There are two main methods of fixing
MouseMesh airbrick grills:
1) Glue Mouse Mesh with mastic adhesive
- use a cartridge type exterior glue available in most DIY shops
- brush off or wash away any dirt, moss or loose brick and allow to dry
- do not remove hole covers at corners of Mouse Mesh frame
- apply a continuous bead of adhesive, about 6mm in diameter, around the back edge of the frame - you will need a glue gun to apply the adhesive - these are readily obtained from DIY shops and stores.
- gentle push the frame into place ensuring that the glue is sufficient to bond to the brick around the whole edge - make sure that you place the Mousemesh the right way up - the text
DO NOT BLOCK THIS VENTILATOR should be readable at the bottom
left of the Mousemesh when in place.
- leave Mouse Mesh grill undisturbed whilst glue cures - 24 hours will usually give a cure depth of about 1.5mm
Glue coverage: One standard cartridge of adhesive should be sufficient for approximately:
- 12 small Mouse Mesh grills
- 10 medium Mouse Mesh grills
- 8 large Mouse Mesh grills
2) Screwing the Mouse Mesh into place
- Please note that our ABS range does not come with screws
- use four brass or stainless steel round head screws approximately gauge 6 by 1.5 inches - but please check head size as manufacturers sizes may vary. Alternatively use No 4 gauge.
- remove screw caps at corners of Mouse Mesh by pushing from the back with a small screw driver
- mark through holes onto brickwork
- drill out holes with masonry drill
- push plastic raw plugs into holes flush with surface of walls
- attach Mouse Mesh applying reasonable pressure to screws but avoiding over tightening which may damage the grill
- push screw caps back into place
Mousemesh grilles must not be used to cover air vents which are being used for
the ventilation of gas appliances. The mesh may become blocked with dust, leaves, dirt etc which would restrict or even block air flow and increase the risk of the carbon monoxide poisoning.
