5 Simple Ways to Prevent Ridging

ridgingRidging is a term used to describe an increase in coating thickness that appears as lines or marks in the finish that usually travel with the grain of the wood or can become a problem when applying finish across the grain. This type of surface effect is caused by a thicker line of finish being applied along the edges of the applicator such as a T-bar, roller or paint pad not leveling or flowing out upon drying. This surface defect is made worse by fast setting environmental conditions during coating, i.e. high temperatures and/or low humidity. If it dries too fast, the normal ability of the finish to flow out is impaired. Other possibilities for ridging can be caused from an improperly mixed matte finish leaving gloss differences (streaks) that may look like ridges, applying a finish on a hot floor or an improper sanding sequence.

If you are experiencing ridging or streaks on your floor, you have come to the right place. Here are five simple prevention techniques that can save you from a streaky floor.

1) Make sure all applicator pads are clean and soft all over. Even a couple of hard hairs can leave buy generic cialis usa distinct lines in the finish.

2) When the sun is shining through a window onto the floor, cover the window or coat the floor when the sun is not shining on the floor.

3) When using a T-bar applicator, do not lap over more than 2 inches under fast setting conditions.

4) Close up the job to apply finish and open up the job to dry after the finish has flowed correctly, 30 to 45 minutes after coating is a good rule of thumb.

5) Be careful of your applicator technique. Never leave lines across grain where possible. Apply heavy enough that the finish stays wet long enough to flow out on the floor during hot, dryer conditions.

If you are still experiencing floor ridging after practicing the above prevention techniques, we recommend you contact a Basic Coatings® representative to further assess your needs.
