BOSTIK H550 flexible adhesive sealant

SEAL'N'BOND ALL-IN-ONE H550 is a universal, one-component, hybrid adhesive-sealant for general construction and industrial applications.

Capacity : 290ml

For internal and external applications, including for indirect contact with food and in wet rooms, as well as for floor and facade expansion joints.


  • Permanently flexible in a wide range of temperatures and changing weather conditions
  • After hardening, it can be effectively and conveniently painted without scratches, cracks and discoloration
  • Does not contain isocyanates, silicone or solvents
  • High mechanical resistance
  • High deformation capacity ± 25%
  • It compensates well for vibrations


Very good adhesion to most materials without priming, e.g. concrete, stone, terrazzo, fiber-cement, plasters, screeds, construction ceramics, varnished or impregnated wood, MDF, HDF, cork, plywood, chipboard, enamelled steel, stainless steel, aluminum, zinc, copper, lead, tiles, terracotta, stoneware, glass, glass, sanitary ceramics, porcelain, PVC, PU, ​​HPL and similar types of plastics.


100 ml / 1 meter of grout with a cross-section of 10 mm x 10 mm = 100 mm².

By multiplying the joint width (mm) by the joint depth (mm) we obtain the number of milliliters / 1 running meter.


  • Bonding various building materials and finishing elements (insulating materials, window sills, wall decorations, thresholds, finishing strips, masking strips, plinths, wall panels, furniture joinery, etc.
  • General construction and industrial seals, facade and floor expansion joints (pedestrian routes, sidewalks, warehouse floors, ramps, maneuvering areas, parking lots, vehicular traffic, etc.)
  • Refrigeration equipment, containers, auto-refrigeration plants, sandwich panels, food industry plants
  • Sealing roof joints
  • Sealing window/door-wall joints (wooden, metal and PVC joinery)
  • Flexible seals of steel structures (halls, warehouses, shelters, silos, containers, tanks and similar structures)
  • Corner seals in ceramic tiles (terraces, balconies)



The substrate must be dry, clean and degreased. Before using on plastic substrates or paint coatings, it is recommended to perform an adhesion test. For joints with porous or absorbent surfaces, use Bostik Universal Primer T300. After priming, wait at least 15 minutes (max. 4 hours) before applying the mass.

Concrete must be completely hardened and seasoned. Sealed floors, screeds, subfloors and other similar surfaces must be insulated against the negative effects of water. If necessary, first fill the gaps with foam expansion cord. Place the rope carefully in the slot to the required depth so as not to damage it. In the case of shallow slots where there is no room for the string, to avoid three-sided contact, cover the bottom of the slot with PE tape. The edges of the gap can be protected with masking tape to avoid contamination. The tape should be torn off immediately after applying the mass and shaping its surface. Use Bostik Finishing Soap T500 to smooth the grout surface. The grout should have a shape that allows water to flow freely.


In case of uses of the product as an adhesive : apply in parallel vertical strips at small intervals (10-20 cm - depending on the size of the glued elements). Do not apply in spots. Support heavy elements or otherwise secure them against movement until initial hardening. For this purpose, you can use 3 mm thick double-sided adhesive tape, which will additionally ensure the proper thickness of the glue joint and ventilation between the glued surfaces.

In case of product use as a sealant: Apply the mass slowly, carefully filling the entire cross-section of the gap, so as not to trap air in it. Shape the surface of the mass with a spatula and smooth it out within 10 minutes of application. The rate of hardening of the product depends on the ambient temperature and air humidity. As the temperature and humidity level increase, the polymerization process proceeds faster. Additionally, the hardening time depends on the cross-section of the joint. Ensure effective ventilation until the grout is fully hardened.


Fresh dirt can be removed with Bostik Universal Cleaner T100. Hardened material can only be removed mechanically. To clean your hands, use special Bostik Cleaning Wipes T150 cleaning cloths.
