PEBEO 766308 Gedeo Waterproofing Agent, Transparent,75 ml (Pack of 1),Yellow

The colour is an issue for me as I was working with white objects. It does dry and become less yellow but the tinge of yellow is still apparent. When it gets wet it becomes more yellow which might suggest it isn’t fully waterproof. I’m going to look for something more appropriate for my needs.

Quality for a good price. I was not sure it would be completely waterproof as I used air drying clay with acrylic paint, but it is excellent! I can leave the water in the bowls for days at a time and there is not a crack!

I have now used this for more than 2 years. I have used it on terracotta pots to seal the inside or the outside to be able to paint / decoupage them. The seal has to be applied evenly but sparingly and indeed, I have not found any leaks or damages to my decorated pots due to water penetration. If you overuse it i.e. you put too think a layer which is possible only if you waterproof on the inside of a pot and you leave excess at the bottom, then the seal retains this yellowish colour. However, it works brilliantly used on the outside of natural terracotta pottery.

Perfect for waterproofing my clay creations.

Did the job well.Bought to coat a terracotta pot that was being given as a gift.Applied it and it was yellow but once dried it was clear.
