Acryl 15

Acryl 15 is a single-component rapid surface-filming sealant based on acrylic polymers dispersed in a water base. When the product is applied, the water base evaporates leaving a hardened flexible plastic mass with excellent resistance to ageing. Acryl 15 Fast also adheres on damp substrates. It is easy to apply, does not drip and can be smoothed off quickly. The tools used for application can be washed with water. It is ideal for sealing indoor and outdoor joints with a maximum expansion of 15%. On outside surfaces Acryl 15 Fast is recommended for joints on vertical or horizontal surfaces, in all cases where water cannot collect. Acryl 15 Fast is classified as a non-structural sealant for components utilised for both internal and external facades (F-EXT/INT) in compliance with EN 15651-1.

Instructions for use

1. The sides of the joint must be solid, clean and grease-free. Acryl 15 does not require primer. With porous substrates and in the hot season we recommend dampening the surfaces. In the case of critical surfaces, to improve adhesion, it can be advantageous to apply, using a brush, a bottom coat obtained by diluting one part of sealant in 10 parts of water. Deep expansion joints must be plugged with suitable pre-forms before sealing.
2. Insert the cartridge (or bag) in the mechanical or pneumatic dispenser gun and extrude the sealant, using nozzles of a diameter that is proportional to the width of the joint.
3. Extrude an abundant quantity of sealant in the joint cavity.
4. Smooth before the surface filming has started, by applying pressure on the material to completely fill, leaving no gaps and with complete adhesion of the sealant to the sides of the joint.

Storage

Acryl 15 stored in the original packaging and at a temperature between +5 and + 25, the product will keep for at least 24 months. Partly used cartridges can be stored for approx. 3 months provided they are tightly closed. Protect from frost.

Warnings

The hardening of the material takes place by evaporation of water: the sealant will lose its initial tackiness within 20 to 120 minutes depending on ambient conditions. Low temperatures and high relative humidity will slow down hardening. High temperatures and low relative humidity will accelerate hardening. Do not apply Acryl 15 when rain is forecast: once applied but not yet filmed the sealant is liable to be washed away. Sealant which has not completely hardened will be damaged by frost.
