Installation onto compact earth:
Mark out the area that is to be covered;
Using a turf cutter remove the turf to a depth of 2" and weed kill area;
Where there is not an edge or a wall to butt grass up to, install the everedge edging system or fix tanilised timber battens around perimeter using wooden stakes to secure, to create a boundary;
Prepare the ground, i.e. remove humps and bumps leaving natural falls. Should the area have drainage problems, we recommend a type 1 stone base and possibly soak-aways are installed;
Chamfer the outer perimeters to a drop of 40mm from edging height. This allows the grass to run neatly into the edging system or perimeter edge;
Once area has been levelled, install 10-15mm depth of 6mm to dust granite stone (damp) or alternatively sharp sand to max depth of 15mm. To level the area use a 2" x 4" wooden bar. Using the bar slide left and right and pull towards you. This gives you a flat even surface. Once complete, using a plasterers float cleanly chamfer the scaplings or sand into the edging system;
Once level use a compactor plate to compact;
Cover the area with a geotex material weed membrane to discourage weed growth. Stretch out taught and nail in position using 4" galvanised nails approx every 0.75 metres. Trim excess to fit;
Unroll the LazyLawn and ensure it’s level (no ripples) and cut into the boundary. If possible it is advisable you run the surface towards the property (i.e. looking into the pile), so when you look out the window of the property, it gives the most natural look;
When fully fixed the whole area should be sand dressed with a high quality kiln dry sand to a maximum weight of 8 kg’s p/sqm;
Installation should only be carried out whilst weather is dry. Should the LazyLawn get wet, this will cause problems when infilling with the sand. Use a stiff brush to apply sand.
How do I use the adhesive and joining tape?
Once groundwork is complete, unroll the two surface that require joining ensuring the pile runs in the same direction on both sections;
Butt the two pieces together, then fold the synthetic grass over on itself by 30cm (12");
Using a straight edge, trim each join edge by approx 3 tufts in ensuring not to cut into the tufts else this will result in a poor seam;
Lay the joining tape through the centre of the join, shiny side down ensuring equal tape under each roll, (nails can be used to hold this in place);
Using a mastik cartridge gun apply a bead of LazyFix artificial grass adhesive, approx 1/2" down the length of the joining edge of the grass. Repeat another bead approx 2" behind this one in a wave pattern. Fold this side of LazyLawn over onto joining tape. Be careful not to trap any of the tufts of grass under the edge of the carpet or contaminate with glue. Repeat this action on opposite side;
To complete the seam, you need 2 operatives. 1st operative needs to glide the synthetic grass in at the start whilst the 2nd operative ensures the grass does not flop over and crush or contaminate the tufts on the opposite side as this will give an imperfect seam;
Once the first section of the carpet has been glided in, the 2 edges need to be brought together ensuring no tufts are damaged or buried. Once complete, check there is a 2-3mm gap between the 2 sections;
Once complete, use a float or a piece of timber to rub over the join to ensure contact. Also place boards or weights along the join;
On larger joins work in small sections (approx 2m - 3m) and follow the same instructions as above.

Permanent installation onto concrete, asphalt and similar surfaces:
Remove all debris and dust;
The concrete should be reasonably smooth and dry, and ideally have a fall to help disperse rainwater. If there is no fall, it's recommended that a few drainage holes are made in the concrete;
It is also a option to use our 12mm Lazy foam or LazyPad under the surface. This helps reduce any imperfections in the sub-floor and also acts as a shock pad;
Fix the surface 100% with a recommended adhesive, LazyFix or Apollo for outdoor. * Please note - it is not always necessary to glue the artificial lawn to the concrete if using a sand filled grass. However we do recommend the perimeters are fixed down;
If fixed 100% we recommend the surface be fully rolled with a carpet roller or similar periodically for an hour for good adhesion. Leave 12 hours before you make use of the new surface.
The surface must be fully rolled for about ½ hour for good adhesion.
It is recommended to sand dress the long pile surfaces whilst dry, with kiln dry sand. Use 6-8 kgs per sqm this will ensure that the pile does not flatten, prolonging the life of the product (outdoor only).
The surface can be double sided taped down or loose laid and kept down with garden furniture or flower pots. Also on ply / mdf areas it may be stapled down. Always ensure that the surface is fixed down adequately to guard against the wind.
Before any work is started, check to ensure that the roof area is waterproof and in good condition. Clean the area with a good brush and clear away dirt;
We always recommend 12mm Lazy Foam or Lazy Pad to be laid over the area. This provides a protective layer for the roof. It is also used to enable the artificial grass to be fixed to the underlay and not the roof surface. Join the underlay system with our blue tape;
(Optional) Fix bull nose trims to perimeters where there are no boundaries. Never run the lawn up the flashings;
Lay the grass applying a small amount of adhesive around the perimeter. Cut the grass into the trims and up to the boundaries;
Sand fill grass with kiln dry sand, (6-8 kg’s p/sqm for landscaping range). This should be carried out whilst weather conditions are dry to allow the sand to filter into the pile. Use a stiff brush to apply.†
* Please note - Artificial grass can only be glued directly onto smooth concrete surfaces. For all other surfaces (i.e. slabs, decking) an underlay is highly recommended.
† These instructions have been written to limit the amount of specialist equipment you would have to hire to complete the job on a DIY level. All LazyLawn installation teams use top quality installation equipment (inc. mechanical brushes etc) to ensure the installation is to the very highest standard.

Roof Gardens and other areas where the Sub-floor area may need to be accessed:
For roof gardens and areas where the sub-floor may need to be accessed for repairs etc, Evergreens recommends that 12mm Lazy Foam or LazyPad is laid first and joined with Blue Tape. Then fix the surface as normal using a recommended adhesive. Once this has cured the surface can be rolled up to repair the sub-floor then rolled back down again.
