Many of our customers have been asking us how Radiant Floor Heating Systems should be installed when using COMPOSEAL GOLD. When it comes to installing radiant floor heating, we go through a process called the “installation sandwich.”

As you go through the process of installing Radiant Floor Heating Systems, you can see that the flooring consists of a variety of layers. Like a sandwich, these layers stack on top of one another in order to function properly.

  • Tile
  • Latex modified thin set bond coat
  • COMPOSEAL GOLD
  • Latex Modified thin set bond coat
  • Substrate or Subfloor with embedded Radiant Heating System

So what is COMPOSEAL GOLD?

COMPOSEAL GOLD is a direct bond membrane made up of a high-density PVC, with non-woven polyester scrim laminated on either side of the 40 mil sheet membrane, for direct bonding to the substrate as well as the ceramic tile or marble above. It does not rot and is highly resistant to solutions containing salts, acids, and alkalis, as well as many organic solvents, alcohols, and oils. COMPOSEAL GOLD is used as a concealed crack isolation (anti-fracture) and/or waterproof membrane under thin-set installations of ceramic tile and marble, terrazzo and brick; for new construction, remodeling or repair, residential and commercial, in kitchens, restaurants, resident entries, steam rooms, radiant heated flooring, shopping malls, etc.

Negligible shrinkage at extreme temperatures, -20° F to 212° F, makes COMPOSEAL GOLD especially ideal for Radiant Heated Flooring Systems. Its scrim is designed specifically for direct bonding on both sides of the “sandwich” in ceramic tile and dimension stone installations. This serves as a Crack-Isolation (uncoupling) membrane that provides adequate support/load distribution for your tile covering, and allows the heat from the system below to radiate up through the installation into the room.

*Always consult with the manufacturer of the radiant heating system for their specific installation instructions for installing radiant heating under ceramic tile.

Step 1: Expose the Subfloor

Remove the old carpet, leaving the subfloor exposed. If necessary, use a scraper to separate the carpet from the floor. Remove excess glue from the cement subfloor with scrapers and an appropriate solvent, making sure to follow the solvent directions.

Step 2: Apply a Crack-Suppression Membrane (COMPOSEAL GOLD)

Following the manufacturer’s instructions, apply adhesive to the concrete subfloor and lay down the crack-suppression membrane. Apply the adhesive in sections and unroll the membrane onto the floor, using a floor roller to press it flat and work out any air bubbles. Since concrete expands and contracts as the temperature changes, this membrane will help support the floor and prevent cracks in the tiles or grout.

Step 3: Install the Grids for the Radiant Heating System

Install the plastic grids that will hold the radiant-heat wires, using hot glue to adhere the grids to the subfloor. Follow the manufacturer’s instructions, and space the grids uniformly over the floor to prevent hot and cool patches.

Step 4: Snap the Cables into the Grids

Snap the radiant-heat cables into the grids, keeping them evenly spaced to prevent hot and cool patches in the floor. Check the manufacturer’s instructions for guidance on how far apart to space the cables.

Step 5: Mix and Spread the Thinset Mortar

Use a heavy-duty drill with a paddle bit to mix Thinset mortar according to the package instructions. Use a straight-edge trowel to apply a layer of mortar over the electrical cables. When mixed to the correct consistency, the mortar will stick and mound on the trowel without falling off. Make sure to hold the trowel at a consistent angle throughout the job so the mortar bed will have a uniform thickness. Allow the mortar to dry thoroughly before proceeding. Wet or cold weather will slow down the drying process, and below-freezing temperatures can keep the mortar from curing properly. Consult the manufacturer’s instructions for guidance.

Step 6: Power the Radiant-Heat Floor

The best way to power the radiant-heat floor is to hire a licensed electrician to run a dedicated circuit from the home’s main electrical panel to the correct room. The electrician also can install the control panel/heating sensor in the wall.

Step 7: Determine the Layout

Dry-fit a vertical row of tiles and a horizontal row, leaving space for grout, to determine the best layout. The ideal layout will use as many full tiles as possible. The tiles against the wall should be a half-tile wide or wider.

Step 8: Spread Mortar and Lay the Tiles

Spread mortar on the floor, using the notched edge of the trowel to create deep grooves in the mortar. Press each tile into the mortar, wiggling it gently to seat it. Check the tiles for level and adjust as needed. Use tile spacers to keep an even grout line. Use a wet saw to cut tiles as needed for the perimeter of the floor.

Safety Alert: Always wear safety glasses and use caution when working with a wet saw.

Step 9: Mix and Apply the Grout, and Apply Sealant

After the mortar is dry, mix the tile grout according to the package instructions and apply with a grout float. Use a diagonal motion to apply the grout, working it into the spaces between the tiles. Let the grout dry slightly, then wipe the excess off the tiles with a damp sponge using a diagonal motion.

Let the grout dry completely before sealing. Once the grout sealant is dry, move the furniture back into the room. Let the mortar cure for four weeks before using the radiant-heat system.

How to Properly Tile a Roof Deck

How to Properly tile a Roof deck using Composeal Gold

composeal gold, Pan liner, sheet membrane, waterproofing membrane, waterproofing membrane

When installing ceramic tile on roof decks, the most important single thing to remember is that a roof deck is just that , a roof – a barrier against the elements, and especially water.

“It’s only a roof deck!” Did you ever hear that statement? When and if you do, be prepared for problems, and very possibly big ones. Where roof decks and concerned, roof is the most important word. When it comes to keeping water out, how the roof deck is constructed is at least as important as the balance of the roof itself, since both must satisfy the same requirement to keep the rooms and equipment below them dry.

SOME BAD EXAMPLES

A roof deck was leaking badly. Upon investigation, it was found that the installation had been made using one of the methods described in the Handbook for Ceramic Tile Installation. Why, then, the leakage? The method selected was one involving a cleavage membrane, and it had been chosen even though some of the other methods contained in the Handbook called for a waterproof membrane. The purpose of the cleavage membrane, as you will recall, is to isolate the tile floor from the structure, not to serve as a waterproof membrane.

Another somewhat similar project was purposely installed over a cleavage membrane consisting of a single layer of roofing paper. Those responsible for the installation thought the horizontal tile were waterproof, and therefore did not need a waterproof membrane. But while ceramic tile floors do not disintegrate when wet, they are not waterproof. A good waterproof membrane like Composeal Gold Crack Isolation Waterproof Membrane  is the only insurance against water damage in the rooms under a roof deck.

Two residences came close to taking the prize for most water damage. Built by the same contractor for two sisters, the houses faced each other, with a street in between them. The houses were already completed, with carpets, furniture and kitchen equipment in place, but before anyone could move in, the rains came – heavy rains. The resulting damage to ceilings, walls, furniture and carpets made the homes impossible to occupy. Much of the water came down in the kitchens, where cabinets were soaked, discolored and warped out of shape. What had happened? Each house had a rear, exterior, second story, tile deck which sloped the wrong way, toward the house, with nothing to prevent the water from going through the metal sill of the large sliding doors and into the structures.

Yet another common shortcoming in deck construction is the improper placement of flashing, or even its complete lack, at the junction of the walls and floor. A number of leaky decks have been found in which the lack of flashing has been the cause of the leakage.

Recently, an owner was having problems with leaks in a tiled deck. It started with leaks in the first deck to be installed; after the first deck was replaced, the new deck also leaked. The owner called for advice on how to make sure a third deck would not leak. She was advised on how the deck should be constructed, and was also urged to water – test the Composeal Gold Waterproof Membrane before installing the ceramic tile. The water test had to be stopped immediately because of the torrent of water that flowed into the room below. It is hard to understand how workmen can be so careless or lacking in knowledge as to allow such a membrane to be water- tested. The roofer had terminated the waterproof membrane *” short of membering up with the roofed-over part of structure, and the builder had done nothing to flash and waterproof that joint prior to the water test.

SLOPE ON STRUCTURE

In 1956, working with the International Association of Plumbing and Mechanical Officials, sponsors and authors of the Uniform Plumbing Code, tiled shower floor receptors were at last properly engineered and made part of the Uniform Plumbing Code.

The important part of this engineering called for pre-sloping the floor of the shower prior to placement of the waterproof membrane. The waterproof membrane was then placed in the pre-sloped surface so that the membrane itself sloped- – *” per foot minimum, *” per foot maximum- – to the weep holes in the bottom portion of the floor drain.

Prior to this, it had been customary to place the membrane flat, thus allowing seepage water to accumulate with no way to reach the weep holes and go down the drainpipe.

Shower floors are smaller than roof decks, but the same engineering principles apply. Slope the structure and Composeal Gold Waterproof Membrane to the weep holes in the floor drains; if there are no floor drains, slope to the open scuppers, with nothing in the bottom of the scuppers to prevent the free flow of seepage water.

FLAT DECK STRUCTURES

No matter how hard we try to spread the word about sloping them, structures continues to be built flat. The point of sloping the structure, which in turn slopes the membrane placed upon it, is to eliminate seepage water via the weep holes or open scuppers. The tile trade uses dry-pack floor mortar, and when this is placed on the flat waterproof membrane, the slope is only on the top surface of the dry pack. The dry pack is pumped out by the hot sun, leaving the salts of efflorescence on the tile. At least one company’s remedy for flat roof construction is to pre-float the roof deck with the dry pack mortar, which is then cover-cured. A waterproof membrane, designed to be used with a thin-set bonding system, is bonded to the mortar bed and fastened into the clamp-style floor drain. A compatible bonding mortar is then used to bond the tile to the membrane.

A SEEPAGE CHANNEL

In the design of roof decks, an effort has been made not only to slope the roof deck, but to create a channel which makes it easy for seepage water to flow toward the drain and into the weep holes. Until quite recently, the standard channel consisted of a layer of crushed rock over the waterproof membrane. A layer of cloth, such as burlap, was then placed over the crushed rock to prevent the mortar from filling up the voids in the crushed rock when the mortar bed was installed.

Now we have matting to provide that channel. The matting comes with a flannel – like cloth covering, which is installed cloth side up to prevent the mortar from filling in the extruded nylon and black spinnerette fibers. This type of matting has a long history of successful use in providing weep channels under concrete in drainage ditches and in similar situations.

An installation showing the use of the channel to promote water runoff is contained in the Handbook of Tile Installation. Even though this is the recommended way to install tile on roof decks, in actual practice, the channel is not always used. No matter what is done, however, positioning the waterproof membrane on a slope to the weep holes, or open scuppers, is the most important requirement for roof deck construction.

WATER ACCUMULATION

If the walls surrounding the roof deck are properly flashed at the juncture of deck and walls, and drip screeds are used, some water is going to drain across the tiled deck in addition to the rain which falls upon it naturally. However, it is best to not use the deck as a collection basin for water drainage; on the contrary, as much water should be kept off the roof decks as possible.

Directing water to the drains or scuppers takes some planning as to the positioning of those structures. Getting the water to move requires a slope of *” per foot. One – eighth of an inch per foot will drain the water, but will take much longer to do it; *” per foot, on a long run, may not be achievable because of the thickness build-up from the furthermost distance from the drain to the drain. To prevent problems, planning is needed as to the placement of the drains, as well as the height of the tracks for doors and sliding doors. Many, many times we have received calls describing situations in which only *” is available at the doorway to install a 2″ thick tile installation, and there is no way to drain the deck.

SUMMARY

“It’s only a roof deck!” As can be seen from the foregoing, construction of a roof deck takes planning. It is not difficult; it just has to be planned. It can also be seen that proper planning and execution require the cooperation of several trades working together.

A leaky ceiling or wet basement is a huge problem which, a lot of homeowners are facing these days. It can cause damage to furniture, walls and floors. In addition the dampness also attracts wood rot and termites which can aggravate the damage caused. Since home is probably a person’s most expensive investment, it is important that homeowners take adequate measures to prevent damages to their house. Waterproofing is an important measure you can take to prevent water from damaging your house, eventually safeguarding your investment as well as the house. Some of the popular waterproofing options you can use include vinyl (composeal) and fabric (Schluter and Blanke). These can be used for basement, foundation, floors, walls, leaking ceiling and other sections of the building structures.

Whether you are building or remodeling your home, you should install waterproofing system to prevent penetration of water. Vinyl (composeal) waterproofing system is quite popular with homeowners as it is long-wearing and lasts for decades. Along with durability, it is easy to assemble and very affordable. The Composeal vinyl fabric provides protection against common shrinkage cracks, common in houses and prevents moisture migration as well as water damage. Moreover, it has an excellent bonding strength and can be easily installed on terraces, roof decks or any kind of flooring, including marbles, tile, stone or brick. In addition, it also provides excellent resistance against chemicals. Only drawback is that the place should be well ventilated as this fabric does not breathe, and if the underside of the fabric gets wet then it might lead to mildew growth.

Use polyurethane sealants to repair cracks effectively

Cracks in the walls or on the floors can be a matter of serious concern. Not only do such cracks affect the aesthetics of your house, but they can also result in water leakage, thereby causing significant damage to your house. You can either call in an expert repairman to fix the cracks in your walls and your floors, or you can undertake this task yourself. Although a number of serious cases of cracks would require you to call in an expert, minor cracks in your basement or on your concrete slabs can be easily fixed by using a polyurethane Sealant.

Polyurethane is an organic compound that has excellent corrosion and moisture resistance qualities. Further, polyurethane is also effective as a heavy duty adhesive and is ideal for coating. It is for this reason that polyurethane sealants are widely preferred for repairs and waterproofing in both commercial as well as domestic sectors. Apart from its heavy-duty adhesive and waterproofing properties, polyurethane is also renowned for the flexibility it offers when applied over joints.

This flexibility comes in handy while using over concrete joints since concrete expands and contracts due to temperature changes. If a concrete crack is not treated in time it would get worse and could result in significant damage in the future. What makes a polyurethane sealant more effective while fixing cracks in concrete is that it is generally applied using a caulking gun. This makes it significantly easier to fill in the cracks with the sealant, thereby resulting in effective repairs.

Polyurethane sealants are also ideal to repair cracks in wood floors due to its various benefits. Polyurethane offers excellent abrasion resistance as well as scuff resistance, thereby making it ideal for use on wood. The use of a polyurethane sealant on wooden floors will ensure an effective waterproof and water resistant layer.

Polyurethane sealants have very high viscosity and can easily seep into even the minutest cracks to form an effective and waterproof seal. This is especially effective in case you find minor cracks in your basement wall. Although, a crack in the basement wall could be due to improper foundation, but in case you find that it is not a foundation crack you can easily use a polyurethane sealant to fix the problem. Further, since a polyurethane sealant can easily expand and contract, your basement crack will be effectively sealed and will remain waterproof for a long time.

A high quality polyurethane sealant will effectively adhere to different surfaces such as wood, masonry, concrete, steel as well as aluminum. The polyurethane seal will remain flexible as well as corrosion resistant for a long time. You can even paint over a polyurethane seal to ensure that the aesthetics of your house are not affected in any way. It is due to the excellent adhesion qualities as well as the other additional benefits that are offered by a polyurethane sealant that these are becoming the preferred choice for home renovation and repair work.
