Review: Get more gloves and double pot the mix! - Bought this kit for small epoxy job. West system is a well known brand with excellent products. Needed to seal the edge of a door which was chipboard interior for an odd sized frame. Hard as nails when fully dried. Kit has everything you need for small repairs or sealing surfaces. Read instructions particularly on temperature. Can be slow to dry if colder than recommended. Good value if you just want for one off job. Review: Very good stuff. If you haven't used epoxy before read ... - Very good stuff. If you haven't used epoxy before read the instructions and watch a few videos before you start doing any work. When you think you know what your doing read the instructions again to make sure. This stuff hardens very quickly so you don't get much time to make any adjustments once you start applying your mix. You will defiantly need to ware the gloves as each of the components on their own are very sticky and time spent peeling it off your hands is less time mixing and fixing. ## Features - Causes serious eye damage. - Causes serious eye irritation. - Causes severe skin burns and eye damage. - Causes skin irritation. - Harmful if swallowed. - Harmful in contact with skin. - Harmful to aquatic life with long lasting effects. - May cause an allergic skin reaction. - Suspected of causing genetic defects. - Toxic to aquatic life with long lasting effects. - Maximum Strength & Durability: This heavy duty clear epoxy resin is perfect for indoor & outdoor DIY projects, providing a marine grade level of adhesive strength.
