Technical Data Sheets

Product FAQs

Will this kill garden plants close to the wall?

If used as instructed no. However please be careful, accidental overspray onto plants can scorch foliage but should not kill your plants. If plants are in the vicinity, before applying GK CFW, we recommend watering well and covering with a waterproof fleece. If you notice an accidental overspray during treatment rinse of thoroughly with water.

What’s the best way to apply the solution, sponge, roller?

GK CFW is very forgiving, as long as you follow the dilution instructions and saturate the surface you can even apply with a watering can, with a garden pump sprayer, paint brush, sponge, trigger spray or roller whichever suits.

Can this be applied in wet conditions?

Apply the product in dry conditions.

Can this be used on KREND?

Yes. Because it only attacks living bacteria it has no impact on the substrate material to which it’s being applied.

Can I use this on pebble dash?

Yes, CFW is safe to use on all substrates, although we do like the surface to be saturated so coverage may not be as great as that of scratch render.
