as long as the joist and subfloor/substrate requirements from the TCNA(Tile Council of North America) Handbook
for Ceramic Tile Installation are met.
I have baseboards and quarter round on my walls. Should I remove them before installing SnapStone?
Yes. The quarter round or base shoe should be removed, and then re-installed to cover the expansion gaps along the perimeter. It is not necessary to remove the baseboards.
Do I need to remove my old flooring before I install my SnapStone floor?
Not all the existing floors need to be removed. The SnapStone system can be installed over most clean, dry, structurally sound floors such as vinyl, wood, concrete, or ceramic. It should not be installed over carpet, as long as it meets the joist and subfloor/substrate requirments as defined
by the TCNA Handbook for Ceramic Tile Installation.
My old vinyl tile floor is missing a few pieces. Do I have to remove the whole floor to install SnapStone?
No. If the vinyl tile is well bonded to its sub-floor and only a few pieces are missing, just use cement based patching compound to fill the missing areas. Then, once the floor is flat according to the requirements of the TCNA Handbook for Ceramic Tile Installation, SnapStone can be installed. Use caution when removing loose tile as some vinyl tiles may contain asbestos.
Do I need to remove the paint from the concrete floor before installing SnapStone tile?
My third floor condo has lightweight concrete, and I'm told that primers and sealers need to be applied before my tile floor can be installed. Is this necessary with SnapStone?
No, as long as the floor is within a tolerance of ¼" in 10' and 1/16" in 1'; according to the TCNA Handbook for Ceramic Tile Installation.
Are there any deflection requirements for SnapStone tile?
The floor must not have deflection greater than 1/360 of the span when measured under a 300 lb concentrated load (See ASTM C 627).
Do I need to undercut the door jambs and casings?
No, it is not required. However, you will still need to allow ¼" expansion at the jambs. Undercutting of the jambs is used to cover the cut edges while still providing this needed expansion.
What is the best way to undercut the door jambs and casings?
If there are only a few door jambs and casings to cut, it is easiest to use a sharp hand saw. A scrap piece of SnapStone tile can be used as a guide to ensure the casing is cut at the exact height needed. If there is a large number of door jambs and casings, a power jamb saw is recommended. (NOTE: Follow the manufacturers' instructions and safety requirments when operating tools and machinery.)
