Preparation of the Surface
Fresh foam adheres to all commonly applied min-eral building materials, including insulation materi-als such as: EPS, XPS, mineral wool, etc. Every surface must be compact, smooth, load-bearing, dry, clean and without any film (grease, dirt, dust, oil, lubricant, etc.) which would reduce adhesive-ness. The foam does not adhere to non-mineral surfaces such as: silicone, polyethylene, some other plastics, etc. Before application the surface must be well moistened with water. Foam may be applied in a temperature of between +5°C and +30°C. Hardened foam is semi-rigid and forms a structure of enclosed cells. It is resistant to temper-atures of between -50°C and +90°C and to ageing processes, except UV radiation. After hardening, it can be cut, ground, sanded, painted or plastered.
Implementation
Before use, cold containers must be carefully warmed in tepid water. Do not heat containers to a temperature above +50°C, because of the risk of explosion. Heated containers (e.g. left in vehicles in summertime), must be cooled down in water. Whilst cooling, containers may be shaken from time to time in order to reach the required temperature of the product more quickly;
- Before application, the temperature of the can and its content must be between +5°C and +30°C (optimum application temperature: approx.: +20°C);
- Shake the can vigorously for about 30 seconds. Additionally, shake from time to time during application;
- Screw the attached applicator onto the can.
- Do not unscrew the applicator before the can is completely empty;
- After opening (i.e. screwing on the applicator), use the foam as quick as possible otherwise the foam will be hardening on the valve and in the application pipe preventing complete emptying of the can.
- Moisten the surfaces on which the adhesive is to be applied but do not make them wet. Equal and quick hardening of the foam requires moisture. Inappropriate moistening or overflowing of the joint and of the openings may lead to uncontrolled expansion of foam volume;
- Hold the can in a bottom-up position during application;
- Fresh foam expands between 1.5 and 2 times, so be careful not to fill the joint too much (openings should be filled to approx. 60%). Remove any excess or fresh foam immediately using a cleaner. If this is difficult or impossible, leave the foam until it hardens and then remove mechanically.
- Clean the application pipe and surfaces smudged with foam using cleaners for polyurethane foams, e.g TO-CDA cleaner. Cleaning is possible until the foam hardens completely. Hardened foam can only be removed mechanically.
Caution
