Is there an home alternative to K-rend scraper?

[richjwhit]

Hi. I’ve just repairs a crack in our 10 year old k-rend which appeared under the window by our front door. I think the kids slamming it everyday have caused it. I used the k-rend colour fill in ivory and although it was £39 for one small tube it appears to be very similar colour and texture. My question is, what can I use now it’s fully dried to blend it in? I used a sponge as advised by k-rend after each layer to give it some texture but I’d like to give it a final blending. I dont have an k-rend scraper, is there an alternatives home option? Like a scourer on the back of sponge or anything similar.
