Tips on using Stickit Tile Repair Kit

Posted by

We're often asked the same questions about injecting Stickit Tile Repair Adhesive so we thought we'd share our experience and make some suggestions

Q Do I need to place a weight on the tile after injecting Stickit Tile Repair Adhesive?

A It depends! If your tile is very loose and has moved or is raised then it is a good idea to place a weight on the tiles after injection. This will eject any excess adhesive back out the injection holes and allow the adhesive to cure faster - but be careful to wipe up as you go or this can create a large mess. It will also make sure your tiles cure at the correct height as injecting large amounts of adhesive can sometimes lift your tiles if they are very loose to start. If your tiles are hollow but don't appear to have lifted or moved then placing weights on the tiles isn't going to help.

Q Can I walk on the tiles after injecting?

A Yes but you will achieve the best result by keeping off the area and allowing the adhesive to cure fully. The Stickit adhesive is designed to last and be used for multiple jobs, so if possible, treat one section and allow to cure, then treat the other area/s.

Q Can Stickit be used with under tile heating?

A Under tile heating has the advantage of raising the temperature of the tile and the substrate. Stickit Tile Repair Adhesive cures by way of evaporation and curing will be assisted by elevating the temperature. Turning the under tile heating on after injection is a good way to speed up the cure. We suggest turning off the heating before drilling injection holes and place a piece of tape around the drill bit at the correct depth after drilling the first hole as this will give you a visual guide of the depth required for drilling subsequent holes.

Q Does Stickit work on all tiles?

A Stickit will adhere to most types of tiles and requires at least one surface to be porous (eg. the underside of the tile or the surface it is laid on). Curing is more rapid on tiles with a porous underside such as ceramic, terracotta and porcelain. For less porous tiles (eg. slate or marble) curing can take significantly longer as the water vapour takes longer to evaporate out from under the tile. Raising the temperature by using a small heater or turning on under tile heating if available will assist curing.

Q Your suggested coverage rate is 5m2 per litre of adhesive so why am I using more?

A Based on our experience you should repair approx. 5m2 of floor tiles per litre, but this does depend on a number of factors such as the size of the gap between the tile and the substrate, the porosity of the surfaces, the underside profile of the tile, the size of the notches used to spread the tile adhesive, etc. In most situations loose tiles have debonded but still rest in place and the air gap between the tile and floor is only 1-2mm. If hollow tiles are not repaired over time they will typically lift higher and grout will start to crumble and crack. In some situations there has not been provision for expansion of the tiles and they can 'tent' or lift at the edges. Where large gaps have formed underneath the tiles more adhesive will be required. Where edges have lifted it may be necessary to remove a grout line to allow tiles to lay flat again before repair.

Q My grout is cracked and missing - how do I use Stickit?

The Stickit Tile Repair Kit comes with a small rubber plug which is used to create a seal around the injection hole so the adhesive can flow under pressure underneath the tile. If grout is cracked or missing the adhesive will take the path of least resistance and may flow out of the grout lines instead of spreading under the tile. If the grout lines are in very poor condition we suggest re-grouting before using Stickit. Once the grout has been repaired and dried you can drill through this and use the rubber plug to create a tight seal to force the adhesive under the tiles.
