"Was concerned before purchase because it was so much cheaper than other similar products, but there was no need to worry as it is a very good product with very good stickability to interior wooden treads and good coarseness to stop slipping, very good product would recommend. Picture shows staircase with tape on tread edges."
"Not being advised regarding outside use, it is normal to presume that it will be ok. I cleaned, dried and sealed 3 separate areas, one of which has had no foot traffic. Absolute and total failure on all 3!
