Hi there,
I need to use some gripfill to secure some small LED lights into thermalite bricks. The gripfill recommends to seal porous surfaces first with a suitable sealer, to which I bought some PVA.
I mixed 1 part PVA to 5 parts water and brushed the solution over the required areas on the thermalite bricks. But do I need to apply another coat or can I just go ahead and use the gripfill after sealing it once?
I'm just worried the gripfill wont stick very well.
Thanks in advance.
