Wessex System 200 solvented epoxy: Mixing and application

Mixing instructions

Mix the resin and hardener to the specified proportions - 2 parts by volume of resin : 1 part by volume of hardener. Stir well until a homogenous mix is obtained and allow to stand for 15 minutes before using.


This epoxy sealer can be applied with brush, roller or spray. When spraying, reduce viscosity of the composition with up to 20% Wessex 200 thinners, dependent upon the type of gun being used. Apply subsequent coats within 24 hours of previous application. Do not apply this epoxy system below 5°C. Clean brushes and all tools with Wessex 200 thinners immediately after use.

Wessex System 200 covers approximately 9m² per litre of mix. Two or four coats are considered adequate. It is essential to prepare the surfaces before application of the varnish and they must be sanded, free from oil and grease and all other contaminants and moisture.


Wessex System 200 contains flammable solvents and due precautions must be taken against all means of ignition. Avoid inhaling vapours which are harmful when taken internally. Please refer to relevant Material Safety Data Sheets before using.

All epoxy systems separately or after mixing are capable of irritating the unprotected skin and in extreme cases dermatitis may be caused. To avoid this wear suitable chemically resistant gloves.

Other protective clothing of the right type should be worn by workers repeatedly handling epoxide resins and hardeners. Workers should maintain the highest standards of personal cleanliness, removing any resin or hardener from the skin as soon as possible and certainly before the hardening process has made it insoluble. This should be done with WEST SYSTEM Resin Removing Cream or a similar material and frequent washing with soap and water and drying with disposable paper towels.
