Bostik Cementone Render Repair Mortar 10kg - Durable Repair & Patching Mortar - Ready Mixed, Just Add Water - Ideal for Weather & Impact Damage - Interior & Exterior Use

Q: what do you use to mix this?

HI I mixed water with a little PVA adhesive but advise using approx 1kg at a time make a mix So the cement is quite sloppy as ir dries in about 30 mins don't make too much at once or it will Dry out before you can use it. To keep it workable I used a mist sprayer to smooth the surface spray to make soft again. I used a normal brick trowel to mix with the water , I bought some Different sized plaster trowels to apply, if you paint the wall with a 50/50 PVA water mix prior to Applying render it makes the wall sticky and easier to apply. It says don't add water if mix becomes too Dry but I did with no problems important to get right consistency for use. Hope this helps

Q: HI can this be used for laying slabs and is it frost resistant? Thanks

I think not. The mix would not be right.

Q: Hi is this correct to repair a leaking chimney on the roof?

It depends on the scale of the repair the slope of the surface. It will probably work if you mix to a very thick consistency and if necessary box in the repair until it has set.

Q: Can I use this for roof tile ridge repair? If not, what other product can you advise.

Perfect for ridge repair. Used 4 months ago ,use quickly as sets quick,so a little at a time .
