Re: How to remove old tile mastic?
A simple scrapre (think of a garden hoe that's straight instead of bent 90 degrees to the handle) with a sharpened edge may do the job.
You don't need to get it all off. If it's pretty close to smooth, the foam underlayment used under laminate will easily mask slight roughness.
The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
