Cement Board - Durable Smooth and Flat
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
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
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.

Scream is formulated to lay flat, a gloss roller (the cheapest) will reduce roller marks
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
Finally Paint Your Screen
Mix Well and Top Coat 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
