Weber Has A Good Back Up And A Guarantee, But Over Here In The Uk, It Is Howtex Adhesive With A Weber Sticker. I Find It Hard To Use And Not Easy To Spread. The Floor Adhesive Is Like Spreading Chewingum. I Have Worked Over In France For Two Years Using Weber Adhesive, It Is Totally Different And Easier To Apply. In The Uk I Would Recommend Bal Adhesives, Much Easier To Use.
