Contact between elastic sealants and bituminous substrates must be avoided in order to preclude staining and incompatibilities e.g. by such measures as sealing off with OTTOSEAL® A 250 (refer to technical data sheet of OTTOSEAL® A 250).
We recommend using OTTOSEAL® S 18 for swimming pool liners (PVC) or, for natural stone applications, OTTOSEAL® S 70 or S 140 which are compatible with natural stone. The swimming pool liner must be treated with OTTO Primer 1217 beforehand.

(Recommandations on the use of primers -> see primer table of respective technical data sheet)
The adhesive surfaces of the sanitary acrylic must be pre-treated with Cleanprimer 1101 to achieve an optimal adhesion.
Potential maintenance joints are, for example, joints that are exposed to strong chemical and/or physical influences or constant wet exposure and/or are regularly treated with high-pressure cleaners.
These include joints in sanitary areas, large kitchens, swimming pools, in industrial areas as well as floor joints subject to heavy wear.
An elastic (silicone) joint in private and professional/public sanitary areas should be checked at regular intervals to avoid consequential damage.
Any damage found to the (silicone) joint on the sealant used must be repaired immediately to avoid consequential damage to the structure and/or the fabric of the building. Professional renewal is required to remove this damage.
You can find tips for professional joint remediation in the guide entitled Perfect mould prevention & remediation.
Without external influences OTTO silicone sealants show no stains. External influences which might cause staining are, for example,
Paint-compatible sealants are sealants that can be used to seal building components coated with paint without harmful interactions occurring between the sealant and the paint and adjacent building materials. This also applies in the same way to a subsequent painting of the components, where the paint on the sealant must be limited to 1 mm in the edge area of the joint. For example, paint-compatible sealant (e.g. OTTOSEAL® S 110 or OTTOSEAL® S 120) can be subsequently applied to the joint surface at up to 1 mm in the frame edge area and the glass retaining strip when sealing the glass rebate on a wooden window.
Sealants that can also be coated over the entire surface are paintable. The information in the applicable technical data sheet, in particular on the suitable painting systems, must be observed.
Silicone sealants react with humidity in the air and cross-link from the outside and inside. Complete cross-linking is completed after about 5 to 8 days (+ 23 °C / 50 % relative humidity) at a joint depth (sealant thickness) of about 6-7 mm in an indoor climate. Lower temperatures and/or humidity will extend the hardening time.
Showers, washbasins, bath tubs etc. which have been sealed with, for example, OTTOSEAL® S 100 or OTTOSEAL® S 105 can be put back into service after 1 to 3 days.
OTTOSEAL® S 100 and OTTOSEAL® S 105 are immediately water resistant: however, no mechanical stress must be put on them during the curing period for at least 1 or 2 days by means of cleaning or weight loads (expansion and compression of the joint)
Primers are adhesion agents which improve the adhesion of the sealant on porous or problematic substrates. The primer leaves a film or residual adhesion agent on the substrate on which the sealant has a better adhesion.
Substrates must be dry, neat and clean during the priming process. Apply primers sparingly to non-absorbent substrates and apply generously to absorbent substrates. Please see the technical data sheet and priming table!
Transportation and storage of anhydrous adhesives and sealants based on silicon, hybrid and polyurethane are possible for a limited period. Permanent storage at temperatures below 0°C is not recommended, particularly because processing of "cold" sealants leads to longer curing times and most products are of a harder consistency at low temperatures, as is the case when they are taken from cold storage and processed immediately. “Cold” products should be warmed to room temperature prior to processing.
After complete curing these products are permanently resistant to temperatures below 0°C.
During processing care should be taken that there is no ice, dew, condensation water or any other source of dampness on the seal surfaces, as this functions as a release agent and impairs or prevents bonding of the sealant.
Aqueous adhesives and sealants based on acrylic dispersions, as well as OTTOCOLL® A 270 and the aqueous OTTOFLEX products, are not resistant to frost when unprocessed and during the curing phase and should not be stored or processed at a temperature below + 5°C Some acrylic dispersions are resistant for a limited period and can be transported at -10°C for a maximum of 48 hours. In this context the information provided in the latest technical sheets should be referred to. Longer storage or storage/transportation at lower temperatures causes irreversible frost damage to the acrylic sealant (coagulation).
After complete curing most acrylic dispersions are permanently resistant even at temperatures below + 5°C.
For bonding staircases, we recommend using OTTOCOLL® P 85 or OTTOCOLL® Rapid (force-locked indoors) or OTTOCOLL® M 500, M 501, M 530 HiSpeed, or M 550 HiTack (stress-compensating, indoors and outdoors).
Primers are bonding agents which improve the adhesion of the adhesive to porous or problematic substrates. The primer leaves a film or residual bonding agent on the substrate on which the adhesive can build up better adhesion.
Substrates must be dry and clean when priming. Primer must be applied sparingly to non-absorbent substrates and generously to absorbent substrates. Observe the technical data sheet and priming table!

Yes, OTTOSEAL® S 100 is suitable for exterior use and boasts very good weathering, ageing and UV resistance.
In bonding processes and bonding techniques, the open time is the permissible period of time from the beginning of the application of the bonding agent to the joining of the parts to be bonded. This can be influenced by heat, draughts, absorbent substrates and sunlight, among other things.
At low temperatures, there is a risk of condensation forming a thin, invisible layer of ice or water on the substrates. This separating layer prevents optimal adhesion of the sealants to the substrate.
Single-component hybrid, PU and silicone products require ambient humidity to harden which is virtually non-existent at low temperatures below + 5 °C. Water-based sealants such as dispersion acrylates are sensitive to frost when fresh and must not be processed at temperatures below + 5 °C.
Matte and matte-sanded sealants and textured surfaces: When smoothing matte, matte-sanded and textured OTTO sealants, please observe the following: The joints should only be tooled once with a smoothing tool, which was dipped in OTTO smoothing agent. The more often the surface is reworked with smoothing agent, the more the matte effect is lost and the joint becomes glossier. When smoothing matte sanded shades with the matching OTTO smoothing agent, it is not recommended to smooth the joint with a finger, as this presses the sand particles into the sealant and they are no longer visible on the surface. For this application, we therefore recommend our OTTO smoothing tools as the perfect addition.
Yes, all silicone sealants from OTTO have excellent UV and weather resistance.
Anhydrous bonding agents and sealants based on silicone, hybrid and polyurethane can be temporarily transported and stored at below-zero temperatures. Permanent storage at temperatures below 0 °C is not recommended, especially because processing of the "cold" bonding agents and sealants results in delayed hardening and most products have a firmer processing consistency at cold temperatures when they are removed from cold storage and then processed immediately. "Cold" products should be brought to room temperature before processing. After complete hardening, the processed products are permanently resistant even in the long term below 0 °C.
When working in cold temperatures, it is essential to ensure that no ice, condensation or other moisture is present on the flanks of the bonding agent, as this acts as a separating film and can impair or prevent adhesion of the bonding agent.
Water-based dispersion sealants and bonding agents, as well as water-based OTTOFLEX products, are not frost-resistant in their unprocessed state and must not be stored or at temperatures below + 5 °C while they are hardening. For a short time, some dispersion acrylates are resistant during transport to temperatures down to - 10 °C for a maximum of 48 hours. The information provided in the relevant current technical sheet must be observed for this. Prolonged storage or storage/transport at lower temperatures leads to irreversible frost damage of acrylate sealants and bonding agents (coagulation).
After complete hardening, dispersion acrylates are permanently resistant even below + 5 °C.
A joint affected by mould must always be remediated, as there is a risk of damage to the building fabric. Detailed information on this can be found at otto-anti-mould.com.
