Laying mulch over grass will include the following steps.
1. Remove Weeds From the Lawn
First of all, remove all weeds from the lawn manually or using preen, if any along with their roots plus remove bulky or woody plants from the place. Plus remove invasive plants which are of no use from your garden or area where you want to lay mulch over grass. Plants like horsetails, oxalis, or Kikuyu are those you going to remove. Be careful while removing these plants so you do not damage the plants you wanted to keep.
2. Watering the Area
Now water the whole garden area to keep the natural decomposition process active.
3. Cut a Clean Edge Around the Lawn
Now cut the lawn 7 to 8 inches from the edge of the concrete using an edged shovel to keep the lawn away from the concrete. This will help in avoiding runoff of mulch from the lawn towards the concrete. While making the edge, the soil should be 3 inches below the floor of concrete.
4. Spread the Newspaper or Cardboard Over the Lawn
Now spread newspaper or cardboard over the soil. The newspaper should be 10 to 11 layers thick. Because the layer of newspaper thicker than this can stop oxygen contact with soil. Or you can place simply spread one layer of cardboard all over the garden. Use white and black newspapers only, and avoid using multicolored newspapers as they can harm the soil. Newspaper and cardboard will simply decompose to soil and helps in creating better quality soil. Make sure no lawn area shows while placing cardboard if it is.

5. Watering the Cardboard/Newspaper
Now wet the cardboard by watering it. The water holds the newspaper/cardboard firmly to the ground. Plus newspaper will help in blocking sunlight to soil and so help in stopping weeds growth. Do it all with proper care so that newspapers will not shift from any area. It will also help in laying mulch over grass properly.
6. Spread and Compost Mulch Over Newspaper
Now lay mulch over the newspaper. Lay mulch over cardboard or newspaper properly to save wet newspaper from tiring apart. Also, select the best mulch type. You can use organic mulch or inorganic mulch depending upon your garden need. Plus make sure your mulch would be 4 to 5 inches. When you finished laying mulch over the garden water it again. You are all done with laying mulch over grass.
