Tile Grout

[Studdlygoof]

Was looking at tile grout today....whats the difference between sanded and non-sanded grout...and is there a better one for use in the Vivarium setup?

Anybody have any experience with painting the grout after its dry...not full out cover it but possibly airbrushing in some effects such as lichens and shadows to add a more realistic effect...if so, what is the longevity of the paint staying on after time...what types of paints....any type of sealers?...thanks

I don't have any experience with grouts, paints, or sealants, but I think that would look awesome if it could be done.

A lot of time has passed since this post but for the sake of information ill comment anyways. i use acrylic paint when i paint anything. generally before you apply any kind of sealant so ultimately it doesnt really matter much because it will be sealed underneath. As far as air brush or not also really doesnt matter, its more so how you seal it after then your method of application. Acrylic paints are non toxic though. I dont have airbrush equipment so I just mix a a small amount of grout and some acrylic paint to it to add color and apply it where I want it after I have put on my final coat of grout covering the whole background. Then i just paint it on to highlight certain areas. You can also buy satin acrylic sealant which leaves a nice non-shiney finish.

Difference between sanded and unsanded grout. Sanded grount contains sand and is for bigger gaps between tiles and is stronger due to the sand. Where as a unsanded grout is for smaller gaps, usually used on marbles and granites bcause you tile them close together and dont want to see the grout.

As for the paint i assume you could paint it but grout does come in a wide variety of colors. Depending on purpose you would also have to seal your grout if exposed to moisture.
