Most are 2 day classes offered in the industry at present. I am cutting that in half. Your sentence is an over simplification as there is more than meets the eye esp to someone new at encap. Learning how to encap, how to ID commercial carpet as Olefin, polyester or nylon, proper spotting techniques, proper chemistry for different soil levels, how to sell commercial cleaning, how to clean stairs, furniture and residential carpets with encap and how to handle urine with VLM without using HWE takes time to explain and show with various equipment on the market. Using a CRB, planetary, rotary or oscillating pad takes time and skill also.Does it really take a full day to teach a cleaner how to encap? If so, they are doomed to fail.
