Everbuild 201 Admix Mortar characteristics and advantages
Conforms to BSEN934- Part 3 (2009).
Extra tests were carried out in over and above those required by BS4887, to simulate more effectively actual performance requirements in site conditions. One such comparative test is shown below, which simulates the actual loss of air form a mortar mix due to vibration when transferred to site.
Freezing Point | -100C |
Usage | Using at an addition rate of 125 - 250cm3 per 50kg cement |
Vol Air Entrained | 14 - 20% |
Loss After 1 Hr Standing | Not reduced by more than 3% from vol. air entrained |
Loss After Extra 15 Mins Mixing | Not reduced by more than 5% from vol. air entrained |

APPLICATION INSTRUCTIONS
Mixing
In all cases, add to mix at an addition rate of 150ml to 250ml per 50kg cement, depending on the degree of plasticising/entrainment required. Note: remember to reduce required quantity of water accordingly. One litre of EVERBUILD® 201 Mortar Admix added to a 200ltr drum of gauging water will be sufficient for gauging approx. 4 x 50kg cement for mortar or render mixes. Whilst overdosing should be avoided, this formulation does safeguard against moderate overdosing. (up to double the maximum rate).
The following are examples of modified mix designs.
1: 0.25:3 cement: lime : sand
use 1: 3 cement : sand + EVERBUILD® 201 Mortar Admix
1:1:6 cement : lime : sand.
use 1: 6 cement : sand + EVERBUILD® 201 Mortar Admix
BRICKLAYING/POINTING: Use a mix design appropriate to brick strength (1 : 3 to 1: 6).
INTERNAL RENDERS:1 : 6 + EVERBUILD® 201 Mortar Admix
EXTERNAL RENDERS: 1 :3 + EVERBUILD® 201 Mortar Admix
LIMITATIONS
- Do not use in structural concrete.
- Do not overdose.
- Do not mix with other additives in same gauging water.
- Do not use in lime based mixes.
