  • Smooth finish of A1

There are 3 main used techniques to finish A1 smooth:

A1 Thix A
Add A1 Thix A to the A1 to thicken the A1 into a paste. Apply the thickened A1 paste with a spatula or putty tool. This creates a layer that you can finish within 1 hour with a slightly damp sponge for a smooth result. After drying you can work on the A1 object with (waterproof) abrasive pads or (waterproof) sandpaper.

A1 ATP Powder
A1 ATP Powder is a volume thickener. This allows the A1 to be thickened to filler thickness. Thicken the A1 with ATP Powder; with this A1 can be thickened to filler thickness. The ATP Powder can be added indefinitely, until the desired thickness is reached. This does, however, result in a less strong product when a large amount of ATP Powder is added. ATP Powder can only be used for indoor applications.
The application of A1 with ATP Powder goes well with for example spatula, palette, putty knife etc.

After drying you can if desired with waterproof abrasive pads or waterproof sandpaper further refine to an even smoother whole.

C-veil
C-veil is a thin glass fleece finish. Apply C-veil to the still damp last layer A1. If the A1 is dry, first coat it with a layer of A1. The C-veil is very easy to tear, small pieces are easy to press, so you can achieve a nice smooth and seamless result. If desired, a second layer with C-veil can be applied. Like the A1 Triaxial fibre, the C-veil cannot be sanded.

Smooth finish with Thix A using a brush, roller, spatula, squeegee, sponge, sanding paper or machine

Creating a smooth finish on the object. First weigh 1 part A1 Liquid and 2 parts A1 Powder.
Add 2% Thix A (of the total quantity A1) to the A1 Liquid. By using Thix A the A1 will result in a thicker texture.
Mix the A1 Liquid, Thix A and A1 Powder resulting in a smooth material.
The A1 can be applied with a: brush, roller, spatula or squeegee.
Result is a smooth finish.
Or use (after ±20 minutes) a damp sponge or a waterproof sanding pad.
Or by using sanding paper manually or by machine.
Resulting in an even more smooth finish.

Smooth finish with C-veil

Creating a smooth finish on the object. First weigh 1 part A1 Liquid and 2 parts A1 Powder and mix until all lumps have disappeared.
Tear off a piece of C-veil (use gloves).
Apply a thin layer of A1 on the surface.
Press the small pieces of C-veil into the A1. Overlay the pieces of C-veil.
The C-veil must be covered with a layer of A1 by hand or brush.
For a more smooth finish you can add a second layer of C-veil.

Smooth finish with C-veil

Creating a smooth finish on the object. First weigh 1 part A1 Liquid and 2 parts A1 Powder and mix until all lumps have disappeared.
Add as much ATP powder as needed into the A1. Stir firmly till all lumps have disappeared.The A1 texture can be made as a paste or as a putty.
Resulting in a smooth finish. For an even more smooth finish (after ± 20 min.) use the sanding techniques.
