AccouStick 4in1 is a builders materials that provides superior acoustic dampening properties in a single application that achieves acoustic dampening without having to apply an additional layer of rubber mating. Step around improvement measure up to 17db depending on type of timber flooring and substrate. Accou-Stick is an elastic one part, non-hazardous, solvent free, MS polymer adhesive. Accou-Stick is a acoustic timber flooring adhesive suitable for bonding all floor types such as parquetry, solid, engineered on concrete slabs, plywood, particleboard, existing timber flooring and underfloor heating.
Advantages for user and environment
- Free of isocyanates, solvents, formaldehyde, halogens and silicone
- Simple cleaning of parquet and tools after application. Non staining.
- For the most part no need to use primers or similar products containing solvents
- Persistent impact noise reduction due to permanent elasticity
- Step sound improvement measure up to 17dB depending on type of timber
- May eliminate the need for acoustic underlays depending on type of floor, its thickness and the type of timber used
- Non Slump, easy spread formula
- Contains no water and will not cause pouring of the wood after installation
- Very low odour
- Low VOC emissions being compliant with Green Building Council of Australia Building v1.0 Exposure to Toxins credit
- Ready to use, no mixing, high green strength
- Cures without shrinkage
- Is very long-lasting. This minimizes the need for repair and saves resources
- Available in 16kg pails
Handling advantages
- Optimal viscosity allows high efficiency in laying parquet
- Long tooling time
- Tolerates varying temperature conditions and high residual humidity of the floor.
- This decreases preparation and waiting time before the actual parquet laying process
- Excellent thixotropy. Can be applied by various tools (e.g. spatulas) Uneven floors can be smoothed by applying the adhesive a second time
- Compatible with many possible floor materials. Also cures properly on non-absorbing floors
- Not sensitive to slight movements during curing phase
- Walking on the parquet is possible at an early stage
- No unwanted fast boundary curing on floors with high residual humidity (as seen with many PUs)
- 1-component application directly from bucket . No need to mix or modify prior to application
- Suitable for underfloor heating
Application recommendation
- The application should be done all-over (holohedral) using a tooth spatula.
- We recommend using a toothing according to TKB B3 with a tooth depth of minimum 3.0 mm.
- Bear in mind not to exceed the open time of the adhesive.
- Voids or insufficiently applied adhesive can cause a reduction of the impact sound insulation.
- The parquet has to lie evenly in the adhesive bed.
The parquet must not be in direct contact anywhere with the building structure (walls, super structural parts, heater devices, pipes etc.). The distance of the parquet to those parts of structure should be adjusted so that even if it expands due to higher moisture or temperature there is no direct contact. Direct contact causes increased sound transmission. Keep distance to wall. If the parquet does not lie flat, apply weight over night.
