Step 1 - Choose your Substrate

Cement Board - Durable Smooth and Flat

Live in a war zone or Kids a bit on the wild side, look at Cement Board. Ideal for outdoor cinema screens.
It's harder to cut than other substrates, but the effort will be worth while in the long run. If done correctly your screen will be impervious to weather and damp. You can get various different thicknesses, the thinnest will be sufficient for your projector screen.

Step 2 - Cut to Your Desired Screen Size

Cut Projector Screen Down to Size

Cutting down to screen size is a bit harder with cement board. It can be cut or scored and snapped. We recommend cutting for accuracy.
To do this use a carbide tipped circular saw. Mark out your screen size and cut along the lines. The board is tuff, so ease up big boy, don't force the saw. Don't attempt this if your not confident. We don't want horror movies on this screen yet. Smooth off any rough edges with glass paper.

Step 3 - Surface Preparation

Wipe down surface

Clean Away Dirt and Dust

Clean Away Dirt and Dust

Before painting check the surface for dirt and dust. If necessary brush off and then wipe down with Methylated spirits. It evaporates fast and leaves no residue.
Use a gloss roller

Scream is formulated to lay flat, a gloss roller (the cheapest) will reduce roller marks
Seal with sealer binder

First Seal the surface

First Seal the surface

This is a must do. Naked boards will suck up paint all day long, unless they are sealed. Warning: Do Not paint Scream directly onto naked boards. First seal the substrate with a good water based sealer binder. Cement board outdoors will need to be sealed all over. This can be done with the sealer binder or a water based Penetrating sealer that can be painted over. The screen surface should only require two coats, even if you use a penetrating sealer. Coat and leave the required time to dry, as stipulated by the manufacturer.
Add additional coats until the board is a solid white with no patches - this is Important Try not to over load the roller. It should rotate freely rather than skid over the surface. Unhurried vertical strokes will avoid 'splatter' and should be finished off with a single vertical roll in one direction from the top of the screen to the bottom - for every coat.

Step 4 - Top Coat with Screen Paint

mix scream well

Finally Paint Your Screen

Paint Mix your screen top coat well, mix your paint well start with a good shake and a stir. If it isn't mixed right it wont work right.
Using a new roller use the same technique as before. Imagine the surface divided into stripes and work systematically left to right over the whole area. The aim is to apply the paint evenly and always work from a 'wet' edge. The edges need to be blended in to avoid leaving a ridge of paint. Ideally try to roller at a cool part of the day, this will give you more time. On cool days you will be able to roller the whole surface left to right before the paint begins to dry. On hotter days divide the screen in to narrower sections and complete each section as above.
On a sealed surface Scream will cover approximately 16m²/L
