When using HYDRO BAN®, 9235 Waterproofing Membrane or HYDRO BARRIER™, tile can be installed as soon as the final liquid coat is completely dry to the touch.
Wait 24 hours after the membrane installation is complete to allow for the final set of the mortar and to ensure waterproof performance of the assembly at seams and connections before water testing.
The product is dry when it turns solid red with no pink showing, normally 1-1/2 to 2 hours. Depending on ambient conditions, drying time can take up to 12 hours. A water test can be conducted 72 hours after application if required. Clean tools and hands with water before material dries.
Once your room has been waterproofed and left to cure for 24 hours, the tiling process begins.
In conclusion, you can tile straight onto waterproofing provided the surface is non-porous and smooth. If you are tiling onto a porous surface, such as concrete, make sure to seal it first. And if you are tiling onto a rough surface, such as brick, make sure to smooth it out first.
Wet Rooms And Bathrooms
If you're waterproofing a bathroom, count on it taking 24 to 72 hours to dry. If you can, try turning on any fans or opening windows as soon as possible to ensure good ventilation.
For tile installations bonding directly to the substrate; strongly recommended to apply at least one full coat of "undiluted" RedGard® to the "dry" primed area and allow to dry completely before tile installation work is to begin. When used as a vapor barrier, apply one full coat (70 sq. ft.
Wait 24 to 48 hours before tiling. The drying time is important for a strong hold. Fully bonded mortar means your cement board won't flex. This protects your tile and grout from cracking.
APPLICATION OF THE PRODUCT Mapelastic AquaDefense must be applied in two even coats (minimum 0.4 mm wet film thickness per coat) with a long-haired roller, brush or trowel.
Mapelastic AquaDefense is ready to receive thin-set mortars for tile or stone when dry to touch (about 30 to 50 minutes after applying second coat).
You can almost always alleviate this issue by pointing a pedestal fan into the waterproofed area and keeping the window(s) and/or door(s) open. Increasing air flow will also assist if other factors such as temperature or humidity are less than ideal.
Whether you're sprucing up your existing bathroom or starting from scratch with a wet room, one thing's for sure: waterproofing is an essential step in the tiling process. Sure, it may not sound like the most thrilling aspect of the project, but trust me, it's crucial if you want to avoid future water damage and leaks.
Mapelastic AquaDefense dries after about 30 to 50 minutes and is then ready to receive any MAPEI polymer or epoxy mortar. Mapelastic AquaDefense can be flood-tested after 12 hours of drying time, is IAPMO-listed for use as a shower-pan liner, and exceeds ANSI A118.
How long do I have to wait before I can install tile on the Schluter®-DITRA membrane? Once DITRA has been installed on the substrate, tile can be installed right away. No need to wait for the mortar to cure.
As the rains subside, it makes for the perfect time to work on waterproofing your home. With no high temperatures and harsh rains to disrupt the process of waterproofing your home, you get to rapidly protect your home in time.
One thing to remember about cement board is that it can be highly absorbent. Without any moisture-resistant properties, it may cause mold and fungal growth if not covered with a waterproof layer before adding tile – especially in areas of high moisture, such as bathrooms.
While thinset is technically a modified mortar, it's thinner and designed specifically for tiles, unlike mortar which is thick and holds stacked bricks in place. Likewise, thinset contains cement, but its formula lacks the strength to build walls or even serve as a stand-alone flooring product.
Many people suggest a minimum cure of 28 days under normal conditions, although most thinset manufacturers say you may get away with 14 days using a premium latex modified thinset.
Ambient and surface temperatures must be above 40°F (4°C) at time of installation and for 72 hours after application. Tile over membrane within 72 hours in exterior applications to avoid extended exposure to ultraviolet rays.
The adhesive mortar (thinset) used for installing RedGard Fabric Membrane must be appropriate for the substrate and should thoroughly embed in the RedGard Fabric Membrane.
The thin-set mortars recommended for waterproofing membranes are polymer-modified thin-set mortars. Do not use mastics such as Type 1 or Ultramastic ECO on waterproofing membranes.
On Wall / Vertical surface the application should be minimum 300mm above the gola/cove line. Cure for 3 days by jute sacks after 6 hours of final coat. After curing test waterproofing for 4 day by water ponding.
Ventilation. Good airflow helps the removal of moisture, speeding up drying times. Proper ventilation, especially in enclosed spaces, leads to more efficient evaporation.
Wind, airflows, humidity, fog, snow and rain all have their own issues when it comes to using liquid membranes and can severely affect the future performance of the applied waterproofing coat. Water falling onto waterborne and cement-based membranes can mean they don't dry properly and potentially can be washed away.
