## Overview

SP201 Acrylic Polymer is a premium 1kg additive designed to strengthen plaster casts by increasing density and flexibility while providing waterproofing and enhanced color vibrancy. Its low-fume, ammonia-free formula ensures safe use in enclosed spaces, making it ideal for artists and professionals seeking durable, visually striking, and moisture-resistant plaster creations.

## Description

SP201 Acrylic Polymer is a high-performance additive used to enhance the properties of plaster casts. When mixed with plaster, SP201 improves flexibility, adherence, and overall durability, making it an excellent choice for both artistic and industrial applications. This acrylic polymer enhances the surface hardness and provides resistance to chipping and cracking, prolonging the lifespan of the plaster casts.Additionally, SP201 Acrylic Polymer increases water resistance, making the casts suitable for outdoor or high-moisture environments. Its compatibility with various pigments allows for vibrant coloration without compromising the integrity of the plaster. Easy to incorporate into standard plaster mixing processes, SP201 ensures a consistent and smooth finish ideal for detailed work. Users benefit from its versatility, allowing for creative and functional uses in sculptures, architectural elements, and decorative pieces.Instructions.The product needs to be diluted, typically 1 part polymer to 4 parts water as a strengthener, and 1 part polymer to 5 parts water to give casts a water resistance. How much you require depends on use but as a rough guide a 250ml bottle would treat between 2kg of plaster. *Note when using the polymer less water is required as it lowers the surface tension enabling a denser cast. It is possible when striving for that perfect cast (such as when making chess pieces) to double or even treble the quantities used.

Review: Used for artisinal vases - Acrylic polymer I use to make vases
Review: Used as a Heavy Waterproof Sealant on Filler - I actually used this on filler around my window, where the plaster had come away from being damp. It worked a treat and here we are a year later and filler and paint it still looks as good as new and is very strong and sound.
