I luv my DIY but have found that on the whole these pens are not much use. Maybe they have improved since 3 yrs ago since I used them last. It depends on how good a finish u want. Good luck
Really? Damn, I've just ordered some! Got a problem with mould in the shower enclosure despite using all the anti mould sprays ect.. Just re - sealed it all yesterday but the grout in between the tiles is still awful. Thankyou anyway gadget x
Try spraying it with a very strong bleach solution and leave it on for a while - it worked well on a mouldy shower curtain - got rid of all the black mouldiness.
Hi sachs Lakeland have a very good product for getting rid of and preventing mould in the shower. Have a look at their website, thay do mail order.
