Tin Can Y'all Tile Over It?
Tiles, also equally the grout used to bring together, them aren’t waterproof. So, installing tiles in a moisture-prone expanse leaves them susceptible to moisture penetration. Waterproofing the substrate is a bang-up style to forbid water from damaging the tile in addition to your construction.
If y'all would similar to install a waterproofing membrane underneath your tiles merely do not know how to go about it, hither’s a take to assistance you lot through. I furnish information on how yous tin get most tiling over a waterproofing membrane and what to look out for when selecting a waterproofing membrane.
It is advisable to install waterproofing membranes underneath tiles, peculiarly inwards areas of high wet exposure, like bathrooms. Both liquid together with canvass waterproofing membranes are appropriate for role beneath tiles. Tiles should entirely live laid once the waterproofing membrane is completely dried.
Waterproofing Membrane Is Often Used Beneath Tiles
It is commonplace to install waterproofing membranes underneath tiles, especially in wet-prone areas like washrooms. This is because tiles and grout in these areas are at take chances of H2O penetration. If this happens, it can drive the tile to loosen upwards, encourage the growth of mold, together with can Pb to structural damage over time.
A waterproofing membrane prevents this from happening by creating a protective barrier betwixt the tile in addition to the substrate. This is why it is recommended that you lot employ a waterproofing membrane earlier tiling over whatever expanse that mightiness live exposed to moisture.
Types of Waterproofing Membranes
The type of waterproofing you lot use would depend on factors like the location, budget, together with skill of the installer. There are ii types of waterproofing membranes to take from.
- Liquid waterproofing membrane
- Sheet waterproofing membrane
Both types of waterproofing membranes serve the same purpose. They besides have their unique features as well as benefits. If you are considering toll, liquid waterproofing is the cheaper pick.
Sheet membranes offering more than durability together with force while liquid waterproofing has higher weight-bearing properties. Although it requires more expertise, sail waterproofing is easier to install than liquid membranes.
You could as well role a tile backer board (amazon link) or you could combine both the liquid in addition to canvass waterproofing membrane past installing the sail membrane and applying the liquid membrane over it.
How Soon Can You Tile Over Waterproof Membrane?
The dry out time of the waterproofing membrane is subject on a span of factors.
- The type of waterproofing membrane used.
- The atmospheric condition.
- Temperature in addition to humidity conditions.
- The state of the surface y'all mean to waterproof. Porous and cooler substrates naturally have longer to dry out.
- Number of coats used inwards the instance of liquid membranes.
- The place of installation. Is it indoors or outdoors? If it’second indoors, is the room good ventilated?
As mentioned, the drying time of liquid waterproofing varies based on the issue of coats used. Light layers tin dry out in a thing of hours but regardless of the issue of coats yous purpose, liquid waterproofing dries inside 24 hours. However, it could accept upward to 48 hours for it to cure completely.
Sheet waterproofing membranes accept longer than liquid membranes as well as postulate almost 24-48 hours to firmly adhere to the surface.
After 48 hours the waterproofing should be tile-prepare, regardless of the type of waterproofing membrane yous used. An exception would live if whatever of the factors I stated earlier prolongs the curing fourth dimension.
Will the Tiles Adhere to the Membrane?
Tiles tin can adhere to waterproofing membranes. In fact, they belike adhere meliorate than paint would if you were painting over your waterproofing membrane.
To achieve this, y'all would take to employ thin-fix mortar on the membrane before installing the tile.
Pre-mixed thin-prepare power not go the task done. So, I recommend that y'all get for powdered mortar together with do the mixing prior to application. If y'all role pre-mixed thin-set up it mightiness not adhere firmly to the membrane and this would consequence inwards a loose tile plumbing fixtures, which might come off in one case the mortar dries off.
When exposed for a spell, the mortar can dry out out. So, depending on the size of the expanse you think to tile, it’s best to mix the mortar inwards modest quantities.
Also, do not employ sparse-ready over a large surface area immediately, instead utilise inward bits and then that it doesn’t offset drying out before you lot install the tile. This way when you lot agree the tile onto the mortar, it would bond firmly alongside the substrate.
How to Tile Over Waterproofing Membrane
For tiles to adhere to waterproofing, the membrane must live properly installed.
Installing tiles over waterproofing membranes is quite like to installing them over regular substrates.
You volition involve the next items to tile over a waterproofing membrane.

| Grout float | View |
| Bucket | View |
| Mixing paddle | View |
| Rubber mallet | View |
| Tile cutter | View |
Steps:
- Wait until the waterproofing membrane is completely dry out earlier proceeding to tile.
- Mix powdered thin-set mortar inward pocket-sized batches and apply on the surface. While mixing the mortar, gradually add cool water to the powdered mortar and mix until it reaches a peanut butter consistency.
- Spread mortar evenly using a notched trowel.
- Install the tile to sit over the sparse-ready. You power take to use something like to a prophylactic mallet to tap them into place.
- Use epoxy grout instead of regular grout to make full the joints. Unlike regular grouts, epoxy grouts are waterproof, making them ideal for this type of application.
Helpful tips
- Prime the surface earlier applying the waterproofing membrane. This mode, the waterproofing membrane would adhere to the substrate too you lot wouldn’t take issues spell installing the tiles.
- A poorly installed waterproofing membrane would touch the tile installation, then it’second best to follow the manufacturer’s data while installing the membrane.
- Before installing the tiles, I recommend that you perform a inundation test at least 24 hours later installing the waterproofing membrane. This would help y'all ascertain the lineament of the waterproofing.
Good Waterproofing Membrane Options
The type of waterproofing membrane you function would live determined past factors like the type too location of the substrate.
For flooring installations, I recommend that you lot become for a waterproofing membrane alongside de-coupling properties. Their flexible composition would foreclose cracks from occurring.
I recommend the Schluter Kerdi 108 Sq. Ft. (amazon link) if y'all intend to go for a sail waterproofing membrane. It’s made from polyethylene, which is a choice cloth for waterproofing underneath tiles. The flexible membrane is impact resistant and it tin forestall cracks from occurring, making it ideal for a diversity of locations.
One downside of the Schluter Kerdi waterproofing membrane is its high toll. Also, the membrane might non adhere firmly to every substrate.
A peachy liquid waterproofing membrane is the Laticrete Hydro Barrier (amazon link). The waterproofing membrane tin can live installed both indoors together with outdoors. It tin can besides live used on both vertical in addition to horizontal surfaces. The waterproofing membrane offers load-bearing properties together with provides anti-fracture protection.
RedGard (amazon link) is another expert option for liquid waterproofing. People frequently function it to seal the areas around bathtubs and to waterproof drywall.
However, you lot’d have the live careful while applying it because it is quite sparse too could tumble off during application.
