Construction Adhesive Review
If you’ve recently visited the construction adhesive aisle at a home center, you may have noticed that there are A LOT of different adhesives on the shelves. And with that many choices, choosing the best one for your project can be daunting task.
To help clear up the confusion we decided to find out which of these 10 adhesives were the top performers. In addition to finding out which were the strongest, we also tested which adhesives worked when they were cold and which held the best on wet surfaces.

How Much Weight Can Construction Adhesive Support?
Strength is obviously what most would consider the crucial characteristic of a construction adhesive. For our first test we wanted to push each of these adhesives to their breaking point. For this test we stuck with standard multi-surface adhesives.
The test was fairly simple in design. First, we glued blocks of wood and PVC to a plank of 2×10 used a notched spreader to ensure that each block received the same amount of adhesive. Then, we let them cure for 40 hours.
To test the strength of each adhesive’s bond, we hung a 5-gallon bucket from each block and poured in sand using a 1-gallon pail. In order to remove time as a variable we poured in one gallon of sand every 10 seconds. Some of the adhesives held so much weight that we had to add five and ten pound weights on top of the bucket full of sand. When a block finally gave way, we weighed the bucked and recorded the results.
