Invisible Waterproof Agent 100g, Transparent Insulation Sealant, Clear Waterproof Coating Agent Anti-leakage Repair Spray Glue Grout Sealer for Outdoor Home Bathroom Roof Gutter

Bought this due to water leaks in the cracked grout between the ceramic tiles in my bathroom shower. Goes on very easily and turns hard and transparent after drying so you don’t even notice where it was painted on. It has completely sealed up the cracks and provided a waterproof protection. In fact, the wall on the other side of my shower is now drying out beautifully as the dampness was building up and paint was coming off, saving me hundreds in a new plastering job. Absolutely guarantee this product to anyone that needs this for sealing grout between ceramic tiles in bathrooms kitchens.

Was having issues with some old wooden windows which let water in when it rained and cold air in the winter, leaving the house feeling really cold and 'wet'. Can't afford to have them replaced yet and found this 'quick fix'. Wasn't convinced it would work but, wow! extremely impressed. Filled in all the gaps around the windows and immediately noticed the difference. It definitely feels 'less cold' and not a single drop of water has seeped through even though it rained really heavy. May not last long, but it certainly does the job in the short term. Will be purchasing again to seal over the tiles in the shower.I purchased the 300g pot which was a good size and managed to do all 12 windows (of average size) and the french doors. Pot contains a thick, creamy, white liquid. Goes on purple, but dries clear (love that as you can see exactly where you have brushed it and what you may have missed)Instructions are confusing, as it says 'spray', bit after a google search I found you just paint on and leave to dry - easy! Brush is 'tiny', but was useful for the small corners of my windows. Will use a larger brush for the shower. Easily washes off the brush with warm water.

This is my second tub of this.It meets my needs for the little jobs.Its easy to use,just brush it on.I have used this on my birdbath and it solved the problem.It dries clear so cannot be seen.I really like this product,it does what's needed.Thank you

Very small tub with brush. Used to seal concrete step outside door. Easy to use but it went on purple then turned white so I initially thought I had ruined the step, but luckily it dried clear & set hard & did the job i needed it for

I bought this to tackle a few problem areas around my home, like some fine cracks in my bathroom grout by the shower. Using it was surprisingly simple—application with the brush was quick and easy. It dried clear, which I loved because it didn’t change the look of anything I treated. The real test came when I ran the shower and I was thrilled to see everything held up perfectly—no leaks or water spots at all. This product definitely exceeded my expectations and is worth keeping on hand for future repairs.

Invisible? What a load of rubbish. I painted a small leak in a bird bath, the natural look of the bath is replaced by this white blue sheen and the bath still leaks. Having watched how you paint the stuff on to a plastic draining bowl to seal all the holes then put water and fish into the bowl I was sold on the stuff. So a small 1mm crack should be an easy fix. I am now on the third coatand still have a leak. Utter junk.

I've put this above my front door which is hammered during heavy rain with small cracks in the render allowed water to seep through onto my new white wallpaper inside and now stained. Putting it on is easy but I don't quite understand it turned a purple colour. I waited a while and it then says to spray with water. I have done this and could see the water running off easily but my bricks are now white but the purple hue has gone. I really do hope the bricks go back to their original colour. It is very expensive the pot is very small. Let's see if no more water seeps through to inside the hallway. At the moment it has totally ruined the front of my home I hope it wears off soon and I will think again.

Good product. Does what it says on the tin.
