CALSTRIP
Surface-Retarding Form Release Agent - To expose aggregate and to produce a keyed surface for subsequent rendering or abutting concrete pours.
EFFECTS: |
Calstrip forms a tough, semi-glazed coating on formwork, which very slowly dissolves in the concrete surface to prevent set. On striking of forms, the retarded surface mortar is brushed or hosed off to leave a roughened or aggregate exposed finish. Does not stain render. Fully compatible with other Cementaid products. Calstrip is a safety product and will not reduce the strengths of cement exposed to it, once the retarder effect has worn off. |
NOTE: |
The concrete should be placed against the treated form in such a way as to prevent premature removal of the Calstrip by abrasion. |
WHERE RECOMMENDED: |
As release agent for all concrete formwork where either an exposed aggregate finish or a roughened surface is required. For horizontal exposed aggregate paving work, spray Calstrip at the rate of 4-6 square metres per litre on to the freshly screeded surface to be exposed, (depending on depth of exposure required) and cover with dense plastic sheet until immediately ready to hose-off with low pressure water spray, to expose aggregate. For architectural / exposed aggregate work, trials are recommended to determine optimum application rate and technique to achieve required finish |
|
SPECIFICATIONS |
| All formwork shall be treated with one liberal coat of Calstrip stripping and keying agent, applied at least four hours before pouring concrete, allowing minimum one litre per 6 square metres, or reduce coverage for deeper exposure. The form surface(s) may be treated up to one week before pouring concrete, but shall be protected from direct sunlight and / or rain by covering with polythene sheeting, taped in place. During removal of the formwork (within 1-14 days), the exposed surface should be immediately scrubbed down with a stiff broom, or hosed with water jets to remove retarded surface material and expose roughened surface for rendering etc. For architectural / exposed aggregate work, trials are recommended to determine optimum application rate and technique to achieve required finish. |
