Grouting sawn sandstone internal

[On one]

Thanks to everyone for the advice. The sealant I used was very thin so obviously penetrating. Interestingly cleaning the tiles was fairly easy prior to sealing ( 2 weeks of dog footprints) so I wasn't expecting grout to be so much of a pain. Don't feel I can change the sealer type (reaction?) to a thicker surface type. Plan is to seal twice more then add bal protective seal. This is water based and washes off. Then grout with a bag (funnily enough wife's suggestion). Does this make sense? Else get someone else to do it!

Not quite sure what the Bal Protective Sealer will achieve. If you have adequately sealed the stone,that should be sufficient. The 3 previous occasions I have used Bal sealer(on riven porcelain)it has been none too successful.

Hello, I'm sorry to hear that because I've just spent £25 on it... Out of desperation really. I thought it was effectively "grout release". I searched these forums and it seems to be well regarded. For what it costs and a few hours work I will try anything - may even take up praying. I am taking everyone's advice and will seal and seal again with the permanent solvent sealer and try and use a grout bag. Next weekends work. Many thanks Mark
