Paving Grout

After cleaning and removing the lichen patio opening it needs sealing and injection re any help please Clive

Rake all joints loose and black brush the pavement below and then apply the new grout. Buy ready mixed injection / masonry and re-injection join each hand using an injection tool. If the weather be cold as you cover the new paving grout to prevent freezing - old sacks, tarp or rug will do.

If you mix your cement as the previous person said you're sure to get wet cement on the pavement, I would mix 4 to 1 sand cement dry after cleaning brush seals dry mixture into the joints with a soft hand brush and give it a very light touch with water and leave to set up

First, get hold of two pieces of cardboard about 9 inches 18 inches XBY. And some pieces of 2 x 1. Get a plateau, the background is 2 bits of hardboard with a gap of 1 / 2 inch, the X1 2 forms on the sides. When using, you position the gap 1 / 2 inch on the hinge that you want to grout grout place on the shelf, and drag the grout in the joint ... no mess.
As for the "grout, I use 3" Sharp sand to 1 cement, then instead of water, 1 part PVA adehesive 1 part water. Sticks, such as dung on a blanket, never goes .... then a good seal ....
