**********************************************************************

EVA foam is a soft material.
You can process it easily.
Another name is EVA board, EVA zote, Craft foam etc.
I usually use one called "Lion board".
"Lion board" is sold only in Japan.

Watch video.

**********************************************************************

Use a sharp blade. For example, "Pro Blade".
This is so sharp.
←10枚入り ←50枚入りお得パック

When you cut, put EVA foam on Cutting mat.
Don't cut in the air, while holding by hand.
Break a b blade frequentry, if you feel sharpness of using blade became bad.
If you want to do work more speedy, use "Running fire box cutter","Blade breaker".
"Running fire box cutter" can have 6 pieces blade inside.
"Blade breaker" can break easy and speedy.


Use Art knife PRO for small ornaments etc.

**********************************************************************


Glue with a Liquid super glue.
When you use a Super glue Accelerator, Hardening speed becomes fast.
(Smoke may be generated. Don't breathe in the smoke and don't put in eyes.)


**********************************************************************


Super glue can glue a large surfaces easily.
But it can't glue a small surface such as this photo well


Then you should use a following spray.
I always use this.
Watch video.


Super glue accelerator
This can glue surfaces in several seconds.
When you use 100ml, you can make a armorset or about three weapons.
←100ml ←180ml ←420ml

About super glue
I use general liquid super glue.

How to paint
Begin painting.
At first, paint a undercoat on EVA foam.
The effects are as follows.

-Color becomes well.
-It becomes hard to come off.
-Gloss comes out well.
-You can save quantity of the paint.

There are two methods.
-------------------------------------------------------------------------------------------
1.Gesso
This is easy.

【Merit】
-It's usable just to paint with a paint brush.
-Gesso don't contain thinner, then you can use it in the room.
-You can use also Acrylic paint.
-There are several colors one, white black etc.

【Demerit】
-It's easy to come off than Thinned "Bond G17"(one of liqud glue in Japan).
 Then, use this for weapons and armors without moving parts.
-The gross is smaller than Thinned "Bond G17"(one of liqud glue in Japan).

【Commodities page】
Gesso or Black Gesso
or

【Paint】
Lacquer Spray or Bottle lacquer paint or acrylic paint
or
-------------------------------------------------------------------------------------------
2."Bond G17"(one of liqud glue in Japan)
This is difficult, however it's almighty.

【Merit】
-It'st hard to peel off.
-It can use for PVC pipe or plastic sheets.

【Demerit】
-"Bond G17" is japanese commodity.
 Then you can't get it easily.
 Please use others. For example, you can substitute wood glue for it.
-You must thin it with lacquer thinner.
-It needs thinner, then you must work outdoors.
-It burns easily.
Don't use fire until drying, because "Bond G17" burns easily. Don' use a Lighter etc until drying.
The parts will be charred in seconds.

-for big things -for small things
-------------------------------------------------------------------------------------------
-About paint
I use following paint.


You can use acrylic paint, when you use Gesso.

-------------------------------------------------------------------------------------------

I use "Zoukei be-su" as undercoat this time.
However it's sold only in Japan.
Use Gesso or Thinned "Bond G17"(one of liqud glue in Japan) in substitution for "Zoukei be-su".


Paint "Zoukei be-su" twice with a brush.
Dry it about 2 ~ 6 hours.


Paint black as undercoat color with Lacquer Spray.


Paint gray as undercoat color with Lacquer Spray.


Process Masking tape.
Stick Masking tape on a Cutting mat.



Mark the foarm with a pen and the Templates.
Cut out with a Box cutter.


Stick Masking tape on the point you don't want to paint.


Paint silver with Lacquer Spray.


Paint red with Lacquer Spray.


Paint silver Bottle lacquer paint with a paint brush.


Paint silver Bottle lacquer paint with a paint brush.


When you paint Bottle lacquer paint, use a paintbrush,silicon cup(Use as a paint plate. It can easy to peel paints after dry.),
panint stick, thinner.


Actually, I used a Airbrush too.
If you want to make light and shade, use it.
About Airbrush is here.
