The powdered setting compound chemically hardens when mixed with water. In order to be environmentally friendly, make sure that your purchase does not contain preservatives, volatile organic compounds (VOCs), mildewcides and fungicides. The binders used should be natural and the fillers must be inert. Some joint compounds are also known to create allergies. Ensure that your compound is hypo-allergenic also. Once you get such a ready-mix or setting-type compound, you are ready to begin.

    d. Once you obtain the right consistency, the compound is ready to use. In case you want to store it, scrape along the sides of the compound bucket to level. Then, cover with a wet rag on the surface and create a thin water-layer above it. Place a plastic wrap and seal the bucket securely with the lid. This will prevent the compound from drying out.

    b. According to the instructions on the bag, take the required quantity of water in a second bucket. Always add the powder to the water and not the other way round. Otherwise, you will not get the uniform consistency. Shake the powder at first. Then mix thoroughly.

    c. After mixing the powder thoroughly, wait for the time specified on the bag. This can very between 10 to 20 minutes. Keep adding a little water and mixing to maintain the smoothness and consistency.

Things to look out for

  • The compounds available in the market have set-times varying from 5 to 210 minutes. The time specified on the bag is an average figure which will can change depending on temperature and humidity.
  • While cleaning up the setting-type compounds, never flush down the drain. They will block the drainage and it becomes very difficult to clear the clog.
  • Do not add too much water to the ready-mix. If it gets soupy in thickness then it becomes very difficult to use it successfully.
  • Do not try to estimate or eyeball the amount of compound to be taken out of the sack. Weighing the setting-type compound is always the safe option.
  • Do not mix too much or too fast when it comes to the setting-type compound. This will hasten the set-times of the compound.
