May 4, 20251 yr Hi new here need some help in mixing cement even though I know how I have had a problem that I've never come across before maybe someone can help. I purchased some blue circle brand cement in plastic packaging not the ready mixed stuff, anyways I did a 4:1 mix with Travis perkins bricklaying sand also plastic bagged however when mixing in a bucket it started to bleed after leaving for a few mins so I mixed it more thinking it's not enough but again it's bleeds even with plasticicer what am I doing wrong.

The relative dampness (or dryness) of the materials (in this case , sand) makes a noticeable difference. Bagged contents might be damper than normal (water is cheap) A paddle mixer might help?
May 4, 20251 yr Helps to get the terminology right! (pet hate of mine, so many people call sand & cement mix "cement", sorry 🙄) Cement is the stuff you mix with sand to get mortar (and sand and stone to get concrete) If it is plastic bagged it shouldn't be too wet? It sounds like you are putting too much water in the mix (assuming you mean that it is running out of the joints when you say bleeding) Ratio of sand to cement does depend on what you are using it for, why have you chosen 1:4 (cement/sand ratio)?
