First thing you need to do is get your mix right, if using a render type mix it should be PLASTERING SAND 3-1-1 (sand, cement & lime) with added waterproofer. Note: sharp sand is too dense! Mix to the consistency of thick soup OR follow the instructions supplied with your bagged Tyrolean product. You can also use white sand and/or snowcrete cement, lime and/or waterproofer. Make a mix in a large bucket to top up your gun noting the volumes of materials used (use a measure) to achieve consistency. Always keep your mix stirred each time you top your gun up VERY IMPORTANT.
Set the flicker bar to about middle on your gun adjustment on the comb.
Pour the mix into the machine and hold the machine square to the wall stand back about 2 foot, and turn the handle firstly on low splatter till you get a feel for it. Work from top left to right and then down and back to the left again, keep doing this until finished. It's not hard to do but you need to keep a nice steady pace going in order to stop any build-up. Best thing is to practise on a piece of ply or plasterboard before attempting the main work.
Move your body with the machine and don�t angle it away from the wall, move with it and keep it facing the wall square on, if you angle the machine from the wall the texture pattern will change, likewise if you increase the speed the pattern will change, if you change the mix it i.e. (wetter or drier) the pattern will change, it must be applied consistently. Do the whole area in one go don�t work to dry edges.
When each coat has steadied up a bit, repeat the process again and again, until you have the desired finish. DON�T OVERLOAD EACH COAT. You can always put more on but if you overload it will run and you will ruin the job. Move in a nice steady movement keeping the applicator at right angles and about 250mm from the work. KEEP THE GUN MOVING.
