How to Install Artificial Grass – Base Preparation
The base will need to be level and compacted as well have good drainage for the best results.
If you are installing on a tiled or concrete base such as a patio or rooftop you should be able to install directly onto this. Ensure that no major puddles form before installing.
When installing on an existing natural lawn there is a bit of work to be done first:
- Remove the existing lawn and poison the area (specifically on the edges) with something like roundup. You should be removing about 75mm-100mm of material.
- Level and compact the area, ensuring that there is a natural fall for the water to drain out.
- To compact the area you will need to slightly wet it and either hand compacter it with a hand stomper or a plate compactor.
- If necessary, install a subsoil drain on the natural fall side. A 75mm pipe would be sufficient for this. Ensure that once the pipe is installed you have covered and compacted over it.
- At this point you will need to bring in some porous material to build the area up to the correct height. G5 is ideal but anything similar from your local landscapers yard will work.
- Once you have bought enough material in you will need to level and compact the area
- If you would like to glue the edge of the artificial turf/ synthetic grass down you will need to get a 50mm cement edge in place.
Synthetic Turf Installation Process:
Firstly you will need to calculate your required materials by measuring your proposed site in 2m or 4m widths. From this stage you can calculate what length rolls you will require.
- Roll out the synthetic turf in your 2mm or 4m widths ensuring that each roll is rolled out in the same direction (double-check that the grains of each carpet is falling in the same direction)
- Trim the black edge of the turf with a sharp carpet knife to remove the outermost material (approximately 2-3mm from the first “rib” of yarn)
- Butt up each roll tightly next to each other to prepare for joining. You will ideally have a gap of 0-4mm between the two carpets; you might need to trim a little bit of in certain spots. Ensure you use a sharp carpet knife and take your time with this.
- Once they are fitted correctly next to each other you can open the joining area up by folding the edge of each carpet open so the black side faces up; being careful not to move the entire carpet.
If using DIY joining tape
- Roll out the DIY joining tape down the middle of the joining area so that when you put the two artificial grass carpets back down each carpet will be stuck to approximately 10cm of jointing tape. The silver side of the tape must face down.
- Peel open the jointing tape to expose the sticky tape.
- Begin at one end and fold down the two edges of the artificial turf carpet at the same time ensuring that the two carpets do not overlap.
- Press down to on the joint to ensure that the tape has stuck to the two carpets.
If using joining tape and glue
- Insert white joining tape down the middle and layer glue throughout joining tape without spilling over the tape. Only a thin layer of glue is required (2mm after spreading)
- Begin at one end and fold down the two edges of the synthetic turf carpet at the same time ensuring that the two carpets do not overlap.
- When the glue starts drying apply pressure to the joint to ensure a strong bond. If done correctly the joined area should look like a solid piece.
- If glue is spilt onto the artificial turf carpet it can be gently cleaned with lacquer thinners while the glue is still wet.
- Trim the edge of your carpet to fit the shape of your area by cutting through with a sharp carpet knife. Take your time on this.
- Once the joints are complete and you have trimmed your edges to shape you can apply glue to the edges if required by folding 50mm of the artificial grass back and pouring a little bit of glue on the base. Spread this glue with a tile grout spreader.
- Fold the edge of turf back over and let the glue set a little before applying pressure.
