Topically Applied Slab Densifiers

Spray-on Concrete Slab Densifiers, Hardeners & Moisture Cures

Slab DensifiersThese products, commonly referred to as “slab densifiers,” are just different types of silicoid densifiers added to the concrete mix before the pour that have been on the market for over thirty years. They are finding new markets because of all the issues surrounding concrete moisture and moisture sensitive floor coverings.

Essentially they work exactly the same as the silicoids that are entrained into the concrete prior to its placement such as Read More

Remove Baseboards Without Damage

How many times have you damaged the walls trying to remove baseboards?

Maybe you’ve seen the damaging results of someone else’s efforts to remove baseboards from the wall. Or those craters on the face of the base when the nails have been pulled out? Who would have thought you’d ruin the board if you pulled a nail out the same way you put it in?

Now, far be it for me to think this article will be some great teaching instrument for the already accomplished flooring professional. It’s not aimed at pros because they already know this stuff. This is for the new helper, or maybe the homeowner, do-it-yourselfer and home improvement wannabe. It’s for anyone who has slapped their forehead when they realized it’s gonna take more than just a little bit of new base to cover the damages you caused when trying to remove baseboards with brute force.

Plywood Underlayment Direction

Impact of Plywood Underlayment Direction¹

By Frank Woeste and Peter Nielsen

Beginning in 2007, the TCA Handbook for Ceramic Tile Installation listed in bold print the following requirement for two-layer wood sheathing installation methods:

  • face grain of plywood shall run perpendicular to joists for maximum stiffness.

Should the tile contractor or other interested parties be concerned whether or not the plywood underlayment runs perpendicular to the joists? Read More

SLC & Radiant Heat Flooring

Self-Leveling Cement & Radiant Heat Flooring

When installing electric radiant heated flooring, you will find that every manufacturer has slightly differing recommendations in their installation guidelines. Following the manufacturer’s recommendations for installing the wires or mats is important. Following their guidelines for installing tile directly over these mats generally leads to frustration and in many cases an installation that has an inferior finish due to trying to set over a surface that is not flat, and sometimes one that has sensors that are thicker than the thinset bed you are trying to set tile into.

As a professional installer, I have found that installing the electric heat and following this with a Pour of Self Leveling Cement to a thickness of ? – ½” provides an excellent flat surface for tile installation and additional mass to retain heat. Once poured it also protects the Heating System from damage while setting tile.

The following method is what I… what my company, Tilewerks, uses: Read More

Ultimate Scraper Blade’s Spud Bar Review

The Ultimate Scraper BladeThe Ultimate Scraper Blade was introduced to the industry in 2004 by Skirted Blade Systems LLC of Lake Tahoe, NV. It was a hit with all who saw and used it, but like any new tool in this industry, it was slow to gain wide acceptance. Shown and demonstrated at Surfaces, the CFI Convention and other flooring events and seminars, it finally made national distributors late that first year and was available in the UK by November. But it wasn’t until May of 2006 that their latest incarnation of the little blade that could made its debut, the Ultimate Scraper Blade Spud Bar. Read More

Tile Underlayment Positioning

Positioning Underlayment to Prevent Tile & Grout Cracks by Frank Woeste, P.E. and Peter A. Nielsen

The 2003–2004 Tile Council of America’s (TCA) Handbook for Ceramic Tile Installation contains numerous details for a double layer wood floor system supporting ceramic tile. The thicknesses of the subfloor and tile underlayment are given in each case. Specific guidance on where to butt the underlayment end joints is not given for any detail. For example, for F142-03, the TCA Handbook states, “offset end and edge joints of the underlayment panels by at least two inches from the joints of subfloor panels; they should not coincide with framing below.” It further states, “underlayment fasteners should not penetrate joists below.” In the case of F150-03, the offsetting is not mentioned, but it does state, “underlayment fasteners should not penetrate joists below.” The same holds true for F155; however, it also states, “face grain of plywood should run perpendicular to trusses, I-joists, or sawn lumber for maximum stiffness.”

The purpose of this article is to propose specific guidelines Read More

Cement Boards Over a Slab

Using Cement Boards Over Concrete Slab Construction

It seems that ceramic tile installation has an abundance of myths that pop up all too frequently regarding Do-It-Yourselfers on “help forums” and DIY websites. So-called tile experts offer advice and opinions based on, well… I’m not sure what some of the comments are based on or where some people get their (mis)information to tell you the truth. I want to address the subject of installing cement board products over a concrete substrate.

It is imagined by some that products like Durock, Hardibacker and others can be used to fix imperfections in the surface of concrete or to override a previously painted or sealed concrete surface. Installing tile over painted or sealed surfaces is usually not good practice. Read More
