Application and Removal of Prime Retarder.
4.1 We suggest you use a quality pressure back pack spray unit to ensure that you have enough capacity to cover the whole area in one application to achieve the best possible finish.
4.2 Because Prime Retarder is coloured a bright fluorescent green you will be able to easily see and gauge the consistency of surface coverage ensuring no surface has been missed.
4.3 When the conditions are just perfect you will see what we call a ⤽PITA PATA⤝ effect form on the surface of the concrete as the Prime Retarder is being applied. When you see this surface effect you’ll know that you are achieving perfect surface penetration. NB. During warmer months, we recommend that you cover all sprayed surfaces with polythene builders film once Prime Retarder has been applied. This will greatly reduce wash off times.
4.4 Don’t worry about over-spray. Because Prime Retarder is water based it will wash off any surface with ease later when you commence the wash off stage.
Step 5: Dependent on weather conditions wait from 12 to 24 hours before you commence the wash off stage of Prime Retarder.
5.1: We suggest you use a high pressure water spraying unit, with 3 – 4000psi and a stiff broom to remove excess slurry.
5.2: Cover all drains, pits and gutters with double folded hessian, or similar material to ensure no residue mortar sets and obstructs drainage.
