Both technical and aesthetic, the installation of tiles, ridges, or edges is not a step to be taken lightly. Indeed, if they are poorly sealed or improperly installed, water infiltration through the roof can occur. Optimal tile sealing thus prevents any water infiltration, ensuring roof waterproofing, preventing streaks and stains by allowing the runoff of edge waters, and ultimately enhancing the roofs and the building itself.
Solution
PROMPT natural cement, used in combination with lime, is employed for sealing tile ridges, edges, and creating flashings. The mortar of lime and PROMPT natural cement brings aesthetics (the mortar can be colored), quick execution, and preservation of old or natural substrates. PROMPT natural cement also allows for application in cold weather, significant thicknesses, and securing of mortars in case of rain (no streaks).
Technique
First and foremost, prepare the support. Moisturize both the substrate and the elements to be placed with clean water to enhance adhesion. Then, prepare the mortar of lime and PROMPT natural cement. Dry mix the PROMPT natural cement, lime, dry sand, and TEMPO retarder to homogenize the mixture, add water, and knead until obtaining a consistent paste. Proceed to implementation. Lay the mortar by pre-shaping the tile's form, then place the tile, stabilize and compact it. Tighten the mortar well to ensure aesthetics and water tightness. Remove excess mortar to achieve a smooth appearance. Clean the tiles to remove all traces of mortar.
How do you apply mortar to seal roof tiles?
For best results, place the mortar in the desired position, shaping it into a rounded mound. Then position the tile on top, hold it steady and press down firmly to ensure a good bond.
Press the mortar down firmly to ensure a neat finish and a watertight seal, then remove any excess to achieve a smooth, even surface. Next, clean the tiles with a damp sponge to remove all traces of mortar and achieve a flawless finish.
How long does the mortar take to dry?
When using Prompt Natural Cement mortar on its own, the drying time is extended by using TEMPO to allow for a working time suited to the duration of the project.
Thus, setting times with TEMPO are 20 minutes at a temperature of 30°C, 40 minutes at 20°C and 80 minutes at 10°C.
Using a Vicat PROMPT natural cement mortar for tile sealing provides :
- Aesthetic appeal
- Mortar security in case of rain
- Preservation of old and natural substrates
- Quick execution
PROMPT natural cement is used for sealing tiles, but also for all kinds of sealings such as sealing joineries, hinges, and shutter stops, as well as outdoor furniture sealings.
